    Conduit for earth & PIR

    well yes it would.. that has a suitable sized cpc for the sub main and then radiates out to the smaller sub circuits with smaller cpc's.. the above scenario has a single sized cpc that can and does serve several points of several circuits along it's length..

    please help me

    take off the switches and tell us what wires / cables you have in each.. IF you have a white T+E at one then that's the switch wire at the ceiling rose.. ( which would be my guess since it would be odd for a sparky to switch cable sheath colours when doing the main wiring, but the switches...

    3 Phase DB Pics

    it's amazing the state of some of these old DB's in various basements and factories.. there should be mandatory updating every 20 years or so.. :mrgreen:

    3 Phase Coffee Machine

    please stop calling it a "wye" system.. the correct term is star.. they only use a Y shaped icon for it for ease of notation..

    Started My Diet...

    I will most likely need to have the overhang chopped off at a later date, but I'll give it a while and see how much it shrinks back on it's own.. skin is kind of like a balloon.. if you blow it up a little bit it will snap back to it's original shape when you let it down, but if you blow it...

    I'm out of work again from friday... :roll: had a meeting with someone working at my brothers place ( subbie ) and he may be able to sort me out, but it won't be for at least 2 weeks and then may not be full time ( maybe 3 weeks in every 5 he recons ).. I've sent out some CV's in the mean...

    Radial to Ring and other questions..

    it wasn't my place to rectify it.. the main sparky contractor was aware of it and it was done by one of their boys with written "approval" from the main site foreman to the effect that the damage would need to be rectified after the flat was no longer required as a show flat at an extra cost..

    Are.......

    you're better off shopping in B&Q warehouse for the little bits than CEF.. no one wants to hold stock levels that may or may not sell at the moment when they can get it on a day or so's notice..

    Rewiring a bungalow quote

    it's not always possible to run new cables down capping, so the sparky may have been warning that they might / will likely have to chase in new ones..

    Radial to Ring and other questions..

    it depends on what they are refering to.. a NEW socket that requires the installation of a NEW circuit in a shed is notifiable, an ADDITIONAL socket isnt.. ( as a NEW circuit is notifiable in all locations, ADDITIONS are not unless in kitchen / bathroom / special locations etc.. )

    Radial to Ring and other questions..

    The ground floor flat was the show flat.. all went well and was tested properly when they reported that plugging a small 110v transformer in was tripping the ring.. after some tracing it was found that they had sqewered part of the ring with a metal plasterboard fixing whilst mounting the...

    4 way dimmer burning out

    do the maths.. 8 x 40W (and you're certain that you've only put 40W lamps in them???) is 320W.. a lot of dimmers ( especially those for grids and multi gang ones ) will tend to be for 250W... yes you can get beefier ones, the next size up will be 400W, but that may be cutting it close...

    cd on ccu?

    school isn't domestic.. sockets usually under the control of the teachers and are more than likely installed to negate the need for rcd's because of hidden cables ( ie in steel conduit in partitions and / or trunking on the walls..)

    Radial to Ring and other questions..

    how do you know it's 2 radials? where in the west midlands are you? if you happen to live in a ground floor flat in a converted hospital in Tamworth then I may know what the problem is.. :) who told you that additional sockets in a shed are notifiable? IN the shed isn't IN the garden so...

    old wiring - light fitting

    take a photo and post it so we can see what's what.. I'd also tell the sparky to get back there asap and fix the dangerous situation he's left for free or you'll call the police and report him for attempted murder ( well what do you call leaving unterminated live wires hanging out of a wall or...
