thank you. with all the videos telling you different ways to shoot a video for likes never seems to pertain to me. I just need to do what I do I guess. thanks
I've always understood that a microwave only needs its own breaker when it's built-in/hardwired. If you're just plugging it into an outlet, it doesn't need its own breaker for just that one outlet. Is that wrong?
@@markroberts8975does it “need its own breaker” no, but it’s always best practice if your panel, and budget allow for it. It’ll stop a lot of nuisance trips
When you say “AC". That stands for air condition unit? It’s just to make sure as I’m soon going to wire our house and we have an AC unit. Glad I found you 👍👍👍
Hey buddy like the video . Iam having a little of a problem with some electric with 2 outlets . 1 my dryer sometimes it turns on but then when I hit start it turns off. 2. My stove when we used it on thanksgiving with all the eyes on and oven as well it turned off . Those are my mine problems. My stove has a 30amp breaker . Do I need to put a higher one for it to work as normal? And if I fix the stove issue would my dryer start to act normal?
Great video! You’re helping me learn what to do. I do have a question about type of wire to use and the breaker size. My goal is to install a garage heater that is 7500 W and 31 A. and it is about 25 feet from the breaker box. My fear is that if I use 10 gauge wire and I run it for a couple hours to warm up the garage that I will either blow the circuit or start a fire. The guy at Home Depot recommended I use 12/2 wire but that seems awful low. So my question is, should I use 10 gauge wire, with a 30 amp breaker, or eight gauge wire with a 40 amp breaker?
Thanks for the info. I have a question on wire size. I’m wiring an outdoor shed that we’re going to be putting a washer and dryer in. Otherwise we’ve got lights and a few plugs in there. The power will be coming form 125 feet away. What size wire do I have to have for that? Thanks much!
It’s TACO time! Thanks for taking time to educate … I’m in a 2014 new build house with gas cooktop. I want to switch to induction cooktop that needs a 40 amp supply. I see there is already some type of electrical box with metal cover under the cooktop cabinet - I wonder if it’s been prewired and what rating it is. I’m asking cos the appliance store is quoting $1000 just for installation alone and I think they’re assuming the house needs retired or something. Any advice u have would be appreciated!
I want to add a 80 amp subpanel for my garage. What size of aluminum wire would I need to run about 30-40 feet to power my subpanel? Thanks in advance for your answer.
I owuld go with #2 because that is good up to 100 amps. its hard to fund multiple sizes of aluminum but #2 is all day long and will fit in a 80 amp breaker.
I’m planing to run electricity from my house to a new metal shed. It’s ~65’. I plan to have a couple lights, fan, 4-5 outlets, garage door opener and a window AC unit. I had planned to run an 8 gauge Cooper wire to a new panel then run a separate 20amp circuit for the wi Dow unit and place the rest on a sweater 15amp breaker.
Please refer to the ac's name plate to verify the units amperage and cct breaker. This will help to make sure the branch cct wire to the ac's receptacle. You may want to increase wire size, next size up if need be, but cct breaker can stay the same.
Layman here. I just got a cnc my router runs at 700 w and my dust collection at 750w this need to be able to be sustainable at sometimes up to 5 hours at a time for 3d carving. I see the garage is wited with white wire. If my amperage of my two devices equal 80% or under the existing breaker rating I should be good? My dust collection that I am getting soon is 5.1 amps at 750w My Router is 6.5 amps at 700 w Currently, I run the Router by it self. Because when I run my large shop vac, the circuit pops after around 20 mins of both devices running the shop vac is like 12.5a. So in short my total load on my 20amp breaker should be 11.6a rather than the 17a I've been attempting.
I am installing a heater in my garage. It was pre-wired by the builder. The "white wire" has 220 written on it and the voltage is confirmed with a volt meter. The panel box has a Sq D 20 amp double pole breaker. Installation seems pretty straightforward, black wire to black wire white wire to the white wire, etc. The installation diagram requires a 30 amp breaker. I updated the breaker. The fan works on the heater BUT the heating element does not kick in. I bought the "Oragne" 10-2 wire but before I tear into the drywall will the 10-2 help the heating element to turn on?
I would like to add a dedicated breaker and outlet for my camper. It says that it takes at least a 30 amp breaker but I would be happier to run a 50 amp set up. It is about 60 ft from where my outside meter box is. Can I add a small box under my meter box with a single 50 amp breaker there and run wire 60 ft to another box on a 4x4 pole with an outdoor outlet for my camper supply? And what size wire would you recommend. Thank you for your time. Donnie
A camper is either 30 amperes at 120 volts or 50 amps at 120/240 volts. If you run a circuit and panel, as Starving suggested, from there you should install a single pole 30 amp breaker with #10 conductors to a TT 30 receptacle. If not, you could use a 30 amp 1 pole breaker, #8 or #6 copper (1) hot, (1) neutral, and (1) ground. Larger wire for voltage drop when you turn on the AC. You should not run a 40,50, or 60 amp breaker. Running higher amp breakers than you should is dangerous, not better. Best wishes, Kevin
Quick question: if I have a 30amp generator, would it make a difference if I run all connections as 50amp? Of course I would get an adapter to hook up the generator. But would it help the generator work more efficiently?
