GCFI vs grounded
I'm trying to understand the difference between the above. So I read on another forum the following: "A GFCI and a grounded outlet do two different things and protect against two different scenarios, and one is not a replacement for the other. A grounded outlet protects against a short in the WIRING, specifically, a wire coming loose and contacting a metal electrical box or housing. If the box or housing is grounded, the fuse or breaker will blow and presumably you'll realize you have a problem. If this DIDN'T occur, anyone who touched the box or housing would get a shock - whether you've got a GFCI outlet is irrelevant. A GFCI outlet protects against a short (or more commonly a current leakage) involving YOU and an electrical device plugged into the outlet. If an appreciable amount of current flows from the appliance through you to an earth ground (presumably because your hands are wet - typically GFCI outlets are installed near sinks), the outlet trips. So, in the first scenario, the problem usually is a frayed or broken wire, whereas in the second, the problem is carelessness on your part, because you didn't dry your hands."
BUT, if the appliance is plugged in a GCFI and the wires get lose (like in the grounded example above) as the person touches it wouldn't that trip the GCFI because then the current going out of the outlet would be different than the one going back in?
