Hi,
I've just had a shed built and the builder has run the lighting for the shed off the power circuit that he fed in there. The power circuit looks fine - essentially an extension of the power circuit in the utility room. The shed has been built onto the utility room.
I expressed concern, but the builder has assured me that it is perfectly fine to power a light off a power circuit. Is he right?
many thanks in advance.
Possibly no problem for him electricky-wise - but if your electric tool slips, does you some damage and trips the breaker you will be left in the dark...

Well if it isn't I'd better unplug all my desk lamps and the like...
I think the issue with lighting circuits being 'done different' is that the loads are fairly predictable, and the requirements for safety are somewhat less than a ring main. Hence light duty cable ad 6A fused radial not ring..
The message from "JavaEnquirer" contains these words:
Yes, provided it's taken through a fused wossname as the 6A cable for the lighting circuit won't be sufficiently protected by whatever's protecting the socket circuit.

Without looking up the precise details, if the circuit that supplies the sockets has a protective device rated at more than ISTR 16A then some types of lamp holder cannot be used (and if you have some types of lamp holder it must be less than that).
The cabling to the light should be protected by a suitable protective device, usually a fused connection unit from which the lighting is taken.
If the shed is used for more than just lobbing the lawnmower in then the power supply should be direct from your consumer unit, with a small consumer unit in the shed for lighting, socket outlets and whatever. This is to try and avoid you plunging yourself into darkness when you drill through a cable.
For storage space only it doesnt matter, but if youre likely to use power tools there I would object, as you'll be plunged into farkness the moment your tool develops a dangerous fault, and is doing 20,000 rpm.
PS what is farkness? Well, its like darkness only far darker. Its when you really can not see a single thing anywhere. Unlike ordinary darkness, when there are lights on in other rooms and you can see just about.

At Highgrove House, I would imagine.
