EMT surface mount outlet plan

[tool_enthusiast]

Missed this earlier......................

My reading of the code is not the same as some people (and I'm not a professional electrician) but many people will tell you that you must have a grounding jumper from the receptacle to the box, even on those metal face plate, 4x4 box setups like GnG used. In most of my installations, I ran the ground wire to the receptacle, and do not have a jumper to the box. the receptacles have a little clip on on one of the mounting screws that is an approved bonding when everything is installed, and I figure the conduit is grounded also.

You can buy packs of the ground jumpers with the U terminal ends crimped on them, and you can always tap extra holes in the box to put ground screws in.

As far at the GFCI, it doesn't use the ground for anything so it will function without a ground at all. Code allows them to be used in two wire systems without a ground and labeled "no ground".

Thanks for responding Charles. I guess the NEC might not be too clear on this? Anyway, I tested my outlets and the ground prong is indeed grounded, so I'm not going to bother with adding jumpers from my receptacles to the box and leave it alone!

It depends on how you started this conduit run. When you added the metal box at the ceiling, did you make a ground connection to the box? If you did, and the conduit run was properly inter-connected with the right fittings, then the entire conduit run should be grounded. Did you test for ground after the install?

Oh yeah. My supply was 12ga three wire Romex. I attached the ground to the box screw then ran it to the GFCI receptacle ground pigtail. Everything with it is tip top and inspector approved.


I asked a question as I got to thinking about the question you posted.

Here's some language I found googling:

Nongrounding-Type Receptacles

406.3(D)(3) Nongrounding-Type Receptacles. Where grounding means does not exist in the receptacle enclosure, the installation shall comply with (a), (b), or (c).

(a)A nongrounding-type receptacle(s) shall be permitted to be replaced with another nongrounding-type receptacle(s).

(b)A nongrounding-type receptacle(s) shall be permitted to be replaced with a ground-fault circuit interrupter-type of receptacle(s). These receptacles shall be marked “No Equipment Ground.” An equipment grounding conductor shall not be connected from the ground-fault circuit-interrupter-type receptacle to any outlet supplied from the ground-fault circuit-interrupter receptacle.

(c)A nongrounding-type receptacle(s) shall be permitted to be replaced with a grounding-type receptacle(s) where supplied through a ground-fault circuit interrupter. Grounding-type receptacles supplied through the ground-fault circuit interrupter shall be marked “GFCI Protected” and “No Equipment Ground.” An equipment grounding conductor shall not be connected between the grounding-type receptacles.

tool_enthusiast - Just remember if you pull that receptacle out hot (which you shouldn't do anyway) it won't be grounded.

GirlnAgarage - That just refers to replacing old receptacles. If there is a 2 prong receptacle and a ground is available in the box, when you go to replace it you need to replace it with a grounded receptacle.

As was pointed out, a 'self-grounding' receptacle has an extra bit of metal attached to one of the mounting ears and the screw in that ear.

Forget those 90 degree corners. Get a tubing bender and go for it. A 90 degree corner is a PIA to pull wire through. If you need to pass an inspection go to Home Depot and get a book called "Simplified Wiring". I wired out restaurant using it and the inspector said he'd never seen a better job by an amateur.

Thanks. You're correct, 90* are a PITA to pull wire through; the 90* bend is easier.

Project is done about a week or two now

I really thought the GJ forum was going to be different that most other mechanical/diy forums, but I see that it is not. ....

This girl started out with her basic plan to add some plugs in her garage safely, and was going to do it to where it was in HER COMFORT ZONE and just needed some basic answers to simple questions, which my first post answered. ...

I could have told her how to wire it to where a nuclear reactor inspector would have been proud. ...

But why ? She is a DIY homeowner, what is the point in all the code quoting and ranting about all of these different wiring methods and getting her all side tracked ??

You guys come along and BLOVIATE and show on line how great of electricians you are, and now look where you have gotten her. She is getting the freaking CITY involved for just adding sone plugs, something she could have done while she read all of these posts, and nobody could have proved who in the hell wired them up later anyway!

Talking about opening a can of freakin worms over just adding some garage plugs !! The city is now involved, does anyone know what the city hoop jumping could end up costing her ?

I see the same thing happening to people everday that come on here and ask how to do the simplest wiring job and lo and behold, the engineers /perfectionist pour out from the walls !

DIY'ers come here to get simple answers for their projects so they can do it safe and cheaper than hiring someone to do it for them. If they have to get bombarded with all the CODES and 100's of wiring ideas, they might as well go take the test and become a electrician.

Plus, Jesus , where are the real men nowadays anyway ???:

If I was single and lived in Texas within a hundred miles of her, I would have already been there and had her garage plugs put in for her for a free dinner. I am outa here, as it is not worth getting my high blood pressure up reading all of this stuff.

Great post. I've been an electrician for a long time an seen stuff that I wouldn't do on the job. Usually the simpler the better. Done stuff for just a beer to help out.

Forget those 90 degree corners. Get a tubing bender and go for it. A 90 degree corner is a PIA to pull wire through.

She wanted to use EMT for its strength, looks, durability, and mostly for ease of cutting and connecting (set screw connectors are so easy). She could have bought pre bent 90's and used two connectors to tie it in, but given the short, straight runs, I figured the inside corner fittings would be the best bet. She is, literally, working single hand on this, so a bender was not really an option, especially for one small job.

I always try to recommend ways that are up to code and look good (looks go a long ways with inspectors and prospective future buyers of your house) since it needs to work well, and for a long time, and someday, the place will be sold, and when that happens, you don't want a home inspector gigging you on non-code items.

She's done with it, it works, everyone is happy, and now she can plug in the trouble light or shop vac without an extension cord.