Hey. We have a 40 amp break for the old cooktop. New cooktop requires 50 amp. Can we just change out breaker or have to pull a new cable to support the 50?

Great explanation.. I'm wanting to run (2) 220v plugs into my garage 1 for my plasma cutter and 1 for my 60 gal compressor. Please understand I'm a rookie at this stuff and electricity scares me as I have run many 911 calls on people whom have been zapped. Does this sound correct to you...?...My compressor is calling for a 60 amp breaker so Ill be using a 6g wire run from my panel to the plug where my compressor will live...I already have 220v in my laundry room which is on the opposite side of my garage so I was going to disconnect the dryer plug as I do not need it and use that wire for a plug Ill place on the inside of the garage for my plasma cutter. Does this sound right to you Sir? I gathered this info from your educational video. Just wanted you to know you made this very easy for me to understand. Wish me luck Sir.
I live in a modular home with no space for laundry. However, our landlord allows us to wire up washer dryer hook ups in an external shed. I have ran all the conduit I have the washer completed on 12/2 with a gfci plug inside a weatherproof single gang with a lockable in use cover. For the dryer I am using 10 three on a three prong outlet. It grounds at the panel but not at the outlet. It ran with no issue, but had to disconnect after inspection wiring was Janky initially now it’s in conduit with the same outdoor rated two gang box and in use cover. In other videos, they say to tuck the ground towards the back of the gang box is this safe? Or is just how it works with a three prong? Oh, and all the wiring and conduit is ran into the inside of the shed
Appreciated your very informative and to the point video. My question is, I have an unfinished utility room in my basement that has an unused/unpowered box with a yellow, 12 gauge/3-wire (black, red, white) cable running to it which traces back to my breaker box where the wires are capped and unconnected. It appears to have been left for future use. My question is what type of 20 amp circuit breaker do I need to install as I primarily want to have wall type 3-prong 120v outlets. I would like to potentially have it switched also but mainly want outlets with continuous power. What breaker(s) would be recommended for this wiring project? Thanks!
Can you step down the gauge of wire? The question is if you have a 20 amp breaker and you have multiple outlets on it and you are junction in into a daisy chain of outlets running garage door openers can you use a 14/2 ?
I have a tankless hot water heater that requires (4) double 40A breakers but my main panel is maxed out. Would a 100A sub panel using 3 gauge wire be sufficient?
Now for my question, I have a pole barn on my property that sits roughly 75-100 feet from my outside panel that has the meter. I want to add a breaker to that panel and run wire underground to the pole barn. I need to have atleast three available outlets for LED light fixtures, nothing big just extra outlets for power saws or small air compressor. Do I need to upsize my breaker and wire due to the distance from the panel? How deep do you recommend burying the wire?
I’m trying to run service to a shed I’ve got, I’d like to run 20amp for the woodworking tools I’ve got. My question is I’m going from the pole to the shed. It’s about 60’ from the pole to the shed, should I use 10/2 or 12/2 UF-B?
Hello. I want to run a wire from my main breaker box and make another breaker box for my outdoor patio . I was thinking of using a 10/2 wire, probably 100 feet . I dont know that amp breaker i should use on the main breaker box . I want to light up normal led lights and common electronics. Maybe a window unit for my outdoor bathroom. So what breaker should i start from?
I had a 45.4 amp stovetop installed. The contractor who is not a certified electrician ran a 10/3 to the breaker box. I told him that wouldn’t work. Now we’re arguing about the breaker size. He’s telling me a 40 or 50 amp will work. I said definitely not the 40 and now I’m not sure if the 50 is right either. Any information would be appreciated. Great video though! Thanks in advance!
How many amps in circuit do I need to power an electric lawn mower? Currently I have a 15 amp gfi outlet in my garage. Should I bump it up to 20 amp before starting to use my new lawn mower in spring? The reason I ask is because a car detailer came to my house to detail my car and we blew circuit from his compressor type air blower. Thanks much
When wiring a house do I take the length of the runs into consideration? Is voltage drop a factor? And if as long as I stay on code with devices and breakers ratio (ex. 10 outlets to a breaker) ? And thank you for the content 👍🏾👍🏾👍🏾
Quick question, I need to run a line to a dedicated pedestal for an RV pad. The RV requires 30 amp and I would like to add a jacuzzi which has a 110 outlet. what size wire to run ? The run length is 250 ft from the box. thanks so much.
