I'm with the others guys on this. If it has a 3 prongs, then it needs to be plugged into a 3 pronged recepticle. It probably wouldn't be a bad idea if the wall recepticle was a GFCI also. There's also another type of recepticle out now days for surge suppression. I think they are TVSS recepticles. I need to do a little code research to refresh my memory on what the correct name is. I haven't installed any of these yet. I mostly work in an industrial enviroment.


BTW, LLE here also
