Spa Panel Wiring, help with ground

thefost · Sep 3, 2016

Trying to figure out how to wire my 220V spa panel and could use some help

I'm going to be using the wiring from my stovetop which is only 3 wire (hot hot neutral). There is no ground wire.

My control box already has a few working 120V outlet connections that have ground, completley separate from the 220V spa panel that I'm adding. Should I just use the ground from the 120V outlet to finish the wiring of my 220V spa panel?

If your 120 volt outlets have a good ground with a ground wire going back to the main panel, you are golden ! But I would suggest that you get one of those little plug in ground testers and make sure you have a good ground.

Sounds like the time to call an electrician. Your stove outlet is generally required by code to be dedicated. ie nothing else can be on it. (All codes are local, but I doubt its allowable anywhere in the US)

Ground comes from the ground... literally. You can purchase a ground rod and drive it in yourself. If you want to DIY you may need to read up on code.

If not call an electrician!

Maybe the OP unplugs the stove then plugs in his Spa panel? That's a dedicated circuit.
Nothing wrong with that.

In older installations, the Neutral doubled as ground. Then the code was changed and the Ground needs to be a separate wire, although both Ground and Neutral meet again on the same bus in the service panel.

To operate the Spa panel's GFCI there needs to be a dedicated ground connection, which could be "borrowed" from one of your 120V connections in your control panel.
