50 amp 220v concession trailer service question
Hello, my name is Mike Riordan, owner of Riordan & Sons Electrical Services. I have been asked to provide a 50 amp 220 volt 4 wire circuit and receptacle for a concession trailer, for an annual fundraiser festival that benefits a local hospital and library. My question is, is there a standard configuration for a 50 amp 220 volt shoreline? If anyone could provide a Nema # , photo, and/or good description of the shoreline plug, that would be all i need. Thanks in advance, your time is appreciated.
