Help hooking up an evseupgrade L6-30 Receptacle and Breaker

[Lasareath]

Thanks for the below tips, they will help. I try to research as much as possible, get the things I need and run it by my neighbor, he is a really nice guy and will do everything for me and I'd rather just use him for the things I'm not sure of. He will tell me if I'm doing something wrong.

Here is another project he helped me with almost two years ago and the house is still standing (knock on wood!!!). LOL

Guidelines for a professional install (not necessarily complete!):

0. Pull permit from local jurisdiction.
1. The L6-30 receptacle you linked to is fine. I would mount it in a metal box with metal faceplate. I would personally use a 4x4 box for the extra room.
2. You should be using 10 GA wire for a 30A circuit. You can use NM-B (aka romex) which you can get with 2 HOTs and a ground. It will be called "10-2 NM-B". The 10 is the wire gauge, 2 is number of current carrying conductors. It will have an appropriately sized ground (10 GA in this case). Note that if the romex will not be covered by drywall, you can not use it. Romex is only rated for use where people are not able to touch it. In which cause you must use conduit and individually stranded wire.
3. Make sure your metal box is grounded.
4. You will need a double pole 30A circuit breaker appropriate for your panel. I hope it goes without saying that you should cut power to the panel before working on it!
5. Get work inspected by your local inspector.

How would you Ground the metal box?

Wouldn't it be better to buy a spool of 10/3 NMB romex, so then I'll have an extra conductor that can be used to ground the metal box?

3. Make sure your metal box is grounded.

How would you Ground the metal box?

With a grounding screw or lug and the ground wire.

No. The neutral wire should never be used as a ground.

I tend to ground metal boxes by screwing the receptacle into it. The ground connector on the receptacle is also tied to the frame (metal portion) of the receptacle. Drees, wouldn't you agree?

[Lasareath]

So I actually don't need to perform any additional steps because out of the 3 conductors one is a ground wire and if I have a metal box then the receptacle will ground the metal box when the receptacle is screwed down?

Is that correct?

As drees said,

It will be called "10-2 NM-B". The 10 is the wire gauge, 2 is number of current carrying conductors. It will have an appropriately sized ground (10 GA in this case).

In other words, 10-2 has two wires encased in insulating plastic, plus a third bare wire, which is the ground.

I am still concerned about this statement you made:

Their main panel is in the garage right next to the garage door and I'll only need a few feet of cable.

As drees also said, "romex" can only be used where it is covered, and garages often have exposed studs on the walls. Will the romex be covered by drywall? If not, you should use some sort of conduit. I would probably use LiquidTite for a short run. And if you do that, you can run individual wires through it instead of using romex.

No concern needed. The garages in NJ must use sheetrock by code. My gang box will be mounted recessed into the sheetrock. I'm in IT for 25 years. I run CAT6, Coax, HMDI, Stereo cables for a living. I have the tools, knowledge and experience to run the 12' of 10/2 wire in the wall hidden away behind sheetrock.

I will post all steps of this procedure in this thread. Most likely I will begin around 1/15/14

Thanks!

No, that is not sufficient.

Just Google "proper ground metal box" images and you'll see a dozen examples of proper grounding.

I've grounded metal gang boxes before as shown in these first two pictures, I've never used those rigid conduit ground clips shown on the last picture;
