- Screwdriver
Steps for How to Run Underground Wiring to a Garage:
1. Call the local utility company and have them check for buried pipes or wires.
2. Rent a gas-powered trenching machine and dig a trench at least 12 inches deep from the house to the garage.
3. Bore a 1½-inch-diameter hole through the house wall and into the basement with a drill and hole saw. Position the hole directly above the end of the trench.
4. Cut a length of ¾-inch-diameter plastic conduit to extend from the bottom of the trench up to the hole in the house wall.
5. If necessary, use a propane-powered heat gun to bend the conduit to conform to the foundation.
6. Attach a plastic conduit outlet body to the end of the conduit.
7. Push a length of UF (underground feed) electrical cable into the conduit, then feed the end of the cable through the hole in the house wall.
8. From inside the basement, pull the cable all the way to the main electrical panel. Secure the cable to the overhead joists with cable staples.
9. Go outside and lay the cable into the trench, running it all the way to the garage.
10. At the garage, repeat Steps 3 through 7 to install the plastic conduit and cable.
11. After feeding the cable into the garage, screw the conduit outlet body to the exterior wall of the garage. Screw the other conduit body to the house wall.
12. Apply exterior-grade acrylic-latex caulk around the conduit outlet body to seal out water.
13. Cover the cable with about 2 inches of sand, then lay caution tape on top of the sand along the entire trench.
14. Backfill the trench with the excavated soil.
15. Have a licensed electrician make the final wire connections in the garage and at the main electrical panel.

My dad had a trencher. It was me and my three brothers. R.I.P. dad and thanks for the work ethic😀
Haha I have two young boys and that is my gameplan for when they are a bit older.
My dad had the same except it was just me at 6 am with a shovel and wheel barrow... my 2 younger brothers got to sleep in
Good one.
You got that right 🤣🤣🤣
Your Dad was a wise man. May he Rest In Peace!
I hired an electrician to run an outlet 35 feet from outside breaker box to a hottub. Used a GFCI breaker and that PVC wire laid in the trench. Not only did he do a terrible job, (I had to show him how to tin wire to put an outlet together, provided my tools so he could get the job done, and dug 3/4 of the trench because he was going so slow), but 2 months later, I'm ripping the wire back out of the ground because it seems moles have opened that waterproof protective covering. Glad I didn't dump a load of concrete on top of it! Yes, I told him there were moles in the area and he said "They may think the wire is a root". but did nothing about it.
Once again shows me most contractors are worthless since I have to go back and fix what they screw up 99% of the time. I'm always relearning that lesson. Do it myself so it's done right.
Great tip with heating & bending conduit.
Enjoy the show & videos.
It is...until you need to replace it or run another line. Have fun digging again. Conduit people, CONDUIT!
Except now it's harder to dig due to the existing wire down there.
@@Arieeeee ignore it. Replace that wire when you dig the new trench. Wires cheap
That's pretty much the only thing you can do at that point, but it also means you have to spend time on all the connections again too. Digging an extra 6 inches and spending an extra $20 on getting some PVC pipes and glue would be the "right" way to do it while you're spending money on the digging. Even if Scott didn't do it, he could have mentioned it.
JUST DO IT! CONDUIT! 😀
Amen and amen and use a bigger pipe then you think you need
All that work for a single circuit but i'm sure the customer like in most cases wanted to take the cheap way out and do the bare minimum. I always recommend running at least a 30 amp feeder to a garage. People always overload a single circuit in a garage. They start putting extra freezers and fridges in the garage and in the winter run an electric space heater. Then you have all the power tools people use. If you are going to dig up the ground like that might as well spend a little more now then a lot more later. Yeah its' about $150 more for 10-3 vs 12-3 for about $50-$60 for 100 feet but the same labor.
YES! I found that 4/4/4/4 SER wire was around $22 more then 10/3 wire, for the 100ft run to are other building, so 50 amps or 30 amps was a 22$ difference (and a few other small changes for a lager wire and AL wire). I still breaker-ed at 40 Amps but why put the money into something and only pull 20 amps with no way to upgrade!
