[quote="BobAjob2"]Might be a daft question this one, but, can I rig up an outside light, just drill through the wall, feed cable through, fit a 3 pin plug and leave it plugged into an existing socket?[/quote]
IF u look at implications of part p for outdoor work and
register with labc.
There are two regulations to check Part P and Part L there is a link in projects to Part P and from that you should also find Part L.
I think you are OK with Part P mounting on the wall like you say but worth checking and I think Part L limits size and switching methods think has to be less than 150 watt and needs some method to stop it running 24/7 but don’t know off hand limitations.
Electrical I see no problem.
Bobajob2 - Any circuit that runs outdoors should be protected via an RCD as described within the regs. You can run the light from a socket but I would suggest the socket is changed to an RCD version or you purchase an RCD trip plug and plug your 3 pin plug in that way. To over come the issue of wasting energy and ensuring it is not on 24/7 perhaps a photocell or IR unit can be incorporated as a switching device.
Androo - The reason your outside light is not powering up is simple there is no neutral or complete circuit for it to work. Whilst a light switch may have a red and black or possibly a brown and blue cable going to two terminals these are not Live and Neutral. One is Live (Common) and the other your Switched Live (L1). By jumpering from the two on the rear of the switch (I assume that is what you are doing) there is no neutral and hence an incomplete circuit. The reason why it works from a 13a plug is becuase you are connecting one cable to the neutral and one to the live and if outside I would imagine an earth too. This forms a circuit and hence your light illuminates.
My apologies for not responding earlier. Many thanks for the replies.
Problem is, trying to get a nuetral wire to the light switch. There is nothing reasonable accessible. I think my solution is, to put a plug on the cable and do it that way. Not as neat a job. But at least I'll have the light working.... :cry:
