I am wiring a refrigerated storage building. It has heat tape incorporated on one of the drain lines. In order to supply a means of disconnect, I am planning on putting a plug on it and installing a receptacle. The problem is that the heat tape only has two wires ( no equipment ground ) Do I put a two wire plug and an ungrounded receptacle, or a 3 wire plug and 3 wire receptacle, even though it has no equipment ground???? Haven't talked to the inspector yet, and thought I would get some opinions, just in case I didn't catch him before he left his office in the morning..
Also does anyone know a code reference for the installation procedures inside a freezer. Is it considered a wet location?? Looks like it would only be if the compressors failed. I am mounting weatherproof boxes, but what kind of cover do you think you would put on this receptacle I am putting for the heat tape?? An in use cover maybe?? Thanks for the input...
