Hello,
So we know that GFCIs are people protection and are set to ~5mA of differential current leakage. GFPEs are equipment protection and have varying set points but a common default is 30mA.
My question is how do GFPEs provide equipment protection? How does leakage current to ground damage equipment? How do you determine how much leakage current can damage equipment?
The reason for the above question is that the standard line of GFCI is for people and GFPE is for equipment is repeated constantly, but somehow when starting to discuss GFPE settings, the conversation always comes back to people protection even at these higher values. For example, how does 30mA at local power point GFPE and 100mA at the source for the individual power points at dock installations protecting equipment? Every time they are brought up, it seems to circle back around to ESD (Electrical Shock Drowning).
