Hello all,
I need some advice wiring in a consumer unit into my garage (with 63A RCD, 2 x 6A MCB and 1 x 32A MCB). I have read the sticky of 'wiring diagrams for lighting circuits' but still need help.
Current Wiring:
An armored cable goes from the house to the garage. It is on the same circuit (30A) as my boiler, extractor fan and a set of twin sockets (previous owners wired it this way. I would rather have boiler on separate circuit). It then runs to the garage where it is wired into a set of sockets in the garage as well as the lighting in the garage (2 lights, 2 switches). Finally, it also powers a single external light which has two switches, one in the house and one on the outside of the garage. As such the armored cable contains, red, black, blue and yellow wires.
The system works but I am changing all the internal lights in the garage to fluorescent battens as well as planning to add a second outdoor light to illuminate the garden in the dark (on the same ring as the other outdoor light).
As the wiring for all this also powers my boiler (annoying) I decided a sensible thing to do would be to wire in a consumer unit in the garage so that I could work on the electrics in the garage without having to turn off my boiler (there's snow outside at the moment). The plan was to wire the armored cable into the consumer unit. The outputs would then be the garage sockets on a 32A MCB, the internal garage lights on a 6A MCB and the outside lights on a second MCB so they could all be worked on or shut off idependently.
So Far:
I've wired the cable from the house into the consumer unit (the red and black wires anyway). The garage sockets are wired in and work, the internal garage lighting is wired in an works.
The Problem:
What I can't work out how to do is wire in the external lighting to run through the consumer unit. I'm sketching out the circuit diagrams but without determining which wire runs from each switch to the lights etc, it will be difficult. If there is a way with the wires I have coming into the garage (red, black, blue, yellow) to wire in the consumer unit to the outside lights, that would be great.
Many thanks in advance.
