Been watching your channel for a few weeks now. Your delivery is to the point and understandable. I'm a DIY'er and appreciate someone who "unmuddies the NEC waters" a bit. Thanks!
Missed an opportunity to strongly encourage customers to future proof and get the 50+ amp sub-panel with electric vehicle outlets. I'm looking to get this added to my sub-panel in the near future.
Hey Joel, I have some thoughts. Im a journeyman electrician that studies code pretty extensively. On your video you said that the minimum code required for garages in relation to receptacles is 1- 120 volt, 20 amp GFCI. Im assuming this code minimum is for a one car garage with a garage door that's not powered by an garage door opener. 210.52(G)(1) states that at least one receptacle shall be installed at each vehicle bay. So if we have a 2 car garage then you would need at least 2 receptacles. But these receptacles are permitted to be on the same branch circuit. The tricky part comes in with the wording in the 2020 NEC code. Based on 210.11(C)(4), the branch circuit supplying the receptacle(s) outlets required by 210.52(G)(1), "shall have no other outlets" tied to these receptacles. So essentially, because the vehicle bay receptacle(s) cannot be tied to other outlets and the vehicle bay receptacle(s) have to be installed below 5.5 feet, if you were to install a receptacle in the ceiling for the garage door opener this receptacle would have to be on a separate branch circuit than the receptacle(s) required by 210.52(G)(1). In addition you would also have to figure out how to GFCI protect the receptacle in the ceiling while making GFCI readily accessible based on 210.8.
I believe this is what makes the code complex because the wording sometimes can be tricky.
But I understand for you Joel youre probably not trying to get too much into the nuances of the code. Thanks for covering this topic
you are correct one receptacle per garage door/ this guy thinks he knows all. a master electrician means you can pull permits, not that you are a master. plus this guy is a total hack and does shit work.
2:36 Hey I learned how to measure Garage door outlet placement location! Height of door, plus 3 feet, back in ceiling! Thanks
We need an updated version of this taking into consideration EVs :)
"Code minimum" was our target in this video, but maybe we'll follow-up with some "Best Practice" videos. Thanks for the idea, @the7vin19
@@ElectricProAcademy I know. Great video! Awesome work man. I bet code will change in the coming years for garage minimum requirements. I bet 50A may eventually become a requirement
Something I noticed in my area and it's not directly addressed in the code is garage lighting placement. When we have snow in the forecast people tend to back into the garage for an easier departure. The problem is people can't back up straight in the dark when it's bright outside (too much contrast) so they are prone to hitting bikes and lawn equipment along the sides. Inside lighting placement wider than the vehicle solves this issue. It also makes it easier to walk along the side of the car without shadows, especially for older people. If the auto garage opener has the option you can hook up extra lighting on it's 3 minute timer.
Just a supportive comment. You are referencing a single phase system. For a 240 volt residential input, the reference is Line 1,Line2 and Neutral/GND. Not phase a or b. A residential system is provided by a single phase.
Another great explanation of code. My 40+ year old attached garage is sorely lacking... only 2 receptacle locations and a single light receptacle in the ceiling for the light and opener. This circuit is shared with my basement circuit and is not GFCI protected. My plan is to only have the ceiling receptacle remain on the old circuit, adding two new ones off it (4x 4 foot LED lights and the opener) and put in a new 20A GFCI just for the lower receptacles... a quad box or two on each wall.
I think all the receptacles in the garage, including that ceiling one, should be GF protected.
@@aurvaroy6670 Current code, yes. Mine was installed mid-70s. I'm not touching the lights (except adding one more outlet in the ceiling), which remain on the old circuit. Only the new circuit requires GFCI.
I highly appreciate your help with this videos, and also the variety of content that you cover. I suggestion though, since you cited the NEC code, could you include the section of the code when you conclude the videos?
Good thought, we do try to include it in the description of every video, but maybe a summary at the end would be helpful!
What about the requirement for a disconnect on a detached building?
It’s basically it’s own service.
I feel where the code is leaning would discourage traditional 3 ways from the house to the garage.
We typically use a Lutron pico in the house to control the garage switch.
This would allow ether conductors from the house or garage to be live while the other service disconnect is off.
Depending how the service to house and garage is built of course.
Joel,
Great job here. For the DIY this is indispensable code compliance guidance. Thank you.
I recently watched an episode where you were straightening out a rats nest/immanent fire hazard in an old house you grew up in. Couldn't believe the condition in the basement/panel.
