    MAJOR problem with supply...

    Just out of interest could western powers problems have caused this and would it be possible in any way for this to contribute to the fire. JUST STARTING TO GOOGLE.

    Ok Thanks very much. It's a shot in the dark, but are there any books that explain these sort of things.

    MAJOR problem with supply...

    The guys who installed the transformer are supposed to be coming out tomorrow with a SPECIAL tester , what ever that means. However I wanted to see if you guys knew a possible cause.

    MAJOR problem with supply...

    Ok Thanks. I have tested at every earth point in building and still got same readings. Even at earth mat for transformer. Another funny thing is that western power said they had an issue with one of their transformers the same time the fire started. However they will not look at this one as it...

    MAJOR problem with supply...

    Sorry title was a bit dramatic, but wanted to get as much knowledge as possible. I was working at a biomass factory today after they had a fire. Extension leads were apparently the cause. When doing a test at the db I noticed that L1 phase was at 272v to earth. L2 phase was 222v to earth and...

    EICR thoroughness.

    I understand that but are you saying the implications are risk of electric shock and arcing. Because won't the protective device just trip eventually. I have always carried out testing to the book as I always think knowing my luck I'll be the 1 in a million standing up in front of the judge...

    Enlighten me! As I'm obviously incompetent.

    EICR thoroughness.

    I agree with all. However why is low insulation resistance reading a code 2. What are the dangers associated with a low reading, or what can it cause apart from nuisance tripping? Thanks for replies. Oh and yes he takes ze from zs for r1+r2.

    EICR thoroughness.

    I have been doing An EICR report today with another electrician from my workplace. He has tested double the amount of circuits I have. Now I follow testing to the book however he basically said that he: 1 calculates R1+R2 and just measures zs as he says as long as it is ok what does it matter...

    British Gas.

    Hi just wondered if anybody knows how long it takes to get from talent pool to an actual job at British Gas. Also does anybody know if they are a good company to work for. At the moment I'm unsure which direction to go in. I have just been put in talent pool for British Gas and also I have just...

    Thanks for the reply.

    Glowing Led Chandelier.

    I have used 2 core strappers between switches which I thought would reduce the effect!. Could I fit the 2 resistors at the fitting between SW L and neutral?. I always worry about doing things that aren't the norm. Ie fitting resistors as I don't fully understand the science or theory behind it.

    Glowing Led Chandelier.

    Hi I know something similar has been posted before, but can't find it. I have fitted a varilight eclique dimmer with a chandelier that has gu10 dimmable megaman leds. When the switch is turned off the led's continue to glow. Am I right in thinking the problem is that induced voltage from the...

    Really strange RCD happenings

    I think you might be on the money with your post as it seems to be a neutral to earth fault. However would of thought it would not reset not be intermittent unless the n-e voltage is constantly changing. Also surely it would not affect the rcd not tripping when tested.

    Really strange RCD happenings

    Why doesn't the (bad)RCD trip when carrying out testing on it. That is at 30 or 150mA of test current also doesn't trip on ramp test.
