I am making a toolbox control panel, a combination 110/220v for two brew setups. I am going to make the input removable. I got an outlet from work, four prong, nema L15-30-R. I know this is 3 phase, but can I wire and use it for 240 single phase? Two hot leads, neutral, and ground. Leads are marked X Y Z and ground. Any advice would be greatly appreciated.
