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.

Also, please read about Part P in the Wiki section
