Re: Need help idetifying a circuit
said by robbin:I agree, it looks like it was put in for a dryer or welder at some point. It's definitely 240V, either 30 or 40A.
I bet it's a 240v circuit which was never hooked up. Put in for the future welder or table saw. If so, it should be easy enough to make it usable.
