Can anyone advise which main switch details I should be putting on an installation certificate when I take an armoured feed from an MCB in a house CU and connect it to a new smaller CU in an outbuilding? In this example the outbuilding CU is fed via a 4mm 2 core and earth armoured supply off a 32A breaker in the house CU and there is a 63A 30ma RCD main switch in the outbuilding CU.
The cert asks for main switch type, rating, supply conductors CSA.
Am I to put the details for the house CU or the outbuilding CU?
