I have been asked to provide a 50 amp 220 volt 4 wire circuit and receptacle for a concession trailer, &nbsp;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.&nbsp; <br> Mike Riordan&nbsp; <br> Riordan &amp; Sons Electrical Services&nbsp; <br> http://www.roadfood.com/Forums/fb.ashx?m=650822Thu, 12 May 2011 22:08:35 GMT
