Garage Heater Install
Garage has a Square D QO panel with 100 amp main breaker. Heater is 240 volt, 30 amps with a NEMA #6-30P cord.
I plan to use a 1" nipple to a single gang steel box directly under panel. Anything special I need to do here?
Heater just arrived and the plug is huge. Will the receptacle fit in a single box or do I need to get a 4" one?
Thanks

I just talked to my brother and he did the same thing for his compressor. Instead of a nipple he used a clamp inside the box and put the nut inside the panel, never thought of that.
Is that legal?

Attaching receptacles to a panel using a nipple is done all the time, no problem. If panel is surface mounted you can use an off set nipple if need so the receptacle box can be fastened to the wall. If the heater came with a cord set then it is intended to be plugged in.

Use a 4x4 deep box and a taylor cover if you wish to avoid a lot of swearing.

One Last Question
With a metal box you need a ground jumper to the screw in the back of the box. Is that necessary with this receptacle?
I think I've lucked out. For the plug to hang properly I'll have to mount the receptacle upside down (ground up) which means the holes for the wires will be facing up, towards the panel. Perfect.

You can also get covers that have 4 screws in them for a little extra support.
All taylor covers are designed that way, device attaches to the plate and the plate attaches to the box.

Normally the receptacle attaches to the cover plate not the box.

Yes, I can find all kinds of covers with 4 screws but I'll be damned if I can find one box that will accept 4 corner screws. All the boxes I've found have two places for corner screws.
Thanks guys, I have to get off this machine before I go blind.

Ok I understand your question now.
Your cover has 4 holes so it can fit on your box properly no matter how the box is rotated.
Look at your cover and envision only two holes on it, now envision the box being rotated so the screws are opposite to where they are sitting. Your cover would no longer fit to keep the device aligned properly.
2 screws is all it takes to mount something on a 4x4 box.