Based on what you said in this video I'm confused. We had electrician out today because we need a new oven. Our was zapped 2 years ago. He said the range and oven are linked together so we would have to replace all of it. The two are on one 50 amp breaker. He said Should be no more than 20 amp. Thoughts?
At what distance are the amp ratings good for.....I'm hooking up single phase 240v 5 hp air compressor approximately 65 feet away from my braker box is #10 ok for that distance?
Hooking up a welder in my shop and the manufacturer’s manual calls for a 50 amp breaker. The total run is 25 feet and I plan to use strained copper wire. What size wire is needed?
very specific question here, is ok to replace a 30 amp 2 pole breaker that currently powers the dryer with a 40 amp 2 pole breaker to add a minisplit on the same 40 amp breaker? the minisplit would be wired using 8/2 cable. it is because there is no more space in the box to add another dedicated circuit for minisplit. 2 different hvac persons have suggested the same option
Great video! But a times a changin again. This is not in the code yet. We got used to white, yellow and orange romex NM-B. Makes things easy. But all these colors only have two conductors and a bare ground. But items like modern stoves and dryers now need a neutral. That is to allow them to run fancy controls off an internal 120 circuit. So new colors just showed up at HD. Purple is 12-3 and PINK of all things is 10-3. I forget the color for 14-3. 😅
What about a 25A breaker? I’m installing a mini split that is 115v 60Hz 1Ph with a max 25A fuse. I’m guessing I need a 10g wire with a 25amp breaker. But does my breaker need to be single or double pole?
So that means that for a mini split with a min of 17 ampacity and 25 max fuse I’m ok with 12/2 wire and 20amp breaker? Please help me? 🙏🙏 Thanks for your help!!
I need to run new wire through a pipe under a driveway between the house and a detached garage. Should I be using 12-gauge instead of 14-gauge given that the wire will be outside and underground or is that not relevant to consider?
So do breaker switches basically act like a step down inverter? like, 600V/100Amps to the Main breaker panel bus bar the breaker is plugged into, > but only 120V/20Amps gets "out" of the breaker line?
I have a 9 kva generator rated 220 volts 30 A circuit/ plug. Can it start and run two hairdryers rated 2000 watts 220 volts each at the same time simultaneously? Another question is, if i Connect the two of them, which mm cable can i use and the socket should be rated how many A. Kindly i need an answer. Thanks.
well do the math. 2000 wats and 120 volts. then times 2 those should be on a 20 amp circuit. This video is to show you how. I want you to learn from it. I wont do the calculations for you. its easy. lol
I had my electrician install an outlet for my welder in my garage and he put in a double pole 50 amp breaker for it. Can I use that same outlet to power my air compressor? New air compressor says it requires a double pole 30 amp breaker.
it will work but not at the same time. also if your air compressor is 30 amps then if there is a fault in the compressor then concieveably the compressor would fry before the breaker trips. its not code but it will work. id just change the breaker if you aren't using the welder.
HELP! I'm replacing an old Federal Pacific 100-amp panel with a 200-amp Square D Hameline panel, so I will need to upgrade the service entrance cable and want to use 2/0 THHN copper. The outdoor meter can/box is mounted low, (30" off the ground at bottom edge of can) outside, so if I use the bottom rear 2-inch knockout of the meter can, it will put the hole through the wall below the bottom edge of the new breaker panel by about 8 inches, so I will have to make a vertical 90 upwards turn from hole in wall to bottom knockout of the new panel. I cannot find a 2" close 90 PVC electrical fitting so I'm guessing they don't make one. My question is: how do I make that vertical 90 turn upwards? It will eventually be covered in drywall. Do I need to have the inside copper leads in conduit at all? If I use switch to 4/0 aluminum, do I need conduit inside the wall cavity? thanks in advance!
I am replacing a conventional water heater with a tankless. After three plumbers and two months I have NO hot water. I have had a dozen conversations with the manufacturer and finally may have hit upon the problem. We've tried to use the existing gauge wires. The new heater requires 60 watts. Although the existing wiring was 240, the wire gauge appears to be to small. I've been shopping for 6/2 wire which is very expensive and somewhat difficult to locate sold by the foot. Also I am told aluminum draws more power than copper. I see conflicting numbers. Some claim 6/2 is good to 55 amps. The manufacturer of the heater claims it requires 60 amps. The current breaker claims 40 amps, which I believe explains why the element never engages. It has taken two months, three (so called) plumbers and about 100 hours of personal research to determine the deficient amperage. The instructions do not mention amps, just watts. The manufacturer did not mention them until today when I pressed for better details of the functioning of the unit. Finally I was told it requires 60 amps. The 20 amp deficiency will require a 60 amp breaker and 6/2 wiring if my investigative abilities are correct. However when I search for 6/2 wire [ I need 10' ] they claim 6/2 only supports 55 amps. Also most scales only reach 6/2 leaving the next size a mystery. I am in Jacksonville, Fl. where good help is extremely hard to find. I am considering taking on this project myself in view of the fact I know of NO reliable and efficient electricians to call upon. I'm old and infirmed but NEED hot water. Any advice or help would be much appreciated~! I can be reached at 904 615 9945 late afternoons EST.
regardless of the wattage you would be better off with a 20 amp circuit. thats required in all kitchens. that will draw 15 amps. you need to be at 80% of your breaker max.
