    Disconnection time extended to 63 amp circuits

    Does anyone know why the 0.8 and 0.4 second disconnection time requirements are now extended from 32 amp circuits to 63 amp receptacle circuits? Is this because the supply sources are getting stronger?

    Disconnection Time for IT system

    What is the max disconnection time for an IT system? I think it would be shorter in that an MCB would only be triggered after a fault on two individual circuits hence double the loop impedance?
