Wiring Diagram

HI

I want to set up a very small switch panel in my garage (just for practice). I am looking to have 4 rocker switches, (1 for lights, 1 for a 2 way power socket + 2 spare), with the main power coming from the house.

Is there a suitable diagram somewhere that someone could point me in the direction of?

Thanks

If you are having to ask then you should not be playing with it

You don't run lights and power from the same cable unless its an extension cable and you are using an inspection light.

If the garage is not connected to the house then you need armoured cable from the house fuse box to the garage FUSE BOX and then sort the lights and power from that.

If the garage is part of the house then you need to find a suitable LIGHTING circuit to connect into and then sort out extending the RING MAIN for your power sockets. Don't run lights from a ring main.

ELECTRICITY IS DANGEROUS and can kill.

Collins Book of DIY has the sort of thing you are looking for.

I think you will find it is now illegal to do what you are proposing unless you are a qualified electrician..

I would think the correct way that it should be done is a supply (from the meter) to a "garage consumer unit" which has its own RCD an mcbs to provide a 16A circuit for the power sockets and a 6A one for lights

Adding any new circuits to an existing system requires Part P certification under the Building Regs and knowledge of IEE 7th edition regs and so should not be attempted by a DIYer. Get someone who is qualified.

Strictly speaking, you can submit a building notice to your local council, who should charge only their usual building notice fee and arrange any inspections they deem necessary.

In practice, most councils will either charge you an extra fee for inspection, or insist you arrange and pay for an electrician to do it, in defiance of guidance from central government saying that they must not do either of these things.

In further practice, the vast majority of DIYers do not notify, and Building Control departments (who didn't want to be saddled with this extra work in the first place) don't go looking for things that would only upset them

Whatever you think of the bureaucracy-related regulations, the technical regulations should always be followed, and if you don't know what you're doing then you shouldn't do it.

AFAIR you do not have to be ‘qualified’ but you do have to be ‘competent’ to design and carry out this work. It will have to be inspected by a qualified person though as it is new work.

Are you ‘competent’?

Ask yourself the following – if you can answer most of it then go ahead……

How is your CPC to be taken to the garage? Is your existing system TNS, TNCS (PME) or will you have to TT it ? Does your DNO know ?
Ideally a SWA and exported MET would need a M/C DB to hold your CPDs – should these be RCDs or RCBOs? Or even RCCBOs ?
No JBs is preferable – you could get away with an FCU for the lighting and consider the IP rating of your outlets in a garage.

If FUD takes over (fear, uncertainty and doubt) then rather than your LABC checking it out (see above) you could hire in a NICEIC or ELECTSA type bod to do it for you……..

Good luck…..
