MCB and Cable Advise

[grettonman]

I want to install a consumer unit in a Garage fed from the main Consumer Unit in the House. The Garage CU will have a 13a power ring, outlet for an immersion heater and a lighting circuit.

What size Cable ? 10 mm
What size MCB on the feed from the House ?

The MCB consumer unit in the Garage is rated at 63 amp.

Bas & Sparks123 will need a lot more information before they can help.

How far away is the garage from the house and what is the immersion heater for? The water supply to the garage could effect your new earthing arrangements.

Please post a picture of your consumer unit, meter and supply cut-out.