When I put in a wire to my garage I put in a 3/0. It ran 200 feet away. What a shame all this work and you have limited capacity for future
Plus all that work of digging to not put it in conduit so if it gets messed up have to dig all over again
Just makes me wanna go re-do the job all over again
number 4 individual wire. 100a. And run another conduit for CAT5 , phone line, and RG6 cable tv
This video answered the burning question I had of how to secure LB box to the wall. Thank you for posting this video. Now I can finish installing my floodlights above my garage!
haha, i was looking for a video to explain the same thing and also ended up here. looks simple enough but i've been anxious about cutting a hole through an exterior wall
I miss Scott. He was great
I would've used a heavier wire for drop with a feeder panel in the garage. Then you can add on compressor, and heaters.
12 inches would be too shallow
I would too, But most people just live and pay bills with zero intentions on hobbys
He should have run a 30Amp or higher circuit in conduit to the garage and put in a sub panel. Then put the lights and outlets on separate breakers.
This show is great. Never knew I could form fit conduit pipe!
Code or no code, running wiring under ground should ALWAYS be in conduit.
It's very possible, I'd say highly likely, to keep going past the sand and caution tape without seeing them because they're soft, easily cut with a shovel, and provide zero resistance...... that shovel can still go right through the electrical line with no problems if someone is digging through without looking. Conduit will provide certain, immediate feedback that something is down there even if you don't see it.
yes totally agree , there is no protection for the cable under the ground , so very dangerous installation
It is on an RCBO, We allow in new zealand cables buried direct but fairly deep. 500-700mm i believe. At least sand was used ;}
it's water proof, dude
@@jamedlock83, no one care if it's waterproof or not. He's talking about it being safe in case someone is digging in that area later on.
@@jtltet Nothing would happen other than the breaker tripping, whoever's on the other end of the shovel would be fine. They should have run conduit because all underground wiring fails eventually and if you have conduit you have a race to pull new wire through.
This is what I'm doing this weekend!
Looks great, thanks!
Nice and clear explanation
Good job!
The cable you showed at the start of the video looks similar to the cable we use for wiring in the UK - it's called twin and CPC (earth/ground).
This is great!
I have been doing electrical work for 31 years and had my masters ticket for 24 there is no way i would do this to a client. PVC is cheep digging a ditch is not. Use conduit don't re-dig a ditch.
Maybe he should have put in a concrete encased duct bank with two 4-inch PVC conduits with 4-way innerduct? I mean if you want to do it the "right way" let's go all the way.
you mean to use tubing to protect the bare electrical cable in the dirt? I was wondering why there is no protection
He means use conduit so if you ever need to upgrade or replace the wiring, you just slid it thru, if you direct buried the wire it would require a new ditch
maczrule that depends on how much the customer wants to pay. If he's not intending on adding to the garage than the wire is fine. The only thing I would've changed is using emt instead of pvc coming out of the ground.
EMT will rust in the ground. PVC will not.
I would continue to use PVC pipe going out to the garage with the wire threaded into the pipe to protect it even that much more. I've done it before, threaded the wire into the pipe, and ran the wire out to the junction box into the garage, first, then ran the wire into the breaker box and connect up the breaker in the breaker box. I'm also kinda funny about marking my lines with a black magic marker so they are marked from beginning to end so you KNOW which line is which, and eliminates confusion as well as marking the breaker inside tag so you KNOW how to kill the power if you need to to do further electrical work inside the garage, or to change things that might needing changed or rearranged for the future.
An electrical conduit would allow for future wire upgrades and such along with protection. CATV, phone and ethernet could be added as needed at a later time. A pull string or cord could be added to assist in adding these cables later.
Its also recommended to install 2 pipes for safety that way the power and the data are separated to make sure interference is kept to a minimum.
I do agree that a conduit in the trench would be a better solution, but you wouldn't want to run twisted pair copper(ethernet) in a conduit that has electricity as the AC will create a lot of interference. A power line network or a wireless solution would be simpler for something like this.
