    RCD and shower

    sigh... and Part p has added greater weight to the whole debacle. Sadly Part P seems mostly concerned with preventing fires. Again most common source is non electric e.g chip pans and cigs. However it points its fingers at bodged electrics. Stuart.

    Dimmer switch wiring *peace of mind question*

    i don't think you have at all. The point i was making is that you were busy telling us how it wasn't semantics, but then your argument is 100% semantic. At what point did i say the neutral is not at zero volts with respect to earth/ground ?? Are you being deliberately obtuse? we are...

    Dimmer switch wiring *peace of mind question*

    The current alternates because it was induced by moving a magnetic field close to a coil of wire. A magnet has two poles N & S. if you alternate the poles of a magnet close to a coil of wire, a current will appear at the terminals of the coil that has a relationship with the position of the...

    Dimmer switch wiring *peace of mind question*

    <sharp intake of breath>cost yah :D</sharp intake of breath> Nope. better let them think about it. i have had a good rummage in the past threads on here. and often a good piece of advice is shot down by a caustic remark or comment. This forum is about helping people, not scoring brownie...

    Dimmer switch wiring *peace of mind question*

    I quite like this thread, some good stuff in here. But lets not mess about with the laws of physics ok? Phase line alternates between + and - with respect to neutral and earth. why? (i'm not asking, i want you to think about it) Does the neutral line terminate at the star on the...

    Ahem. in brit parlance it is called the neutral wire. earth is earth, neutral is neutral no matter what your earthing system TT IT PME whatever. Stuart.

    Telephone (Engaged)

    tandy used to sell them. As far as that circuit of bills goes, its a bit ott. one thyristor an led and a resistor will do. which is whats inside of the tandy ones. of course tandy is rip, but there was a company doing mail order in the uk for tandy products (radio shack in the US). Lat...

    dimmer switch drama

    probably ~ the two reds cable, one of the reds will be live all the time, and the other will go back to the bulb. The red, yellow and blue cable will go directly to the other switch. go have a look to make sure. You need to see what colour is going into what terminal on the back of the other...

    Which Consumer unit?

    ah yes, way off :D I agree, i wrote it all ass backwards. What i meant to write was. Light bulbs are known to cause tripping when they meet their maker, but we usualy put them on the non rcd protected side to prevent plunging the house into darkness when the rcd trips. i have just...

    Which Consumer unit?

    I see what your asking, and i'm not going to repeat the good advice given above. You are nearly right. Split load C/U means part of it is protected by RCD. The idea is to prevent nucience tripping of the RCD. Light bulbs are good at doing this when they meet their maker. I would not...

    Things to know before attemping DIY electrical work

    The onsite guide is none of the above. its just a logical reference. i.e they group all the regs for say EEBADS together. And volt drop does not matter? hmm what about common sense? The next occupier may plug something larger than a "hoover" in your socket. I recently visited a house...

    Things to know before attemping DIY electrical work

    Hi, 1. its not a straight forward answer. Your question does not take into account many factors that are considered during an installation. Cable sizing is a fairly complex job. you have to consider the design current and the potential fault current. You then factor in external parameters...

    IEE regs too complex?

    Well, its a sticky wicket this one. Q. Are the wooden boxes safe (as is)? A. Probably - hard to tell without an inspection. Q. Are the boxes a fire risk? A. wood is combustable, so yes. But if wooden boxes were in place, i would be more inclined to check the state of the wiring. I...
