A quick question following on from BAS's comments in Glyn 1959's thread to further my educashion ... Why does a pinched wire knock out an MCB? ** What's happening to produce the over current ..... or have I leapt to conclusions about cause? Thanks ** (Had this on putting in a new light...

My brother-in-law's brother is a Greek electrician (Sparkatus?). Having once lent him a helping hand on a job (in Greece), my Dad learnt a couple of interesting facts: 1) "most" Greek households are apparently fed by a three-phase supply. Whether or not "most" is accurate, it's clearly very...

I've been a viewer of this forum long enough that the mantra "you cant spur off a spur" is deeply etched in my brain. And I wouldnt ... oooh no, not me sir. However, there's a dull spot upstairs today which is preventing me recalling why you should not do the following: From a spurred socket...

I've removed a number of old, cut-off and hence unused cables from beneath the floorboards of our house (I just cant understand how people can leave them there - were they not potty trained?) Anyway, I was tidying up the cables beneath our consumer unit and, below the boards, found at least...

When we first moved into our house two years ago, the first thing I did was tape-up the cover on our main fuse as one third of it was dangling off it!!! Despite the fact I also noticed there was no main bonding, I am ashamed to admit that I'm only now getting around to sorting it all out...

I see frequent references to the need for junction boxes to be easily accessible. As most (older) houses seem to have a mix of looped-in-at-the-rose and junction box-fed lighting configurations (the latter entailing a number of them located beneath the floorboards and carpet in turn), does this...

My house has a flat roof extension which is lit by a line of 6 x 12v MR16 lamps. Their energy consumption is offensive (they're inherited) and I want to replace them with 4w LEDs. I have no idea how many replacement transformers I'll need - one hopefully - but with no access, I'm planning to use...

As an occasional user of this forum, I'm aware that "Part P" has been covered at some length (!) and that there's no doubt a definitive answer to my question somewhere in the hundreds of thousands of posts, but as I cannot find 'the smoking gun', forgive me for asking: is an average DIYer ever...

I'm filing this under "things I always wanted to ask ... but". I see that some multi-arm chandeliers have built-in transformers that use 10w G4s @ 12v. Given that low wattage GU10s run off 240v, what is that prevents G4s doing likewise? Is it that the reciprocal resistance of the filament...

Humble apologies if this has been covered before ... I'd like to install a PIR outside to turn on my kitchen lights - instead of an outside lamp - using an override switch (i.e so I can use kitchen lights normally or have them controlled by the PIR when we're out). My initial thoughts are...

Thoroughly enjoyed last week's epic BAS / Paul_C dong dong on the "outdoor lighting" regs. (Got through some serious amounts of popcorn). Anyway, I have an additional question on outdoor cabling....... Just moved into a house that appears to have a radial circuit downstairs (well, it has...

Could someone please explain the wiring for a PIR to give it an override function? (I'm assuming the lamp is separate and I know most modern units have this function in-built - but this is simply a hypothetical question. I'm a novice but recently replaced a 'modern' PIR lamp and reading around...