CAT7 copper has aluminum shielding around each twisted pair in addition to shielding around the entire cable, not sure if it's enough for 10G running in the same conduit as electrical wiring but I bet it'd do 1G just fine
Glenn Watkins bv
Not code compliant to run CATV, ethernet, phone in the same conduit with 120V AC.
My brother and I ran wire to a pump house and we didn't take shortcuts or spare expenses! We ran it into conduit pipe! Sand doesn't mean anything to me when I am digging! Plus it saves time having to replace the wire when you cut through it with a shovel or ditch digger!
What is sand going to do if you are digging conduit is more safe and it will protect it more. In the UK we have to use armoured cable when we are going underground
Lol! Vin Diesel takes up installing a cable)
Shouldve done XXX part 2 instead of the pacifier lol
When I built my house I rand conduits everywhere I might decide to take electric in and outside. Smartest thing I ever did.
If that's the smartest thing you ever did, I'm afraid to know how the rest of your life is going.
@@Pyth110 Smartest thing while building the house, Nimrod. It's saved me tens of thousands.
If you’re going thru all the work of trenching, put the whole run in conduit. Direct burial wire is a bad idea. And your garage door on a GFCI breaker will have nuisance trips.
Its fine, I’ve done this 20 years ago and no problems.
@@Bamazrollin ok thanks, I’m glad you cleared this up for me.
Always better to run conduit… even if it’s PVC. It allows you to add extra circuits later if you need them. And because a garage can double as workspaces or living spaces… You will surely need extra circuits.
Actually the proper way would be to add a sub panel if you plan on adding circuits.
I was wondering about this. Ok so I'll run PVC, but what size?
@@nofurtherwest3474 it all depends on your situation. It depends how many circuits you need, which will depend on what the purpose of your garage is. A good option for most, which has been suggested here, is to install a subpanel in your garage. A 60 amp sub panel would require #6 copper wires and is enough to satisfy most garage. In today’s world, you need to consider potential larger electrical, demands such as car, charging. Yes, direct burial cable is always an option but conduit has a greater degree of protection for the conductors, and if you oversize the PVC, there will be no need to dig up the ground again just to add more wire.
Whether you were running wires for branch circuits, or wires for a sub panel, Its always good to slightly oversize the conduit. The bigger the conduit, the easier it is to pull the wires through, and to add future circuits if necessary. And no matter how few circuits you would be running, even if it’s just one circuit, I would install nothing less than 1 inch PVC. I would consult with a local electrician for advice when you make your decision.
@@KevinsHeaven ok thanks! Should I try this myself or hire an electrician to do it? you said consult with electrician, do you mean hire them? I already know there's no other utilities using the run from house to garage, so I can dig.
@@nofurtherwest3474 I wouldn’t necessarily fire them unless you had the funds. But if you know someone who’s in electrician, you could ask some basic questions that might pertain to your specific area. You may want to ask them how deep your trench should be for your conduit. Don’t hold me to this, but I think it’s 12 inch minimum depth… Deeper if under a driveway. Anyway, it’s a good way to save money if you dig the trench yourself. Cutting and gluing PVC is very easy. I suggest specifically searching TH-cam with using PVC and trenches keywords and you should get lots of helpful tips. If you are just running one or more individual circuits, it’s definitely doable for you if you have basic mechanical skills. The videos will show you best methods for getting out of your home with the circuits and into the garage structure, from the outside in good luck! Sounds like a nice adventure awaits you.
when I ran electric wire and a water line 200 ft to my garage/workshop it was buried 30" deep. I used 2 0 wire so I could have a 100 amp breaker in the garage and the wire was run in conduit big enough for future wiring if needed, also ran a small rope in the conduit to pull future wires if needed. ran the water piping in conduit due to the rocky soil. it was a beast of a job.
Can you tell me more about your installation? What type or rating of 2 0 and how many conductors did you use? what wire did you use to make the run from the panel in the house to the outside wall? Did you drive a ground rod? If you did drive a ground, what did you do with your 2 0 ground from your homes main panel? How did you find a breaker on your main panel which could fit the 2 0 in it's lugs? Thanks. Working on a similar 4 AWG (50 amp/ 120 ft run) installation.
