Hi all,
I am currently in the process of replacing an old timber garage which was there when we moved in. The old garage had electrics in as follows:
Mains - 20a mcb/rcd from house consumer unit, radial 2.5 twin and earth, this connects to armoured cable in a junction box under the downstairs bathroom then goes outside underground around 4m to the front of the garage.
Lights - 6a mcb same as the mains with 1.5 twin and earth, then armoured etc.
When the armoured cables entered the old garage it went to a junction box without any mcbs or anything then onto a single double socket for the mains and single light for the lights in standard cables.
I plan on restoring an old mini in the new garage and I would like to have quite a few lights (kitchen strobe jobbies) for good visability all switched individually so i can use only what i need at the time and around 6 double power outlets for ease although i doubt I will use them all at once. I will however be using some power tools like a mig welder and grinder etc and will also have an old pc out there for research purposes . Also I would like to put in an electric panel heater of some kind for the cold evenings. Garage will be 6mx3m internal and i will need a heater capable of heating that. So I have a couple of questions:
1) Should there be rcd/mcb's inside the garage as well as on the consumer unit?
2) Can electric panel heaters be run off the mains circuit or do i need a seperate circuit for this? if so would it be radial or ring and which mcb/cabling size?
3) Would it be better to put in a second cable and make the radial mains circuit a ring circuit with a 32a?
Thanks for any help
