I have a twin fluorescent fitting wired in but I'd like to control each tube with a different switch. (actually I have a few of these double fittings - and I want one switch to control say the left hand tubes and another switch to control the right hand tubes). Looking inside we have...

Hi. Just wondering what is a safe MCB rating for the setup I've currently got on my garage. In house consumer unit is new & currently has a 40A MCB (non-RCD) protecting the 6mm supply to the garage. In garage, there is a second mini consumer unit (RCD protected) supplying two circuits...

Hi, Wondering if anyone can suggest how to calculate what can be fitted to an existing circuit. Its a 6A B6 MCB running 1.5mm t&E to the light fittings. How many 1800mm 70w tubes can I expect to run without the MCB popping / overloading the cicuit? I was hoping for up to 10! Are...

Hi, Just wanted to know if there are any adverse side effects of fitting a radiator which is technically too big for the room? Ie if it is in a loop, would having a big beast in this room controlled by a thermostat valve mean that this room gets to temp too quickly then the valve shuts off...

I've just disconnected a couple of wall lights in my upstairs bedroom and re-routed the wiring from up in the loft down through a central rose instead. Should I bother chasing out the old wiring from the walls or just plaster over the ends and leave the rest in situ? Its dead from both...

Just a quickie: Would this be safe to use as a switch for a set (5) of under counter 10W flourescent tubes? http://www.maplin.co.uk/Module.aspx?TabID=1&ModuleNo=2363&doy=4m1 Would switch live panel mounted in an earthed steel box. Soldered & insulated terminals. If not, why not? Thanks!
