    Bang!

    So I go to a job a couple of days ago in a small shop. One of the things to do is fix an RCD that isnt working in a dual RCD board (not that neat but ok, no labels), everything works but if you turn the RCD off it doesnt disconnect the supply to the 4 MCBs it covers. Also the test button doesnt...

    Earth goes bang!

    Hi all. Just went to a property where the water and taps were given a shock to the house occupiers. The boiler was cross bonded and had a bonding conductor run to the MET. But however surprisingly the property did not have the main earth. So I had connected a 16mm earth to the ccu and when I was...

    Ok, I must have done something wrong but cannot work out what, 3 phase BANG!!!

    Hi, bit of a rush job, but when double checked by me, then another spark could not work out what I did wrong. Needed a r1r2 reading on a feed from one of our DB boards to an isolator about 10m away. This circuit has been live for some time, just a double check was needed (d63 breaker was on...

    Resistors and capacitor going bang.

    Been doing some electronics experiments with the students. Fairly easy stuff, but i have to admit the last time i did this stuff was when i was where they are now, and that is more years ago then i will admit. Anyway, we have soldered some resistors in series and parallel, added capacitors and...

    "just bang it on an RCBO!"......... TABLE 41.3

    this slightly confuses me; whenever a Zs reading comes up too high, e.g on a particularly long run, to get around the problem if you cant change the MCB rating, I get told to change it for an RCBO. Table 41.3 of the regs gives max Zs values for both MCB and RCBO protection. If our Zs value...

    Pikeys and a stolen substation neutral cable = BANG!!!

    Hi, I heard about this on the news. Apparently all the local residents' appliances blew up due to a voltage spike. I couldn't figure out at first how this happened? Then I started wondering whether, because the secondary winding of the transformer is a 'star' winding and the centre...

    Bang! Large flash / bang at voltmeter tips.

    Hi all, Just had quite a fright & must say I'm pretty annoyed with myself. I've just tested the ends of a wire to check if it was live (using a fluke voltmeter) and had a massive flash and bang at the points of the probes). I'm annoyed because I should have isolated the circuit and...
