I don't think that is the reason recognized in Europe. The PE circuit
has the same (or similar) current-carrying capacity as the line
circuit(s), so its fault-current capacity for 30 s is very large even
for a household supply. I think the protector is there to prevent fire
and to give some protection against electric shock, although the latter
is compromised so as to prevent nuisance-tripping, which would occur if
the trip were set at say 5 mA to give much better protection.

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.
Thanks,
Brian
