    I thought an MCCB was the same as a MCB (actrually CB not MCB as everyone calls them) only for higher Amps, over 63A

    Trip faster? Does the MCCB not have to trip within 0.4s ?

    An MCCB is not needed as the design current is not greater than 63A per phase.

    The cable from the main board was already there, so was the meter before the sub board.

    The supply company feeds a meter, then it goes to the 1st board which feeds 4 sub boards, there is a meter before each sub board. The 4 sub boards are protected by 63A 3 pole CB's.

    I did suggest that kit to the customer before I started. He said he wanted to use the meter he already had. What does CCC stand for, I do not know what the abbreviations you lot use. Is it Cable Capacity Chart?

    This is a secondary board. This is a private meter just for this building. Mains supply branches off to 5 buildings, each with a private meter so the landlord can meter each building separately
