Flukey, maybe a little off subject and a daft question but it seems you(me) seem to doubt yourself when under assessment so the question is;
when filling out the DEIIC on the schedule of test results, if you have a garage supply from the main CU say circuit 5 or whatever, and that cable supplys a small 4 module CU in the garge which has two circuits, lights and sockets, do you treat these circuits within the garage seperate or part of the readings for the garage supply cable?? hope this makes sense! and if you treat the garage circuits seperate where do you put them on the certicate, after the rest of the main CU circuits have been listed? leave a space and put them at the bottom?
Cheers
