    Odd problem with an 230v to 15v plug-in transformer...

    Nothing to do with the usual installed electrics, but thought I'd ask here anyway... I bought a car "jump starter" a while back and used it a few times (it's an air compressor as well). I went to charge it recently (it's supplied with a 15v AC adaptor) but as soon as it was plugged in, the...

    calculating 230V

    we make calculations based on a supply voltage of 230V, but in most installations the average is 245V. now a fixed load of 6 ohms would have the following current increases 230/6 = 38.3A 240/6 = 41.0A 250/6 = 41.6A my question is why do we use 230V when an average supply voltage is giving...

    230v on neutral and line to earth at light fitting?

    This is with the lamp & fitting removed and the reading is taken from the chocblock connector at the fitting. The neutral is looped at the switch and it's only 230v upstream from there when the switch is made. Apparently there's only one fitting on this leg and all other lights on the circuit...

    Garden lights 230V or 12V?

    Which do you prefer? I must admit I like to sit on the side of safety so would feel better knowing I had a 12 Volt light setup but what do others think? I mean the garden is probably the most dangerous place in a domestic set up for any electrical equipment. Thanks.

    Converting American 120v to British 230v

    Hi guys, Went to a american customers house today where she wanted all her american table lamps put on a 230v 3 pin plug top, rather than use her plug transformers. I told her that she would need to change the lamp holders and wiring to accommodate the new voltage, which wouldn't be easy. And...

    is it 230v or 240v?

    Why is mains domestic power referred to as either 230v or 240v? Why not settle on just one of them? (My limited knowledge tells me that the reality is usually 243v or 237v - is that right?) Cheers.

I am using the original wiring (just removing the transformers obviously!) and there will be the same number of lights in the same places. Does this require part P notification or does this...