2 0 wire from the 200 amp breaker in the main breaker panel in the house all the way to the 100 amp main breaker panel in the garage 200 ft away. wires buried in pvc conduit 30" deep outside the house. ground wire from main panel in house connected to delta grounding set up outside. delta is 3 copper rods in a triangle each rod is 6' apart with copper wire wound around each rod and back to the main panel ground, it is extra protection from power surges. also grounded panel in garage with one ground rod. my electrician friend connected the wires in the main panel so I am not sure what he did. we also came into the crawl space foundation wall using a l b and supported the crawl space wiring on the floor joists. it was a expensive beast of a job. wrestling that 2 0 wire into the conduit was like trying to stuff a elephant into a refridgerator
The power to my workshop outbuilding is run using this. I thought someone had just done a hack job and I was sure there was supposed to be conduit. It seems this isn't ideal, but at least I know I don't have to dig it up and replace anytime soon.
So easy.👍
I’m just here for the comments
I ran electricity to a stable for our mini horse in this way, but 30” deep, except one area that was not possible, then 18” and in conduit. 1 circuit for lights and a water de-icer. Fed it with a ground fault/arc fault protected circuit. Easy peasy.
I want to run wire in sch40 from my outdoor breaker panel to an ac disconnect. Do i have to use uf cable in the outdoor conduit?
How do you run the wire into home/through the foundation, assuming it's not in a jacket?
Alright! Very Nice! Cool! ... that guys got some acting chops!
if using gfci will it trip if you used the welding machine in case of overload?
2017 code says you can't do this no more, for all the homeowners that want to do this now. Garage outlets have to be dedicated 20a gfci. And plus in this installation you need a disconnecting means at the first point of entry.
Craig the real MVP
No ducting...good one! Cowboys :D
like this vídeo ...very good
Question: Why only 12 inches and not 18 inches? Does being direct burial have something to do with it?
What's the amp load on this set up? Doesn't seem enough to run all the stuff that's usually in a garage.
What gauge wire was used? Can I use 14/2 for one outdoor outlet?
how far down do you put the red caution tape
Nice 10 amp service there
Im having a similar situation right now. I lost power to the garage and it looks like I need to re-wire it underground. I want to know much digging i need to do to pull out the old wire. I have no idea what they used to wire the cable when the house was built. The house is a 1968.
Why wasn't there more information on the overhead wire from the house? Was that part of the job? Or was it already there? If I want to run power from my house to a garage with no power, do I need that wire too?
Can I use wire that can be buried. Do I still use conduit?
I agree with all the folks about the conduit. Also, I'm wondering how you would get 240 to the garage?
instead of two wires ( black + white ) run a three wire (black red + white) the black and red will each carry 120v giving you 240v the white will be the nuetral for each 120v high leg. The amperage you require will determine the size wire you will need to install. You will also need to install a double pole circuit breaker in your main panel to feed the newly installed three wire
what about critters chewing up the wire in the ground? could happen
Who is addicted to these videos and dont even have a house of yourself
Nothing is more expressive than doing a job twice
lol so cool to see other youtubers on totally different channels than their own haha hope you are doing well!
You would think they would clarify for those who will do this themselves. No conduit required if buried 24 inches or greater.
Cowboy Boots wrong
If it’s GFCI protected than 12 inches of cover is allowed
@@leonardholt5311 code in VA but obviously you know everything everywhere.
Hi there. Such different wiring in USA!
I generally run a 6mm minimum cable to a garage (depending on distance). All that work, you might as well allow for things like garage conversions to a flat etc.
Great trenching. Thats good. We in (australasia) mostly use a conduit for protection in the trench.
Good you use an RCB at the switchboard. Quite interesting to watch the fact you use bare earth cables. We stopped that in late 1960!
Please note that a test of installation should be required (loop impedence, insulation, earthing etc) perhaps your rules are different?? Perhaps DIY jobs dont need these tests in the US?
Great video, i love watching this channel.
I think it varies based on the city.
Did you get it inspected?
