One for the electricians on here.
I need a consumer unit for my garage, I think I heard the electric was going to run a 10a cable to it.
Question is what kind of unit am I looking for? Been looking online but there's so many to choose from, I reckon it'll be running 2 circuits.

Is it worth trying my local city electrical factors? Never used them before, Think i'll pay them a visit.

Ask the electrician that is going to wire it up is probably the best move

Shouldnt need anymore than two circuits in a standard garage, I take its coming off an RCD protected way from the house DB? As you cant have 2 RCDs on one circuit.
10A supply? Hmm... seems a little low, id imagine the spark is running atleast a 2.5mm feed in whick would be 16/20A.
Would be easy to trip a 10A supply with some garden equipment + lights on.
Should only need a lighting circuit and a power circuit, why are you getting the consumer unit and not the electrician? he will be able to get it cheaper than you will.
Screwfix is another option.
Will do the job if you have RCD in your house covering garage circuit

im guessing the Garage is going to be fed from a 10A MCB from your main house disboard?
If thats the case, just buy the first link posted above.

The electrician is doing the job with parts liberated shall we say, He works for a big company who have a limited line of stock. He doesn't have a personal trade account as it's through the company account.
My cousin has given me a Wylex board for the house, 10 way I think.
Whilst looking in B&Q for some zone 1 spot lights( impossible task I might add) I stumbled upon a Wylex 6 way unit complete with 80A RCD and 2 MCB's for £40, When I went to the fastlane checkout there was a hand written barcode. Upon typing it in the listing came up as 5 way box for £10, So that's what I paid
I may be wrong about the 10a, Think that's what I heard but my head was cabbaged with all the tech talk

lol! Bargain there then.
10A just seems a little small, although in reality you probably wont be using that much anyway.
But if it was me, id be putting in atleast a 2.5mm 16/20A supply.
Why do you need zone 1 downlights? Very rare to need lighting in zone 1.
Usually just us the bathroom IP 65 rated ones with the sealed glass cover.

Cheers Ash, was well happy with that bargain. Also got 2 doors and casings for £49 from wickes. I've bought 2 sets of bathroom downlights with the frosted glass covers. £12.75 for 4.

You can have more than one on one circuit it's just not necessary

I think you'll find you cant use two 30ma RCDs on the same circuit as there will be no discrimination between the two. The house one would have to be 100ma and the garage one 30ma

The 100ma would have to be time delayed though. When you said you can't have 2 RCD's on the same circuit you were wrong... Hence the face

But you dont use 100ma in houses anymore really, as 17th edition requires the use of 30ma
You generally only find them in old TT systems.

Just because you don't see them often doesn't mean anything. You were the one that mentioned the 100ma RCD not me. We could go on all day here but the point I'm making is that you made a statement that you can't have two RCD's on the same circuit...that is wrong matter what the circumstances as you can fit different rating units to compensate for discrimination.
In my house I have the garage running off a 10 way split load board 30ma RCD. I have a two way board in the garage with a 30ma RCD main switch. It doesn't matter which RCD trips first as long as one does! The ideal situation is to have the garage MCB in the board as an RCBO but I just haven't got around to doing it.
BTW I'm not looking for an argument here fella it's just what I've learnt upto now. The not fitting two RCD's in one circuit comes dom the days when they had no proper tolerences etc etc as far as I know.
