Sorry Doug, but I don't know anything about wiring in the states and I don't think you'll find many people on here who do, though I might be wrong :?: We don't have wall switches in bathrooms here in the UK, we have either a switch outside the bathroom or a pullcord switch in the bathroom.

From the sound of it, it would be beneficial if you did. If the current wiring is safe, then it's not absolutely necessary; it depends on your situation. I would say it needs rewiring as soon as practicable, rather than immediately because from the sound if it, it doesn't pose an immediate risk...

http://www.era.co.uk/Docs/casestudies/CaseStudyCS0108.pdf That was a fuse no larger than 13A, you can imagine the result if the short-circuit current is larger than 6kA on a distribution circuit for example :shock:

How do you know they are all on a ring? The reason I asked if your kitchen sockets are all on the same circuit is that the 4mm may, at some point, have been used to supply an electric cooker and they've fitted a gas cooker and used the redundant supply to power more sockets. Which means you may...

I can see where the confusion arose. Often recessed light fittings have nowhere to enclose the connections because the are too small, light fittings, ceiling roses, fans and the like are large enough to accommodate the connections inside the fitting.

Assuming you've got normal 3-plate domestic lighting, just run a 1/1.5mm 3-core+earth (6243Y), between your existing switch at the top of the stairs and your new switch at the bottom of the stairs. Get 2no 1-gang 2-way switches and connect as follows: top switch stick the red of the existing...

Is the connector enclosed inside the fitting? If so, then there's not a problem, if not then they probably intended you to fit it inside the fitting :!:

It sounds to me like you've come from the fused connection unit to the switch and then to the light, and you're intending at some stage you're intending to install a second light, again coming from the 2-gang switch? You're correct in what you say, your live feed from the supply goes into the...

Just so you are aware, if you use the connector blocks supplied with the lights without placing them in an enclosure, then the work will not comply with the wiring reg's. To ensure compliance, the joints should be within an enclosure (422-01-04), and this enclosure should be to an appropriate BS...

I will consult my 'CORGI man' before I do anything anyway because like electricians, everyone has preferences and different ways of doing things. If he says he would prefer to run the pipe himself, then I'll just have to do all I can to clear the route for the pipe as possible, but I'd have...

It's a little bit hard to make out, but see how this sounds...the feed comes in on the brown (and neutral on the blue), connects in with the brown flex for the lamp and another black. I would say that this black is the switch-line back up from the switch. This means that the switch is supplied...

I agree with breezer, ideally you'd be better to do the job properly and rewire it. But it may be possible to do depending on several factors. What size fuse is protecting the circuit? If the cable supplying the JB is 4mm, what size are the legs of cable coming off the JB to supply the sockets...

Sounds like there's been flex used somewhere for the fixed wiring of the lighting for some reason. If it's ordinary 3 plate wiring (feed in, switch drop, loop out), then those will be your 3 cables. If the lights work together from the same switch (or supposed to!), then you may have got the end...

The easiest way for you to find out is to grab a torch, switch off each MCB in turn, then turn off the main switch to the board. Swap your upstairs and downstairs lighting MCB's around. You must be absolutely sure that the board is dead before you do it, especially if you've not got an...

When you try to reset the MCB (stands for miniture circuit breaker) for the upstairs lighting, does it actually seem to 'blow' or will it just not reset back into the on position? Try resetting it slowly, you'll feel it if current is trying to pass through the breaker as it resets, it will pop...

Not quite, a PSCC test is a live test which measures the potential magnitude of fault current that would flow between live and neutral in the event of a short circuit (can also be used to measure the earth fault loop impedance or calculate the PFC ). Tests for continuity should be done using a...

Are you saying that every MCB in the board tripped at the same time? When you turn the upstairs lights back on, what is it that trips? Is there an RCD protecting the whole board?

That's a useful link thanks corgiman. I was actually going to get a competant person to install the boiler and test the pipework, I was just going to install the pipework and leave 'tails' (is that what you call them in plumbing?) near to the boiler position for the heating flow and return...

This post was started a few weeks ago now, but if it's still applicable, you are not required to take the supplementary equipotential bonding conductor within a bathroom back to the consumer unit (or main earth terminal if it's not within the consumer unit). Regulation 601-04-01 states 'Local...
