Hello
Im looking at adding electricity to my garage. The armoured cable is already in place but its just connected to a 16amp Circuit breaker in the house CU and then just a plug socket in the the garage.
I understand thats not right so I was planning
1. Placing a 2 gang CU with 40A 30mA RCD in the garage with a 20 or 25amp MCB for the 1 double socket
2. A 6amp MCB for the 1 light
I was going to put this into a 32 amp MCB in the consumer unit in the house where the feed is coming from.
The question is would this be ok or should I be using a smaller MCB in the house CU and the Garage consumer uint. I didn't want to put a 32 amp in the garage as the socket will be a radial circuit and not a ring and as its only going to be powering a tumble dryer I didn't want to add a 32amp mcb as this seems to High and would never trip if a fault was found on this kind of circuit.
My other option would be
taking a feed from the house consumer unit via a 16, 20 or 25 amp MCB via the armoured cable to the garage then into a metal socket that has an RCD and then from the socket to a fused spur to power a light. That way missing out the need for a CU in the garage.
Please can you give me your options, I really need help with what size MCB's need to be used in the house and garage.
Thanks for you help