Just a suggestion, I know you do this for a living and are experienced working "live" but I would never trust all the safety gear you are wearing (gloves,boots,safety glasses etc) . Gloves could have pinholes/cuts...etc. With you and family in mind, at a minimum when torquing mains in the panel, pull the meter....it ain't worth it! Otherwise if torquing mains live, guarantee checked safety boots, checked safe gloves and a rubber mat around the left and right vertical edges of the open panel edges so your torque wrench does not inadvertently contact panel. An "arc flash" in your face without a face shield......think about family.
You've got a great site here.........amplify more on safety. I know time is money........but family(and you) first! (meant that as a friendly comment)
Sorry .....And not solely for the DIY.......but for all Electricians out there........especially future tradesman......I know Joel is on the right track here. Ethics.....quality......pride in your work!
I'd like to get to a point where every room has its own sub panel right there, in the room that said panel is for. And each individual light socket, wall socket, etc is on it's own breaker. This way no one is in the dark and needing to run extension cords all over their house should something go wrong with ONE thing, taking out the entire bedchamber or two. Like in this hell hole. The GFCI in the lavatory trips, and the lavatory is out and 3 bedchambers. And the thing went bad too, so all it did is making a buzzing sound. The power never did stop flowing to it, but stopped flowing to everything else.
Quick question does everybody do their switches 44 to the bottom of the box and outlet Hammer height ?
#8 AWG conductor on a 50A circuit seems light. I would most likely run #6. I love your videos -always look forward to new ones. I would like to know why you downsize your conductor?
Based upon table 310.16 #8 copper wire at 75 degree C is rated to 50A. However, #8 romex wire is rated 60 degree C so therefore only 40A rated. Sizing wire is possibly the most confusing thing in the whole code.
5:27 225 Outside Branch Circuits. NEC 225.39 specifies the ratings of disconnects. 225.39(D) indicates the minimum size for installations with more than two branch circuits. 60 amps.
225.39 Rating of Disconnect.
225.39(D) All Others
For all other installations, the feeder or branch-circuit disconnecting means shall have a rating of not less than 60 amperes.
@@ElectricProAcademy Thanks
I was hoping to hear about if conduit is required or not. My attached garage (unfinished cinder block walls) has 1 old-school light bulb on a switch. No receptacles, no garage door opener. I would like to have "more" including supporting a mini-split AC/Heater (the mini-split would be installed to cool the inside of the home on the shared wall with the garage with the compressor running outside the garage.
Sounds like we could best service your needs with a video call: electric-pro-academy.square.site/
I would up grade service to 200amp from standard 150 amp For future use if was planning for shop in garage /
Stash ... just remember that a 100 amp panel is 100 amps per leg and a 50 amp welder outlet or car charger will only be used to 40 amps per leg max. That's a fair amount of reserve power on a 100 amp sub panel. If you want to back into the calculation from the stand point of the sub panel being a branch circuit (80% of breaker rating) then figure it as a 125 panel and you still have at least 100 amps available at the garage.
Incandescent lights work at -30f.
Might be late to ask. Can I have 2 LED shop lights on the same circuit as outlets in a garage?. The circuit is GFCI 15 amp w/ 2 outlets and 2 led shop lights on a switch.
@@ElectricProAcademy 2017 Code Language:
210.11(C) Dwelling Units.
210.11(C)(4) Garage Branch Circuits. In addition to the number of branch circuits required by other parts of this section, at least one 120-volt, 20-ampere branch circuit shall be installed to supply receptacle outlets in attached garages and in detached garages with electric power. This circuit shall have no other outlets.
Exception: This circuit shall be permitted to supply readily accessible outdoor receptacle outlets.
I like to install a 60 amp two pole subpanel in detached garages. It will supply most people with the power they need including exterior outlets on the garage.
Need code references when citing the code!
I thought 6 gauge for a 50 amp breaker.
Code says 1 20 amp per car bay
Can you share the reference, @Brandon Harris?

Right on, thank you! We're gonna need to post an update...
Seems like every attached garage I see (which isn't too many) is pathetic in the electrical department. One light, one receptacle on a wall, and one receptacle in the ceiling. Pathetic. Sometimes it's even a 15A circuit. Doubly-pathetic!
I really have an issue with installing led lighting. They DO NOT last very long. I have a large shop with suspended led fixtures that I am replacing as they go out for over 115.00 each. The oldest fixture is 5 years old and I’ve already replaced 8 fixtures. We no longer throw away a bulb, now we replace an entire device. These fixtures are made by a major brand, not Amazon specials. I’m a fan of led replacement bulbs but not fully integrated fixtures.
