Prospective short-circuit current. The hundreds or thousands of amps

It should only flow for a short period before the protective device
operates, but the wiring has to be able to take this current while
it flows if there is not to be further damage to the wiring.

It would actually be more appropriate to measure the Earth Fault Loop
impedance since it is the integrity of the earth that is in question.
