Markinstin Posted April 19, 2007 Report Share Posted April 19, 2007 GFCI receptacles are one of 2 legal (code) ways of replacing receptacles in a 2 wire system #1 is a 2 wire receptacle (never to be used in wet locations) #2 is a GFCI ok now you know the way a gfci works is simple it measures the current flow in and out on the hot and neutral if it is different it trips so if some voltage is drained off to another grounding point the GFCI trips easy right just an electrical teeter totter.

The NEC specifically allows it in 406.3(D)(3) - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
