I am working on a project where we have installed 277volt lights to back light several mirrors located at sinks in a locker room. The light fixtures are behind the mirrors and someone standing at the sink could eaisly place their hand behind the mirror and come in contact with the light fixture. The e.e.on the project says all we need to do is put a plastic lens over the opening to prevent contact with the fixture which is only 8 inches above the sink. I say we need GFCI protection and a lens,although I was told there is no 277v .GFCI breaker available for the panels we have on the project. Am I right or wrong ?
