Went to my Parents house yesterday and checked out their electrical panel, it's a Square D QO just like what I have at home.

There is room to add a 2 pole 30A breaker. there are two in there right now for the air conditioner and something else.

The Leviton Receptacle should be here tomorrow, I just need to start, I think I have some free time Friday.

(I know somebody is going to post that the total amps on the breakers is more than 200A but I'm not interested. Don't waste your time. If I add up mine it's the same way. In 5 years I've never blown my main breaker. So I never use more than 100A at the same time. The only breaker I ever blow is one in the kitchen that runs my coffee machine and microwave. That's it. One day I'll run a new circuit for just the microwave oven.)

I need a 2 Pole 30A breaker like this one: should be around $15

My understanding is that it's OK if the individual breakers add up to more than the service. Load calculations are more complex than that, and take into account whether loads are likely to be used at the same time, and how much the actual equipment will draw, not just the circuit breaker size.

Yeah, my wife is an Electrical designer at a MEP firm in NYC, I was just about to ask her that question on how she sizes her circuits and panels.

Got all the supplies I need. Just waiting for some nice weather. It's been too cold and my Parents are not even in the state anymore, they are at their vacation home for 4 months in Florida, So I'm not really going to their house so why install the circuit if I'm not going to be using it?

They'll be home by April and weather will be so much nicer to work in an open garage with no electricity on.

Just one question; the 10 Gauge wire is really thick, can I successfully screw down the ground wire with a green ground screw as pictured?

Or should use that all copper terminal lug to attach the ground wire to the Metal gang box?

I have those grounding clips too but the slot where the ground wire is supposed to pass through looks too thin.

Yes, The receptacle has a Ground screw.

The Metal box needs to be grounded as well.

So the ground wire coming from the Electric Panel needs to be secured to the Metal box and that same ground wire needs to be secured to the L6-30 Receptacle.

Please see the following video:



So my original question asks is the grounding screw large enough to successfully hold down a 10 Gauge wire, If not should I use another mechanism to secure the ground wire to metal box?
