    Look what the supply company buried in my garden! (The result of years of argument - don't give up!)

    I have for years been trying to get my existing split-phase supply upgraded to three phase. The DNO sent me a succession of ridiculous quotes, all around the £25K mark. No amount of negotiation, or pointing out that the existing transformer - which supplies only three houses - was ancient, had...

    Morning gents, Im trying to find a wiring diagram for a three pole (three phase) contactor, using a 24v coil. Ive found plenty with a 240/415v coil but none with a 24v coil. Im assuming theyre both very simular, only difference being you'd have to pick up your 24v from a different source instead...

    Calculation of KW use of 3 phase heater on single phase

    Hello I have been asked to install a sauna heater. It seems that all sauna heaters are 3 phase but the phases can be bridged to run on single phase. However, I seem to remember there is a calculation for figuring out the difference in power when running a 3 phase appliance on single phase. I...

    Ford Connect Double Locking Fault

    My Ford Connect double locking has stopped working (intermittent fault). Manual says it won't double lock if one of the doors is open. Well I've shut all the doors properly, but I guess one of the door switches is telling the system I haven't. I know the side door has got one of those three...