Often wondered why #6 is good for 50-60 amp . Seen some folks say it’s only good for 55 amps others 65 amps. Some folks say a 60 amp sub panel needs #6 others #4 . It’s funny to see these debates over at mike holts forums ….I guess it has to do with 60* vs 75 vs 90* terminations ? If you don’t already have a video on that I would love to see a video on the difference between degree terminations
#6 is good for 50amps when using NM Romex...if you use THHN in conduit, you can get 75 amps, with 90° C terminations...so says NEC 310.16 Copper is copper....wire is all about what material is covering said wire
Question, my electrician hooked up a red wire that reads 800 volts to my garage for my 225 Lincoln arc welder and it was very weak,I opened the breaker panel and the wires were hooked up to 30 amp breakers,can I install 50 amp double breakers to those wires to run my welder?,I'm no electrician lol
Ok I’m installing a wall oven rated at 40amps and need to install 40 amp breaker and wire per instructions it states to use 8 gauge solid however I can’t seem to find 8 gauge solid and appears that it doesn’t exist do I use 8 gauge stranded?
If a until calls for 2 8/2 wires ran on 2 40amp breakers can you use 6/2 wire instead of 8/2 that wouldn't hurt nothing right you just don't wanna go smaller.
nop that would be fine. if you have a corvette but the speed limit is 55 thats ok you got the fast car but you are still limited, just like being limited by the breaker.
First off, my house came with 3 (1) ton units, 2 of which went out so we replaced it with a 3 ton with a splitter. Now we had no issues before until the 3 ton was installed. 30 amp Breaker burnt up going to the 3 ton, had someone replace it last year, a few days ago it burnt up again and it did not trip but unit turned off. We had an electrician come out and he said there is a number 8 wire going to the 30amp and that it needed a 40. Why did the breakers burn up?
Great video and thanks for the info. Quick question.... I'm installing an oven microwave combo that requires 30 amps. There is currently 6-3 wire on a 50 amp breaker. Can I just replace the breaker with a 30 amp? Or am I fine just leaving it with a 50 amp breaker? Thank you!
I have a similar question. Did you figure it out? I have a 50Amp breaker used by a condensor that went bad with a 6 gauge aluminum wire and I was wondering if I can change just the breaker to 35 amp for a MrCool DIY system and keep the 6 gauge going to my disconnect panel.
hey brother,new subscriber here today. just ran a single wired line just for my ac window unit now my question is;for a 8,000 up to12,000 btu whats the wattage + amp for this unit? I used a 15a/14-2 but then it shut my ac breaker off.should I go with 20 or 30?thanks
Read the name plate as he says in the video. The device should give you a rating then size up from there. Always go above the amperage being drawn! Never below it! Each device has it's own ratings. You could just go to 30Amps and #10 wire to play it safe. I'm not sure any window AC's draw more then that but china has made me 2nd guess lots of electronics.
basically most appliances max out a 15 amp circuit. an AC has a continus load so that circuit will get hot and you need a heavier circuit. if its 120v then it should be on a 20 amp circuit. #12 wire. 30 amp could be used but thats mostly for a 220v citcuit. If i had to guess its 20 amp. heres a trick, plug it into a circuit that you know is 20 amp. like the kitchen, if it doesnt trip you know you are good. make sure nothing like the fridge is on that circuit. if it trips a 20 there may be a problem with the unit its self. if you went with a 30 and it didnt trip the cord may catch fire so thats why we run the correct wire and breaker for the amperage. hope this helps!
I'm using 6 gauge copper wire to connect my 50 amp/240 generator to my house. Will having 6 gauge wire draw less amperage than if I were using 8 gauge wire when the A/C starts up?
If I have a double tapped 20 amp breaker that keeps tripping can I switch it to 30 amp without upgrading the gauge of the wiring? It’s currently 12 gauge for both.
Double tapping is bad. Easiest answer is to add another breaker if you have the space, 2nd option is to use a Tandem Circuit Breaker. 3rd option is a subpanel - subpanel seems to be overkill. 4th - add a larger panel
Have a 6.6-7 Kw heater. It says 30 amp, and 8 gauge in the manual. So if it draws 30 amp at 240, (actually 29 amp Amp give or take) at continuous or peak performance why can 30 amp breaker and 10 gauge not suffice. Safety or de rateing factor for heaters? Also aren’t breaker supposed to trip with a safety factor for over amperage.. basically should it match the needs or be sized one larger. As long as the wire matches the breaker what will happen aside from tripping the circuit?
