Hi folks. A friend has asked if I can install some lighting up in his loft space. He wants to be energy efficient, and I'm wondering which is the best way to go. It has cross-beams all over the place and no room to stand except at the centre, so he's generally only going to store stuff up...

Seeing the bleak description of the trade and the difficulty in joining it in another thread here, I mentioned something about it on Facebook. Someone has responded that two electricians he knows in Liverpool are having a very hard time getting any work, as there is a flood of Polish...

I've got my 2392 theory exam this evening. Am looking through a mock paper which has this question: What is the maximum earth fault loop impedance allowed when using a Type C circuit breaker giving a disconnection time of 5 seconds? The nominal voltage to earth is 55V. Is there a way to...

Hi folks. I'm just a student, so I will gladly profess my ignorance here :0) I've just seen a link to a Canadian TV news programme that referred to CFLs being the cause of radiation that has harmful effects on health. I looked for other links, but cannot find any science! All there seems to be...

I've just been to Specsavers for an eye test, who advised me that I should now be thinking about bifocals or varifocals. They explained to me that a lot of people don't like the line between the lens areas on bifocals, but on the other hand, the left-to-right field of sharp vision you get with...

I was curious to hear about HVDC transmission today. Being just a lowly student of the sparky art, I'd been under the impression that AC was the solution to efficient electricity transmission over distance. Now I hear that there's a 400kV tranmission line under the English Channel. (And other...

Just coming up to my 2330 level 2 exams, which I'm confident I'll pass, and with a following wind will get a distinction. Part-time level 3 from next September. I'm going to get on a Part P course this term ,which will be a one-day course for me, having done the 2330 level 2. So, I need the...

Here's a really stupid question. What symbol would you use for a socket outlet in a circuit diagram? In wiring diagrams a socket outlet is drawn fairly realistically; the conductors are shown connecting to the little rectangles representing the socket holes. Fine. In layout diagrams sockets...

I just did an informal test in my 2330 course for the 205 module exam. One question was this: At what depth should an SWA cable be buried: a)600mm from top of cable to ground level b)600mm from bottom of cable to ground level c)150mm from top of cable to ground level d)150mm from bottom of...

I'm in my second term of studying 2330, so I'm a little green. I went to have a look at a domestic service intake today, and where I was expecting to see a cut-out fuse, I saw this. Sorry about the poor quality photo, I couldn't get much light in there. Does anyone know what this cast iron hunk...

Hi folks. I'm in my second term of 2330 and am getting on pretty well I think. I've got this question which I haven't found a good opportunity to ask in our theory lessons, but maybe someone can clear this up for me. Up to now, the terms line, live and phase seem to have been used pretty...

Hi folks If I took the poll at the top of the forum, I'd have to put myself down as a non-sparky, but I will be starting training to become one in the autumn. So you might say I have potential ;) (See what I'm doing there? Heard it a million times?). Anyway hello! L IV

Hi folks I'd appreciate some advice on storage heaters. I need to buy four storage heaters for a flat and was about to buy Dimplex XLS range heaters, when I came across a range by a manufacturer called Elnur. All I know about Dimplex is they're very common. I know nothing about Elnur except...
