DB 1 - Power DB:-
Schedule:
cct 1: (Altar radial sockets) Wired in MICC 1.5mm live & cpc (14th Ed imp 1.29/1.94 21A/26A 1.5mm 25A), 2 points served, B32A fuse.
cct 3: (Organ supply) Wired in PVC cables in metallic trunking, 2.5mm lives, 1.5mm cpc (23A), B32A fuse.
cct 5: (Heating controls) Wired with mixture of PVC (19.5A) and MICC (25A)cables, 1.5mm live & cpc, 9 points served, B20A fuse.
CCCs are assuming ref method C, if not otherwise specified.
So cct1 2 points served? max 26A limited load?
Generally code 2 drop breaker to 20A
Cct2 assuming radial Code 2 drop breaker to 20A, what is the current draw from the organ, if less than 23A cable is protected and does not need overcurrent protection.
Cct 5 was OK with the original MICC but the introduction of PVC means should be 16A breaker code 2.
