In Reply to: Hospital receptacle GFCI vs. Dead-front spec GFCI... posted by Neuro on September 17, 2008 at 16:34:24:
There is no internal difference between regular GFCI receptacles and the dead-front ones. The dead-front ones just cover up the plug contacts. Internally, all of the GFCIs, regardless of manufacturer are basically the same -- I've seen the insides -- thin circuit board traces carrying the load current, puny contacts in both poles of the GFCI mechanism, ferrous parts in the wire clamps. I used to have old pictures I took of the insides of a GFCI receptacle somewhere on my PC. If I find them I will post a follow up.I installed dead-front GFCIs in my first DIY balanced power project. By my first revision, they were out. Now I don't use them and just exercise greater care with balanced power. I've looked into earth leakage circuit breakers by Carlingswitch as a possible alternative but they have been impossible to find in-stock anywhere online.
