Can anyone tell me what the exact safety implications are, with having a 6mm cable protected by a 50a MCB?
I realise the cable will be overloaded before the MCB trips @ a constant overcurrent, but due to a dead short fault, the MCB would trip immediately.
Exactly what kind of fault would draw enough current to overload the cable, but not fire the trip?
Should I be worried about it?
