    Replacing halogen GU5.3 with LEDs - tried twice and failed - help please.

    That is not a transformer, it is a switch mode power supply which LEDs do not like. A true transformer would probably work, but an LED driver is what you need.

    UK Converting single pendant to downlights

    Why? You only need 1.0mm for lights. Save money, save copper, and drill a smaller hole.

    Outdoor lighting install

    NOT IN SERIES. They must be wired in parallel.

    Shaver sockets and (unnecessary (?) isolation switches)

    Fused spurs are not used or required on lighting circuits. A 3a fuse will have no discrimination against a 6a MCB.

    Cooker Extractor Plug or not

    You don't need any of this, it is just the latest fad. Four items all at one place on the ring is not good practice either. Put the cooker hood socket near the hood or perhaps in an adjacent wall cupboard.

    Customer Demanding We Pay For Her Blinds ££££££ Need Serious Advice.

    Point out to her that all electrical heaters are 100% efficient as all the electrical energy is converted to heat.

    Question from a wetpants

    Part P is a building regulation. The 18th edition is a wiring regulation. Neither are qualifications. Anyone can change a shower. He/she has to do it safely and of course it should be tested and the results tabulated. There is no requirement for an isolating switch, pull type or otherwise, as...

    I need an advice about Economy 7

    Electrical heating is 100% efficient however you use it as all the electrical energy gets transferred to heat. But it is expensive, approx 3 times the cost of gas. If you have a dual rate meter it will be cheaper at night, but your standing charge will be higher.

    Hardwiring under cabinet lights

    I have said a 13a socket should not be on the lighting circuit. Typo corrected. ('not' added).

    Indeed I did.

    Hardwiring under cabinet lights

    I never said a 13a socket should not be used supply lighting. I have said a 13a socket should be on the lighting circuit. Not the same thing at all.

    Hardwiring under cabinet lights

    That says it can be wired to fixed wiring. That would normally be ring final or 20a radial. It does not mean lighting circuit.

    Hardwiring under cabinet lights

    Simply because a 13a socket on the lighting circuit is bad practice. If you must have a plug and socket use a 2a or 5a one.

    Hardwiring under cabinet lights

    But that sort of sloppiness is how these incorrect terms propagate.

    Hardwiring under cabinet lights

    Thousands of examples of bad practice does,'t make it right. Imagine someone, maybe a wife, going up there and deciding it needs a clean, lugging a high power vacuum cleaner up, and plunging the place into darkness with no floor boards there! Anyway aren't most aerial amplifiers phantom powered...

    Hardwiring under cabinet lights

    Putting a 13 amp socket on the lighting circuit is bad practice. Don't do it. Just remove the plug and wire it into a junction box. Incidentally LEDs don't have a transformer which is an AC device and LEDs need DC. It will be an LED driver or power supply.

    You can't spur more than one fcu from any socket...?

    Well that is allowed anyway.

    Irreverent to the UK.

    Rewiring - Some questions, don't want to get done again...

    Rather irrelevant though to the UK.

    You can't spur more than one fcu from any socket...?

    Wrong. You can have many spurs, even more than one from the same point, but each spur can only feed one socket outlet (single or double) or one FCU.
