This may be a dumb question, but I cant find an answer anywhere.
I have a couple a three prong twist-lock plugs and receptacles with a rating of 120v 30A. Can each prong handle 120v? Being that there will never be more than 120v in any wire, Can I do 120v-120v-G for a 240v element? Or does it need to be 120v-N-G? I don't want to melt anything by just trying it out...