Great video very thorough. Truth is if rats get in and eat the wire or something of that sort it's much easier to shop vac fish a new wire then to re do the digging. Conduits cheap on the contractor side. I would run pvc or conduit.
Great Point, this helps with my project , Will get some schedule 40 PVC unless Schedule 80 is needed.
I always install pvc conduit.
I done the same way,good job
I liked the guitar playing.
hystat Agreed. Some tasty, bluesy licks.
I thought the NEC (300.5), required direct bury cable to be 24" underground or 18' if under 2" concrete slab. Are you sure about the 12".
What if I can't go that deep? My brother in law already run water lines and electricity to my garage where my parents live. The problem is that when my mom turns on microwave and minisplit ac it trips the breaker and also a combination of other appliences.
The garage has a lot of outlets and I think they are on a 20amp breaker with a 14 gauge romex cable and brother in law also got electricity from the exiating 220 0r 240 outlet in garage to add more stuff. When breaker trips the whole power goes out in garage and also in kitchen of the main house. I think circuit is overloading.I was thinking of adding a 60amp circuit to main box and running a new line to garage and in garage add one of this boxes Eaton Corporation Br816L125Fdp 6 Circuit Main Lug Load Center, 125-Amp???
Also will I need to cancell all existing outlets and start from zero or is there a way to just add the new line to existing outlets in garage??? Thank u
I need to do run a underground water pipe to get water from my house to the garage. Any suggestions? I don't see a video for that. It is similar situation but it is water. Thank you
Like electrical work, you would need to shut off the water supply, you would first plan your route from the pipes you want to cut into and have a Y in the pipe soldered. One line of course for the current water passage, the other for what your wanting to put in and run out to it's destination. When you trench, has to be below freezing line into the ground. I've never heard of using pvc pipe to protect copper pipes from freezing, however it's not a bad idea to have them incasing the copper pipes going to it's destination. Plumbing issues have changed over the years, use to be all copper pipes, flux and soldering after you've shined up the copper pipe and put flux on the copper fittings and using a damp rag along with a propane heating torch to melt the solder into the pipe that is drawn in by the flux, and once the fittings are securely soldered, you use your damp rag to go around the pipe for a much more smoother, neater job in soldering. They also have crimp rings used when making connections to copper pipes, the more you tighten the connector, the more the crimp ring forms a more secure hold onto the pipe with no water leaks, thus bypassing soldering. PVC pipe and glue is the more modern way of plumbing in newer homes these days, channeling water to it's various destinations throughout the house. After all plumbing connection are made, then you turn your water back on, checking for leaks before backfilling or checking the Y pipe you've just cut in and soldered to divert water to an additional location that you want.
Love the electrical tape over the main breaker to not let people know that they are working on the breaker box with the main breaker still on (like I'm sure lots of people do to avoid having to reset the clock on the microwave).
What if I need to split it halfway to two different locations and I want it in conduit? Can you bury a junction box?
Kevin and Darina S the purpose of a junction box is to have access to the connectors. Cannot bury one to my knowledge. Run a second cable to the other location.
If spending the money on a machine trencher, might as well run a conduit or two, to run a feeder circuit for a subpanel, and a spare for telecomm wiring
Telecom wiring, why?
@@Bremend in case you want internet, speakers, irrigation control, cable, alarm, intercomm, or other low volt systems that require low volt wire. You cannot run low volt wires through the same conduit as 120v power wires.
If they say it's legit to run it this way then I'm sure it is, however I would definitely spring for the extra $30 bucks for some PVC conduit. Seems a bit sketchy to me. Low voltage wiring is one thing, but this isn't low voltage.
according to the electrical code, this actually is considered "low voltage"
"high voltage" is transmission and distribution lines
you're thinking about "extra low voltage", i.e. 24V and lower
I thought it was against code to run UF wire inside a structure? Please comment. Thanks
Craig's best comment- "Cool."
Very interesting to watch this for learning purpose!
It's me,
Sule Shangodoyin.
lol
Keep the videos coming! Always love seeing the perspective of other entrepreneurs 🚀
What torch was he using?
