[QUOTE="gordon mcgregor, post: 31228, member: 169"] Re: L5-30 wire for 220V? I find reading about the electrical codes etc in the US fascinating the variety of connectors and wiring possibilities. I know in indutrial premises similar connections to the ones you describe here were available but they tended to be hard wired or used a device specific plug.
