Doing an ECIR and have a 3 phase supply circuit to a machine on a type C breaker but loop reading is .50 and max acceptable by the regs is .35 I can’t really change the mcb to a type B as the start up current will most likely trip it, what are my options, increase the cable size perhaps?
Sorry ECIR
Still got it wrong EICR
