Yes
I have just had a garage build with a custom fit electric roller shutter door.
I am just working out the electrics and plan on running the door on its own circuit from the consumer unit with one socket also in this garage for any minor needs (battery charger jet washer etc.) I was planning on a 10amp circuit breaker in the consumer unit.
 
Surely the manufacturer do the door gives some idea of the required size of wiring for the door. Or at the very least the current it will draw.

I will be calling them on monday they are shut weekends just trying to get an idea.

Install info suggests only 3amps that seems a bit low.

Yep thats pretty much it.
I will clarify with the company on monday.

I am going to run the door and socket on a 10amp rcd circuit and the light on a 5 amp rcd circuit.
 
Good practice would be to run a 15 amp supply from your main house consumer unit to a consumer unit in the garage. You can then run your 5 amp lighting circuit from this and the supply to the garage door and sockets. Also, most electric garage doors are supplied with a standard plug and the fuse in this would indicate what the current draw is. But a 3 amp fused supply sounds about right.

I allready have another consumer unit that is like that in the celler which is very close to the garage so I have loads of spare capacity on that.
 
My Chamberlain 850 which opens and closes a heavy steel double garage door is 125 watt at 240 volts which gives a current usage of just over 0.5 amps.
 
Mine is protected by a 3 amp fuse.
No point in going over the top :)

If you don't know then don't guess, get someone to do the job properly and get it done to the regs.

Well John, you could at least give him the formula !! ;)
Which is of course : I = W/V or Current equals Watts divided by Volts.

About the same as 4 light bulbs (OK, lamps for the pedants!)
 
If you're going to put a socket in as well, you need to have a big enough breaker and cable to handle it's potential maximum load, eg 13amps (or double if it's a two gang). You say you'll only be using it for low wattage stuff, but it must be able to handle the max load. If you sold the property on for instance, somebody else wouldn't know it's only for low power items only. Potentially it would be a fire hazard. (I presume you're having the work done by a proper sparky btw? They wouldn't install anything that wasn't up to the job anyway).

If it's a new circuit going in, I have a feeling it needs to be signed off by a proper sparky (with the required certification [scrub that, any berk with the right certification can sign it off, good sparky or not!]) before it's legit.

A competent and registered person can do the work and provide the certificate.

Alternatively, you can do it yourself if you notify building control that you are going to do it and have them inspect it.

The fees involved would probably make it cheaper to employ someone to do it though!

Well Paul, have you managed to set fire to your house or electrocute yourself yet ? :runaway:
An update would be nice; if you can still type that is !! :eek:
 
All going well have just got to finsih and connect back to consumer unit tomorrow.
