hmm - till the next owner plugs something else into the socket ?

I agree that a socket on a spur from a lighting circuit could possibly be used for something else by a homeowner without realising.

But the 3amp fuse would go if too great a load was placed on the circuit. If the homeowner inserted a higher rating fuse, The circuit is protected at the fuse/board consumer unit.

The 1.5mm twin and earth cable used commonly in lighting circuits is rated to 13amp (depending on how it is used, under loft insulation/ through conduit) So the homeowner would have to plug something in the region of 3000 Watts to pose a risk to the cable.

If someone did replace the 3amp fuse with a larger say 13amp fuse, they would probably pose a simular danger changing a blown fuse anywhere in the house, Plugs, lighting spurs from sockets ect. So is it best in that case to stop homeowners changing fuses??

Nothing wong with running a spur off a bedroom light as long as you protect it with a 3 amp fuse.

NOTHING WRONG..there is some called a disconnection time to take into account...

i have been taught that it is VERY bad practise to spur of off any lighting circuit thats even before we start about any air bourne interference thay might be floating arround

thank god someone with aleast a little sense

You Obviously should never spur a socket off a lighting circuit and you should always try and get your alarm supply via an unswitched fused spur off a ring main. Unless the feed goes directly to the consumer unit then even better. Spurs off lighting circuits are normally seen for extractor fans, door bells and sometimes tv amps. This would lead you to believe spuring for an alarm supply in this way would be acceptable but occasionally when light bulbs blow sometimes they can trip or blow fuses and can cause customers grief with the alarm. Just never do it is the best way.