I never do direct burial wire. Always wire in pvc conduit
Question.... If I'm running coax cable AND electric, do i have to separate them in anyway? I hear there may be interference with the coax if they lay together.
Yes they should be in separate conduits.........
million!
Since you had the trencher. Why bury it at 12 inches. Why didn't you put it 2 to 3 foot down. And yes def use conduit. Any nick in the wire. Once it heats up and the moisture. That wire will burn and short out the breaker.
Made the big ass trench... Might as well throw conduit in to it. Why does This Old House hate Conduit? It is easy to work with and easy to bend the pipes with a cheap pipe bender.
All that work you might as well have piped the entire thing and provided future access if you need to pull something or replace it
Because the wire is buried only 12" deep you should pour concrete over it. Cover it with sand first, then the concrete. See 340.12
Interesting, codes do vary. Here unprotected wire is buried 12'', but in the video entitled '' NEC Code on underground wiring #3 Z 120 '' the wire is nestled inside a schedule 80 PVC pipe, the TOP of which is 18'' below grade ?.......Personally, I would feel much better about putting the wire in PVC and checking with the local code for their required depth.
All the money spent on a trencher and sand to backfill, you could have spent another $25 for conduit all the way. Then, you could have used THHN wire and saved more money. Whoever planned this job didn't do well.
Most THHN wire nowadays is rated THWN as well.
How can I figure out what size breaker i need to in my main panel to feed my sub panel that I'm installing in my shed..... i want to put two 220v , eight 110 plugs and 2 overhead lights? also what size wire would I need to go from the main panel to the sub-panel 150 ft away.
Depends what kind of 240V appliances you need to run out there, and how much power they use. We need to start from there. The lights use negligible power, since they are all LED. Then two 20A circuits for the 120V outlets (4 on each).
table saw at 220, miter saw, 110 drill press 110, dust collector 220, Router table 110.
I would run three #2 THHN/THWN copper conductors, along with a #6 green grounding conductor, all in 1-1/4" PVC conduit, and a 100A subfeed and breaker in the main panel. In the shed, use the Square-D Homeline panel rated at 125 amps, with 12 spaces/24 circuits max, from Home Depot. The trench needs to be at least 18" deep. Be sure to pull a permit and get an inspection. And the inspector needs to see the open trench before you backfill it.
With that trench I would have run a higher ampacity circuit and put a subpanel in the garage. Conduit at least 24” also. Maybe the main panel was at it’s limit?
I'm curious, is this 10/2 wire he is using? I want to make a man cave out of my shed. would this wire be heavy enough to power outlets plus an AC window unit, a fridge and stovetop?
no, you need a sub panel for that much. all three of those you listed should be on their own circuit.
individual number 4 wire. 3 lengths.. 220 and one neutral. Put in gray pcv pipe. Used a 220 60amp breaker in the house, and 12 space breaker box in garage with 100a main. Run another pipe to run cable tv, cat5
No frost sleeve?
Had a contractor install regular solid conductors in EMT with screw fittings about 12” deep. He said it’s fine and will last 75 years before the galvanized coating Corrodes. Is he right or cutting corners ?
It can be buried directly in the soil but has to be protected by corrosion protection which galvanized is not. Emt , unlike Ridgid or imc,is not galvanized. It's a zinc coating. The conduit must be wrapped with an approved PVC corrosion proof tape. If you put in pvc pipe but converted to factory galvanized 90° elbows coming out of the ground, you still have to wrap the elbows with the tape. The tape is PVC and it's about 2" wide.
Does this type of electrical cable comes in 220V?
🤣
Just curious Mark what kind of wire was that? I need to run some 110 to my garage and one line of 240. I know codes vary, but generally speaking what would you recommend? I want to do it budget minded, but correct. Thanks in advance for your advice. God bless.
Jason Gongwer that was 14-2 UF (Underground Feeder)
I would run a 100 amp sub panel with 2 inch pvc. I think that is 1 gauge copper.
That's exactly what I did to my one car garage. I have a 100 amp in my house and then I ran that wire to my garage underground. 18"deep..NOT 12" deep.
