Wiring into garage advice.

[Mike Wood]

Hi guys.. after a bit of electrician advice

So I am after turning my garage into a workshop and need some extra power.

The garage is attached to the house.

There is approx 2m distance from house consumer unit to garage consumer unit.

I will need to increase the size of the consumer unit and have been looking at a 6 way metal rcd unit.

The cable to the house consumer unit will need replacing and maybe the house rsbo to a higher amp.

I most likely will require a 32 amp socket and also one rated to 16 amps

I want to use a welder without tripping the system.

I also want to be able to use a tumble dryer and a washer together.

So my questions are..

1.. what thickness of wire to connect house to garage I was thinking 16mm

2.. what amp fuse in the house consumer unit connecting to to the garage consumer unit.

3.. any reccondations for the mcbs in the metal garage consumer box. Was thinking 2x 6a 2x 32 2x 40.

4.. I am going to buy the parts and get a spark to fit them.. what kind of labour cost do you think I should expect...

Many thanks

Mike

Firstly you need to know/state the houses main fuse rating this could be 60/80/100amps or higher depending what your supplier has fitted.

Personally I'd be looking to fit a 10mm supply cable, 2 x 32 amp, 2 x 16 amp and lighting circuits as a basic system.

It all depends on what the overall power requirements are for your household/workshop are?

You will probably find that u only have 16mm coming into the house. Some old houses might only have 10mm.

Tends to be fairly new house with 25mm incoming.

Why buy parts and get a sparks to fit them? Just let the sparks buy what is required as they will know what is required for your needs and most likey have a trade account anyway.

Good point re not buying stuff for spark.

Anyone have an idea what I woukd be looking at for installing the above and them supplying mats etc.

Just to give me a rough idea so Im not getting ripped off.

Thanks

would you directly wire the welder to a 32 amp commando plug / socket or is 16 amp enough - Welder is 160+ amp