What happens if you draw more amps than breaker? Short circuits can occur when there is an unintended connection between two points in the circuit, which causes an excessive amount of current to flow. Short circuits can cause equipment damage, power outages, and fire hazards. Overloads occur when the current flowing through a circuit exceeds its rated capacity. Does this mean that the wire gauge should rated equal to breaker size?

A camper is either 30 amperes at 120 volts or 50 amps at 120/240 volts. If you run a circuit and panel, as Starving suggested, from there you should install a single pole 30 amp breaker with #10 conductors to a TT 30 receptacle. If not, you could use a 30 amp 1 pole breaker, #8 or #6 copper (1) hot, (1) neutral, and (1) ground. Larger wire for voltage drop when you turn on the AC. You should not run a 40,50, or 60 amp breaker. Running higher amp breakers than you should is dangerous, not better. Best wishes, Kevin
outstanding work sir
Thank for this video! Good clarification.
im glad thanks
Very simple and informative. What size wire do you need to connect the main meter disconnect to a 200 amp sub panel?
What size wire do you use to do baseboard heater and what size breaker?
Quick question: if I have a 30amp generator, would it make a difference if I run all connections as 50amp? Of course I would get an adapter to hook up the generator. But would it help the generator work more efficiently?
Hey.
We have a 40 amp break for the old cooktop. New cooktop requires 50 amp.
Can we just change out breaker or have to pull a new cable to support the 50?
Most likely you have #8 wire coming off that 40 amp breaker. It needs to be #6 for your 50 amp cooktop.
@@Ephesians-ts8zeI'm going all out so I don't have problem ms down the road and get 6/2 125foot for my Hobart ironman 240. it's about a 100foot away give or take.
Great video wish you would have talked about the 60 amp and what size breaker Thanks Very Much
Great explanation.. I'm wanting to run (2) 220v plugs into my garage 1 for my plasma cutter and 1 for my 60 gal compressor. Please understand I'm a rookie at this stuff and electricity scares me as I have run many 911 calls on people whom have been zapped. Does this sound correct to you...?...My compressor is calling for a 60 amp breaker so Ill be using a 6g wire run from my panel to the plug where my compressor will live...I already have 220v in my laundry room which is on the opposite side of my garage so I was going to disconnect the dryer plug as I do not need it and use that wire for a plug Ill place on the inside of the garage for my plasma cutter. Does this sound right to you Sir? I gathered this info from your educational video. Just wanted you to know you made this very easy for me to understand. Wish me luck Sir.
I live in a modular home with no space for laundry. However, our landlord allows us to wire up washer dryer hook ups in an external shed. I have ran all the conduit I have the washer completed on 12/2 with a gfci plug inside a weatherproof single gang with a lockable in use cover. For the dryer I am using 10 three on a three prong outlet. It grounds at the panel but not at the outlet. It ran with no issue, but had to disconnect after inspection wiring was Janky initially now it’s in conduit with the same outdoor rated two gang box and in use cover. In other videos, they say to tuck the ground towards the back of the gang box is this safe? Or is just how it works with a three prong? Oh, and all the wiring and conduit is ran into the inside of the shed
Thank you, sir!!
thanks
Size cables to amperes. Would that still be the same if either 220v or 115v is running through them? 👍👍
Appreciated your very informative and to the point video. My question is, I have an unfinished utility room in my basement that has an unused/unpowered box with a yellow, 12 gauge/3-wire (black, red, white) cable running to it which traces back to my breaker box where the wires are capped and unconnected. It appears to have been left for future use. My question is what type of 20 amp circuit breaker do I need to install as I primarily want to have wall type 3-prong 120v outlets. I would like to potentially have it switched also but mainly want outlets with continuous power. What breaker(s) would be recommended for this wiring project? Thanks!
Can you step down the gauge of wire?
The question is if you have a 20 amp breaker and you have multiple outlets on it and you are junction in into a daisy chain of outlets running garage door openers can you use a 14/2 ?
no because the lighter gauge wire may give out before the breaker trips. just swap the breaker or get #12 wire,
I have a tankless hot water heater that requires (4) double 40A breakers but my main panel is maxed out. Would a 100A sub panel using 3 gauge wire be sufficient?
@@simpleagain1 hope you have a 400a service or you are going to have problems
Now for my question, I have a pole barn on my property that sits roughly 75-100 feet from my outside panel that has the meter. I want to add a breaker to that panel and run wire underground to the pole barn. I need to have atleast three available outlets for LED light fixtures, nothing big just extra outlets for power saws or small air compressor. Do I need to upsize my breaker and wire due to the distance from the panel? How deep do you recommend burying the wire?
you wont see a voltage drop at that distance im sure you could do a calculation bit its verry little. go 24" in pvc you should be good.
