detached garage wiring

[brightspark109]

hello, detached garage wiring.

my plan for this would be to run a 6mm armoured to the garage from the house fuseboard. there are spare ways. there is no extranious bondng to be done no metal pipework etc. garage is brick built and dry.

come off dual rcd board 32a breaker in house, 13m surface run. clipped.

into garage unit.

heres my question?? if i take armoured from existing rcd board do i use a garage unit with rcd as main switch, or do i just get a garage unit with main switch, as rcd protection is from house board???

also i plan to carry out this work in pvc conduit in garage. demand is low. its only for 2 lights and 3 d.so (one for fridge)

using 6mm for futureproof

first check if the CU has the capability of a non-RCD protected way, then if so, RCD at the garage. second option is to split the tails and fit as switch fuse supplying garage. using a RCD protected way in the house CU has the disadvantage of fault in garage takes out half the house.

True, but if it's dry and only for lights and a fridge it's unlikely to cause any issues. If the garage was integral to the house, it wouldn't need its own RCD, so I would apply the same logic here.

Having said that, if the consumer unit is plastic, it might be just as easy to provide a separate switch fuse that the SWA can be glanded into.

If you need RCD protection at the garage end then you fit a metal board with an RCD.
If you don't need RCD protection at the garage end then you fit a metal board with a main switch.
Simples no?

May I ask what qualifications you currently hold?

My answer to your question will depend entirely on your answer to mine.

Thanks buddy

Because the question is so basic it shouldn’t need to be asked by a qualified electrician.
