Re: 240 volt outlet > 120 volt?

Sounds like what you really need to do is to remove the current 240 volt circuit and replace it with a feed to a subpanel, then wire the 240V and 120V crcuits you need in the garage from the subpanel. That wouldn't use any additional slots in the main panel and would address all the needs in the garage.

There are several steps to doing this right, all well-documented in the archives here. Whether to do it yourself or hire a pro depends on your level of experience and comfort with electrical work, the rules in your area, and perhaps the willingness of the local inspector to work with you.

I must say I wouldn't recommend it, but as long as it is in conduit with the conductors are run together it is not a violation and would work.

lack of slots is not a problem anymore. go out and buy a minibreaker that will have TWO breakers that fit in ONE slot. thereby you have an open slot.

I am not an electrician by any means. But I do know enough that if those here who ARE same are advising against something that they have good reasons and I'd follow their advice.

Zeez, no on the diagram. You are placing a 120V recpt on a 30A breaker which is not allowed.

3phase, I think he said it was a 20-amp breaker.

Yes, that would be two different 120v circuits each with a 20 amp breaker. What's so wrong with the diagram if it meets code? I looked in the 240v box last night, I think they ran the 4th cable to it and just capped it off...making it even esier to do it this way.

I think what's making everybody a bit nervous is that this is unusual. But, done properly, I think it would be safe and not violate any codes.

Well, I think I'm going to try it then. As long as it doesn't violate any codes I'm happy. This would give me 240 and 120 at the same time, right?