The question I have is could have I use 10/3 wire under ground to home to garage And also about that white wire, GCI breaker coming from the main panel.(HOMELINE) Do I need to get that one?? I think he used a 30 amp breaker. Is that OKAY 👍 👌???
awesome ^_^
It didn’t look like you glued the conduit to the LBs. also, it looked like you might have bent the wire pretty sharply as it entered the conduit at the garage. The conduit doesn’t need to go to the bottom of the trench.
You mentioned burying 12 inches deep. Be sure to check code and local requirements. Some require 18 inches unless in conduit.
If I was the owner, I would like to put a conduit pipe in for future use
Candu it is not recommended for that type of wire by laying it in the ground a keeps it cool
the covering provides the waterproofing
Trench in New Zealand needs to be 2 ft deep
I hear a lot of people talking so badly about how TOH does a job but if anyone of the tlTOH contractors came to help me I'm sure the job would have been done right and would work out even better than anything I would have done alone.
A few discrepancies: not sure about NEC but the CEC requires direct burial cable depth to be 1.5ft deep and a GFCI is not required. GFCI's are governed by other code rules for outdoor receptacles, etc. Also the sand doesn't serve as a warning when digging it's purpose is to ensure the wire is not damaged by any rocks when backfilling.
"1.5ft" if you're going to use Imperial, at least do it properly... 18"!!!
@@walterbrunswick from a guy who talks to squirrels. "ft" is the standard notation whereas the prime ' (for foot) and double prime " (for inches) are shorthand alternatives not normally used in engineering since it is easily misprinted (i.e ink issues). Reference ANSI "American National Standard Institute" OR for the layman Wikipedia: en.wikipedia.org/wiki/Foot_(unit) OR USA Gov: www.fdot.gov/docs/default-source/roadway/ds/15/ser/AbbreviationsAndSymbols.pdf
@@pierredoucet4556 I'm talking about using decimal notation with Imperial measurements!
What is 2.7ft?? wtf talks like that when talking Imperial!? we would say, 2' 11/16"!!
@@pierredoucet4556 and leave my squirrels alone🤣🤣🐿️
Edit: that was 9 years ago, poor guys are already dead😢
@@walterbrunswick (we get the smaller swiss squirrels down here; In Ontario they are really big!!)... By "we" I assume you mean construction trade because "we" in Canada use both imperial and metric. It depends on the application; for gas its practical to use BTUs but for electricity its much better to use kWh (or Joules). In any case, fractional inches are common in construction and trades but surveying and engineers use decimals for feet because it simplifies the math (eg. triangulation; a^2 + b^2 = c^2); in fact even in the USA open reel surveying tapes are often graduated in fractional inch AND decimal foot - Note: the french word for "inch" also means "thumb"... so correction above: 18 thumbs. lol
Do I need to worry about planting trees near the wire?
I would describe that as a bodge up job...
I know a guy who used coaxial cable (yes, cable tv wire) to run power to his garage for a single light bulb . years later we still give him grief for that!
I'm confused. If power already existed to the garage through overhead wiring, why was it replaced with underground wiring?
Those saying you would run extra wires to a detached building. You can only run one feeder/circuit to a detached garage as per NEC. Also, although conduit would protect wire from anyone digging and accidental contact underground contact often ends up with water in it over the years from gaskets and seals not being 100% effective. So you end up with wires sitting in water. Also any electrician worth his weight in wire knows pulling through PVC at great lengths offers a lot of friction. In my opinion when done right UF is just fine and save a ton of $ in pvc and labor.
Lastly detached building need a disconnect at the building and a ground rod as per NEC which is not shown in this video.
the song while he was digging the trench sounds a little like astronomy by the amazing blue oyster cult
Not boc.here.but I love Astronomy song
Why didn't they add a sub panel. Ground fault has to run back to the main gfci breaker in the house. All that work for a few outlets.
Look at all the master electricians in the comments. 🤗
I love reading the comments of these How to diy projects and seeing all the "experts" saying it is wrong. There are a lot of different opinions in most so who really knows what they are talking about?
