Hi there
we've just got a new concrete garage built - 40sqm, situated about
10m from the house and around 15m from our consumer unit.

I would like to run mains to this garage, to supply lighting and light
power. I only intend this to be for 'domestic DIY' power, no plant
machinery or anything like that.

I'm competent in actually doing the wiring but a little rusty on
modern practice. My plan #1 is to run a new circuit of 4mm 3core
armoured cable to the garage, then fit a 2-way consumer unit and run
lighting and power off that.

Quick question - is this feasible/sensible? & if not, can anyone
suggest a better alternative?

Thanks for any suggestions

Sounds reasonable - It would be a good idea to fit an RCD on the garage
socket supply (not the
lights - you don't want them going out when you jigsaw through the
cable..!).
Garage supply should have its own MCB in the main house CU

If you can make it sub-main supply from the house with its own switch gear,
then you'll stop any nuisance tripping of the circuits in the house.

It is easily done with use of Henley blocks (16mm Terminal block) to split
the tails from your meter to another single way consumer unit dedicated to
the garage supply.

I would also advise you, if using an RCD, to make a separate earth point
from the consumer unit in the garage and on to a ground spike at the garage
end of the new supply.
