MegaSack DRAW - This year's winner is user - rgwb
We will be in touch
I am thinking about putting a small flatscreen tv on the wall in our kitchen and bringing a feed from the Sky+ box next door (easy to do I reckon - assuming you can output more than one feed from the box using the same channel of course). The thing is we don't have any power near to where I want to site it apart from a blanked off old lighting circuit switch. Assuming the electrician didn't disable the power to it completely when we had some work done last year, would it be okay to take a power feed from it for a small (14 inch or something) LCD monitor? I can't contact the electrician as he met someone, found god and doesn't do leccy work any more and doesn't answer his phone.
it would work OK, but if you use a normal socket, someone might subsequently plug in a kettle or an iron, and if the fusing at the consumer unit weren't right the wires could overheat.
You can't fit a socket on a lighting circuit, basically for the reasons mentioned above. However, you might be able to fit a fused connection unit (fused spur in layman's terms) with the TV hard-wired into it and protected by no more than a 5A, and preferably a 3A fuse. You'd need to ensure that the circuit loading with TV and lights on doesn't exceed the circuit fuse/breaker rating, which is generally 5 or 6A for a lighting circuit. This assumes you have live, neutral and earth at the switch point - it might be just a live and a switched live, in which case you're buggered.
And not forgetting electrical work in a kitchen is notifiable to your local authority building control under Part P! 😉
The Sky+ box has a second RF outlet that you have to enable from the service menu. Add a "magic eye" and you can change channels too.
What Dudie says makes sense. DON'T fit a plug/socket to the lighting circuit.
Don't know the construction/layout of your house but it's not generally too hard to fit a fused spur in the right place off the main circuit and drop it down in the wall cavity etc.
Is there a power socket on the other side of the wall? If so you could drill through the wall and take a spur from that.
There's no power nearby ( other side of a door on one side, window the other). I wasn't thinking of fitting a socket - it would be something like as you have all described. I guess I need to get an electrician in to look at it really. Cheers 🙂