I’m trying to run service to a shed I’ve got, I’d like to run 20amp for the woodworking tools I’ve got. My question is I’m going from the pole to the shed. It’s about 60’ from the pole to the shed, should I use 10/2 or 12/2 UF-B?
Hello. I want to run a wire from my main breaker box and make another breaker box for my outdoor patio . I was thinking of using a 10/2 wire, probably 100 feet . I dont know that amp breaker i should use on the main breaker box . I want to light up normal led lights and common electronics. Maybe a window unit for my outdoor bathroom. So what breaker should i start from?
Thank you brother!
Thank you for watching brother
I had a 45.4 amp stovetop installed. The contractor who is not a certified electrician ran a 10/3 to the breaker box. I told him that wouldn’t work. Now we’re arguing about the breaker size. He’s telling me a 40 or 50 amp will work. I said definitely not the 40 and now I’m not sure if the 50 is right either. Any information would be appreciated. Great video though! Thanks in advance!
Good teaching thanks
How many amps in circuit do I need to power an electric lawn mower? Currently I have a 15 amp gfi outlet in my garage. Should I bump it up to 20 amp before starting to use my new lawn mower in spring? The reason I ask is because a car detailer came to my house to detail my car and we blew circuit from his compressor type air blower. Thanks much
Just what I needed to know. Thanks!
I wanted to add a main breaker to my house. Do you thing 100 amp is good enough?
Excellent video
When wiring a house do I take the length of the runs into consideration? Is voltage drop a factor? And if as long as I stay on code with devices and breakers ratio (ex. 10 outlets to a breaker) ? And thank you for the content 👍🏾👍🏾👍🏾
with respect to length its almost never, you would need a run a couple hundred feet before you even say anything.
Quick question, I need to run a line to a dedicated pedestal for an RV pad. The RV requires 30 amp and I would like to add a jacuzzi which has a 110 outlet. what size wire to run ? The run length is 250 ft from the box. thanks so much.
Based on what you said in this video I'm confused. We had electrician out today because we need a new oven. Our was zapped 2 years ago. He said the range and oven are linked together so we would have to replace all of it. The two are on one 50 amp breaker. He said Should be no more than 20 amp. Thoughts?
If wanting to be on the safe side can I use a 4awg copper wire with 60amp breaker for Tesla wall charger?
yep over sizing the wire never hurts
At what distance are the amp ratings good for.....I'm hooking up single phase 240v 5 hp air compressor approximately 65 feet away from my braker box is #10 ok for that distance?
Hooking up a welder in my shop and the manufacturer’s manual calls for a 50 amp breaker. The total run is 25 feet and I plan to use strained copper wire. What size wire is needed?
Why aren’t breakers used at the end appliance wall receptacles? Seems easier to reset there vs walking out to box.
very specific question here, is ok to replace a 30 amp 2 pole breaker that currently powers the dryer with a 40 amp 2 pole breaker to add a minisplit on the same 40 amp breaker? the minisplit would be wired using 8/2 cable. it is because there is no more space in the box to add another dedicated circuit for minisplit. 2 different hvac persons have suggested the same option
Great video! But a times a changin again. This is not in the code yet.
We got used to white, yellow and orange romex NM-B. Makes things easy.
But all these colors only have two conductors and a bare ground.
But items like modern stoves and dryers now need a neutral. That is to allow them to run fancy controls off an internal 120 circuit.
So new colors just showed up at HD. Purple is 12-3 and PINK of all things is 10-3. I forget the color for 14-3.
😅
What size breaker for 8/3 wire at 250 ft distance? I'm using it for the 240vac well pump.
How about 6/3 wire?
What about a 25A breaker? I’m installing a mini split that is 115v 60Hz 1Ph with a max 25A fuse. I’m guessing I need a 10g wire with a 25amp breaker. But does my breaker need to be single or double pole?
So that means that for a mini split with a min of 17 ampacity and 25 max fuse
I’m ok with 12/2 wire and 20amp breaker?
Please help me? 🙏🙏
Thanks for your help!!
I need to run new wire through a pipe under a driveway between the house and a detached garage. Should I be using 12-gauge instead of 14-gauge given that the wire will be outside and underground or is that not relevant to consider?
So do breaker switches basically act like a step down inverter? like, 600V/100Amps to the Main breaker panel bus bar the breaker is plugged into, > but only 120V/20Amps gets "out" of the breaker line?
Great video very helpful
im glad thanks
this was so helpful!
What size wire is needed for a 40 amp circuit fed by two, twenty amp breakers?
THANK YOU!!!
Thank you, if I have a mix of needs for 15A ava 20A circuits.. Could I just use 12Ga wire for all of them?
