    Petition: Make working with electricity a criminal offence unless qualified

    Sounds like that there are electricians here who feel threatened about others joining the industry. Almost reminds me of a closed society like the medical profession where people are handpicked because they know someone. People typically take apprenticeships because they either lack the ability...

    Petition: Make working with electricity a criminal offence unless qualified

    Here is a question for those who think that the petition should go through. I have a degree in electronics, I have always been hands on (having a workshop with MANY tools including bandsaws, drill presses, woodworking bits, table saws etc etc...), and I am a very capable person. I am taking one...

    Dodgy electrics in many homes >:(

    Dont have a picture but here is what it looks like (exactly as you described): http://www.mallinson-electrical.com/media/catalog/product/cache/1/image/512x512/9df78eab33525d08d6e5fb8d27136e95/2/2/2273205_1.jpg Chances are these push connectors dont give you the same mechanical contact strength...

    Dodgy electrics in many homes >:(

    Oh god is there worse to come? Mind you, I have seen the following as well: Piece of metal instead of fuse Scissors in earth to connect American plug Bare conductors with no insulation close to each other 80mA RCD in a TT system Downstairs light was not connected to down stairs light circuit...

    Dodgy electrics in many homes >:(

    General Technical FAQ's This recommends that the device be at least 300mm away from the sink which it is. But I cannot believe that this is good practice in any way. If you are in a situation where you have wet hands (or in splashing distance), there should be no out let or mains switch unless...

    Dodgy electrics in many homes >:(

    A member took a statement from my other post out of context completely. To be honest looking back on it I am not even sure why I posted the remark on BS7671 :S Maybe I'm just very tired right now (and ill with the cold, yay). What I was trying to say was that the switch is obviously close to...

    Dodgy electrics in many homes >:(

    I measured the switch and it is in-fact inside the zone 2 (around 40cm). When I said I do not need to read BS7671 what I was implying was that the distance between the switch and tub is obviously too close. By the way, BS7671 is not a legal document, its a guide line for common practice. In a...

    Dodgy electrics in many homes >:(

    I also forgot to mention how two, TWO, separate bathrooms in this house have a switch instead of a pull cord. Maybe they are outside the zones??? Nope, I can (no exaggeration), place my right hand over the faceplate and have my left hand in the running water. I dont need to read BS7671 to tell...

    Dodgy electrics in many homes >:(

    Hi Everyone, I have noticed that in the past three houses that I have lived in there are always dodgy electrics. In my bedroom there was a humming sound that always came from the ceiling rose but until now I assumed it was the dimmer switch. So today I changed the switch to a standard one (on...

    Trades Gateway - any feedback good or bad?

    I am doing the trade gateway course myself. So far I have been somewhat impressed considering that I am doing the course myself. Now I cant speak for all others taking this course but I believe that my situation is slightly different. For example, I already hold a BEng degree in Electronic...

    BS7671 Amendment Question (Regarding Shower Rooms & Tests)

    Hi all, long time no see! So I have this question that I need to answer for an assignment but there is an issue. I have a copy of the BS7671 Wiring Regs Amendment 3 (which has amendment 1 & 2 removed from the introduction). Question 1 asks : Which zone no longer applies to a shower room? The...

    Plastic fitting between two pipes and electrical safety connections

    Ah fantastic thanks!

    Plastic fitting between two pipes and electrical safety connections

    So if I understand it correctly... Earth bonding like that is only required if the exposed metal is something that can A) become in contact with a person and B) potentially become live via a fault in wiring near by. Many thanks!

    Plastic fitting between two pipes and electrical safety connections

    Hi again, So last night was very eventful! The fitting that sits between two pipes failed and leaked water all in the kitchen. Luckily my father was awake at the time and spotted this before any serious incident took place. We called a plumber the next morning to get the problem fixed (was...

    CPC Calculation

    So just to clarify.... If I wanted to test the earth wire resistance of a light on a radial circuit the method I described would work because it is a radial circuit. Many thanks!

    CPC Calculation

    Ok will do just that. But one other question... You mentioned Ring circuits which I agree with but what if this mesaurement was being taken on a radial circuit where it does not return to the consumer unit? Does the situation change then?

    CPC Calculation

    Hey all, To calculate the resistance of the CPC you end up with an equation with (R2 + RN) / 4 = R1 where R1 is the line conductors resistance, R2 is the CPC resistance and RN is the resistance of the neutral wire. My question, Is this method below also an acceptable way of doing it (if the...
