    Has my builder f***ed up the wiring to my bathroom extractor

    How long ago was this done, and have you got the control notice back. All the electrics done in the extension should have be tested and certified and the originals left with you. If the work was done under building notification then copies of those would have been sent to the LBC and...

    Adjusting tone on Entrotec ED9 entry phone handset

    Did you read what you posted Entrotec has found that this can be a real nuisance for some tenants especially in flats with laminated flooring etc. Our existing isolated design handset can now incorporate an individual call tone volume control that is adjustable by an engineer on...

    Has my builder f***ed up the wiring to my bathroom extractor

    Looks like he as wired it as that standard unit which explains why the timer and grill is not working ..............yes looks like he as . But there again I bet i'm not as good at building a wall as a builder, so why do builders think they make good sparks. Just an aside, was this a...

    Has my builder f***ed up the wiring to my bathroom extractor

    Well the literature shows that a fan with the humidistat and timer should have a line, neutral and switch line, which means it as 3 cables to it. The standard has only 2, so the standard may be the one you have, as that may have the humidistat but not the timer. You don't mention if the fan...

    courses to update from 16th to 17th edition

    I think like Ericmark, we must be the old school. I remember when I did my apprenticeship the guy who trained me never had a qualification to his name. He come up through being a mate to an electrician onto an approved one. This guy could make conduit sing, trunking dance and I've never seen...

    Wiring safety & acoustic insulation

    Yes your right to check. Though insulation can de-rate a cable upto as much as 55% it is normally thought that where small cable are used, as in lighting and power this should not affect them to much. ie Even 1.00mm^ cable is rated at 11amps and derate it down to half and you still have...

    CONNECTING UP OUTSIDE LIGHTS.

    750 watts of a FCU is not a problem as that is just over 3amps. Get rid of the extension leads fit a FCU off the ring, making sure that the socket you take it off is not already a spur but is part of the ring. Then as BaS say get rid of all that cable attached to the top of the fence and do...

    Running 16A outlets off a Radial

    16amp sockets are mainly used for industrial purposes, what are you planning to run off the plug? Because if your need for a 16amp plug is to run something over 13amps then when you plug something else into that 20amp radial your getting awfully close to the tripping range, which is no...

    Building Regs - Swapping a ceiling rose

    You could use one of these as they are classed as a maintenance free box and can be pushed up into a ceiling void. Connect the cables from the rose into them and then come out in some flex. http://www.tlc-direct.co.uk/Products/ASJ804.html

    testing electric blankets

    Most of these blankets are classII equipment now and therefore there is very few tests that can be done on them. The (Mega) test most likely was just to prove continuity of the element, the visual which is 90% of all test even in PAT and making sure the thermostat cuts out at various...

    Just goes to show

    Unfortunately you would think so but rarely works out that way. Councils, housing associations as such don't want the hassle of dealing with individual contractors for this scale. It will most likely go to someone like Mears or an off shoot of Connaught Management that will start up under a...

    Strange fault, some clarification needed..

    If you have the double pole switch isolated at your CU then can not see there is a problem with the installation. You could make doubly sure by removing the L/N from the supply side of the switch and the main earth, that will completely isolate your installation. If you get the same...

    Just goes to show

    Was following the problems with Connaught and was really shocked. I subbed quite a bit of work from them in the SE over the last few years and will suspect so did quite a few other small contracting companies. So those 10,000 jobs in jeopardy could be quite a few more as I suspect quite...

    TN-S or TN-C-S which would you have?

    Quite supprised they are giving you a choice as TN-C-S is now the modern way to do it as it saves cost. Both systems have pro,s and con's as like everything in life. You get a more reliable Ze with TN-C-S, as JohnD pointed out on a TN-S system you rely on the cable sheath for the earth...

    RCD Tripping

    What made him think it was the cooker? If the cooker and the shower is on the same RCD side then the neutrals are commoned up on the bar. So a neurtal fault on either would trip the RCD. Did he try the shower on the non protected side? He may when he moved the cooker onto the non RCD...