What do you do if you need a 30 amp wire 200 feet? I heard that you can only go 50 feet with 30 amp wire (10-3)
I have a 9 kva generator rated 220 volts 30 A circuit/ plug. Can it start and run two hairdryers rated 2000 watts 220 volts each at the same time simultaneously?
Another question is, if i Connect the two of them, which mm cable can i use and the socket should be rated how many A. Kindly i need an answer. Thanks.
well do the math. 2000 wats and 120 volts. then times 2 those should be on a 20 amp circuit. This video is to show you how. I want you to learn from it. I wont do the calculations for you. its easy. lol
What wire do I need for 125 amp single phase panel

I had my electrician install an outlet for my welder in my garage and he put in a double pole 50 amp breaker for it. Can I use that same outlet to power my air compressor? New air compressor says it requires a double pole 30 amp breaker.
it will work but not at the same time. also if your air compressor is 30 amps then if there is a fault in the compressor then concieveably the compressor would fry before the breaker trips. its not code but it will work. id just change the breaker if you aren't using the welder.
Thank you!
HELP! I'm replacing an old Federal Pacific 100-amp panel with a 200-amp Square D Hameline panel, so I will need to upgrade the service entrance cable and want to use 2/0 THHN copper.
The outdoor meter can/box is mounted low, (30" off the ground at bottom edge of can) outside, so if I use the bottom rear 2-inch knockout of the meter can, it will put the hole through the wall below the bottom edge of the new breaker panel by about 8 inches, so I will have to make a vertical 90 upwards turn from hole in wall to bottom knockout of the new panel. I cannot find a 2" close 90 PVC electrical fitting so I'm guessing they don't make one.
My question is: how do I make that vertical 90 turn upwards? It will eventually be covered in drywall. Do I need to have the inside copper leads in conduit at all? If I use switch to 4/0 aluminum, do I need conduit inside the wall cavity? thanks in advance!
Any downside to using bigger than strictly necessary? 12/2 when you only need 14/2, for example. Just because it's available.
I am replacing a conventional water heater with a tankless. After three plumbers and two months I have NO hot water. I have had a dozen conversations with the manufacturer and finally may have hit upon the problem. We've tried to use the existing gauge wires. The new heater requires 60 watts. Although the existing wiring was 240, the wire gauge appears to be to small. I've been shopping for 6/2 wire which is very expensive and somewhat difficult to locate sold by the foot. Also I am told aluminum draws more power than copper. I see conflicting numbers. Some claim 6/2 is good to 55 amps. The manufacturer of the heater claims it requires 60 amps. The current breaker claims 40 amps, which I believe explains why the element never engages. It has taken two months, three (so called) plumbers and about 100 hours of personal research to determine the deficient amperage. The instructions do not mention amps, just watts. The manufacturer did not mention them until today when I pressed for better details of the functioning of the unit. Finally I was told it requires 60 amps. The 20 amp deficiency will require a 60 amp breaker and 6/2 wiring if my investigative abilities are correct. However when I search for 6/2 wire [ I need 10' ] they claim 6/2 only supports 55 amps. Also most scales only reach 6/2 leaving the next size a mystery. I am in Jacksonville, Fl. where good help is extremely hard to find. I am considering taking on this project myself in view of the fact I know of NO reliable and efficient electricians to call upon. I'm old and infirmed but NEED hot water. Any advice or help would be much appreciated~! I can be reached at 904 615 9945 late afternoons EST.
Awesome video
Just bought a double oven that sit on the counter. its1800w, will it be okay on a 15amp outlet? Thanks
regardless of the wattage you would be better off with a 20 amp circuit. thats required in all kitchens. that will draw 15 amps. you need to be at 80% of your breaker max.
@@StarvingElectrician thank you!
Often wondered why #6 is good for 50-60 amp . Seen some folks say it’s only good for 55 amps others 65 amps. Some folks say a 60 amp sub panel needs #6 others #4 . It’s funny to see these debates over at mike holts forums ….I guess it has to do with 60* vs 75 vs 90* terminations ? If you don’t already have a video on that I would love to see a video on the difference between degree terminations
thats advanced but I should try it.
#6 is good for 50amps when using NM Romex...if you use THHN in conduit, you can get 75 amps, with 90° C terminations...so says NEC 310.16
Copper is copper....wire is all about what material is covering said wire
@@BlackVibeBallsack thanks!
Question, my electrician hooked up a red wire that reads 800 volts to my garage for my 225 Lincoln arc welder and it was very weak,I opened the breaker panel and the wires were hooked up to 30 amp breakers,can I install 50 amp double breakers to those wires to run my welder?,I'm no electrician lol
For the fridge how many amps circle breaker I have to use
What size of a triple pole amp can I use on a 3 phase instrial oven?
Ok I’m installing a wall oven rated at 40amps and need to install 40 amp breaker and wire per instructions it states to use 8 gauge solid however I can’t seem to find 8 gauge solid and appears that it doesn’t exist do I use 8 gauge stranded?
