I’ve recently come to understand that the 30mA Ground-Fault protectors, often built into a circuit breaker, is intended to protect the Protective Earth (Safety Ground) circuit in the case of a short circuit (opening the circuit before the safety ground could be damaged. It this correct?
Here is my question. I’m evaluating a cut-off saw (5hp) which uses water to keep the blade and material cool. The manufacturer uses a 3-phase supplementary circuit breaker which includes the 30mA GFPE option. This is a very expensive part. When I asked them why they use the GFPE part, they couldn’t give me a good answer. Would such a part be required on a 3-phase motor driven cutoff saw in either North America or Europe? What standard would dictate this? If the only purpose of a GFPE is to protect the Ground Circuit, on products that can handle shorts without damaging the ground circuit, would a GFPE still be necessary? Where are GFPE typically used? What industry? Please educate me. This is a new one on me.
