We have a 30 amp outlet in our garage. If we use our surge protector, won't that tell us if the voltage is too high?
What you probably have is a 220v outlet for a welder. Best thing to do is check it with a voltmeter before plugging any sort of device into it.
I don't think I'd stick my cheap volt meter into a potential 30A 240V circuit, I'll let a pro with a properly protected Fluke handle that. If I still had access to the Fluke from work I might do it myself but I've seen what happens when a cheap meter explodes (thanks youtube!) and I don't want to be anywhere near that kind of plastic shrapnel bomb or the potential for flash burns.