I have some on the truck now. its very common. it doesnt have to be solid. it can be stranded too
If a until calls for 2 8/2 wires ran on 2 40amp breakers can you use 6/2 wire instead of 8/2 that wouldn't hurt nothing right you just don't wanna go smaller.
nop that would be fine. if you have a corvette but the speed limit is 55 thats ok you got the fast car but you are still limited, just like being limited by the breaker.
First off, my house came with 3 (1) ton units, 2 of which went out so we replaced it with a 3 ton with a splitter. Now we had no issues before until the 3 ton was installed. 30 amp Breaker burnt up going to the 3 ton, had someone replace it last year, a few days ago it burnt up again and it did not trip but unit turned off. We had an electrician come out and he said there is a number 8 wire going to the 30amp and that it needed a 40. Why did the breakers burn up?
Great video and thanks for the info. Quick question.... I'm installing an oven microwave combo that requires 30 amps. There is currently 6-3 wire on a 50 amp breaker. Can I just replace the breaker with a 30 amp? Or am I fine just leaving it with a 50 amp breaker? Thank you!
I have a similar question. Did you figure it out? I have a 50Amp breaker used by a condensor that went bad with a 6 gauge aluminum wire and I was wondering if I can change just the breaker to 35 amp for a MrCool DIY system and keep the 6 gauge going to my disconnect panel.
@@kayrealist9793 Not yet. I'll let ya know when I find out.
I pretty much have same question
hey brother,new subscriber here today. just ran a single wired line just for my ac window unit now my
question is;for a 8,000 up to12,000 btu whats the wattage + amp for this unit?
I used a 15a/14-2 but then it shut my ac breaker off.should I go with 20 or 30?thanks
Read the name plate as he says in the video. The device should give you a rating then size up from there. Always go above the amperage being drawn! Never below it! Each device has it's own ratings. You could just go to 30Amps and #10 wire to play it safe.
I'm not sure any window AC's draw more then that but china has made me 2nd guess lots of electronics.
basically most appliances max out a 15 amp circuit. an AC has a continus load so that circuit will get hot and you need a heavier circuit. if its 120v then it should be on a 20 amp circuit. #12 wire. 30 amp could be used but thats mostly for a 220v citcuit. If i had to guess its 20 amp. heres a trick, plug it into a circuit that you know is 20 amp. like the kitchen, if it doesnt trip you know you are good. make sure nothing like the fridge is on that circuit. if it trips a 20 there may be a problem with the unit its self. if you went with a 30 and it didnt trip the cord may catch fire so thats why we run the correct wire and breaker for the amperage. hope this helps!
@@StarvingElectrician thnk you brother for taking the time and sharing your wisdom.I did installed a 20 Amp and ran it separately and works good.
The guy ran a 14/2 romex...DONT put a 20amp breaker on it...
I'm using 6 gauge copper wire to connect my 50 amp/240 generator to my house. Will having 6 gauge wire draw less amperage than if I were using 8 gauge wire when the A/C starts up?
If I have a double tapped 20 amp breaker that keeps tripping can I switch it to 30 amp without upgrading the gauge of the wiring? It’s currently 12 gauge for both.
no I wouldnt advise that. gonna need bigger wire but sounds like the wiring isnt the peoblem, sound like the equipment.
Double tapping is bad. Easiest answer is to add another breaker if you have the space, 2nd option is to use a Tandem Circuit Breaker. 3rd option is a subpanel - subpanel seems to be overkill. 4th - add a larger panel
Have a 6.6-7 Kw heater. It says 30 amp, and 8 gauge in the manual. So if it draws 30 amp at 240, (actually 29 amp Amp give or take) at continuous or peak performance why can 30 amp breaker and 10 gauge not suffice. Safety or de rateing factor for heaters? Also aren’t breaker supposed to trip with a safety factor for over amperage.. basically should it match the needs or be sized one larger. As long as the wire matches the breaker what will happen aside from tripping the circuit?
Alliminuim? Do I got to retrofit with allumnicon connectors
What happens if you draw more amps than breaker? Short circuits can occur when there is an unintended connection between two points in the circuit, which causes an excessive amount of current to flow. Short circuits can cause equipment damage, power outages, and fire hazards. Overloads occur when the current flowing through a circuit exceeds its rated capacity. Does this mean that the wire gauge should rated equal to breaker size?
Can I replace a 30 Amp with a 20 Amp breaker?. I took out an oven and need to use plug for a microwave
Awesome brother
Thanks for dumbing it down for beginners
What about regular rooms like Bedroom/ living room, etc.
Hi please help. I want a welder in my new garage its a miller 211 what dedicated gauge wire and braker should I use thank you
depends on the amperage first and then you can figure out the wire size
