    Three Phase Board 230V

    Just after people's opinions seen this a few times and although not incorrect still makes me think: Three phase board 8-12 ways usually linked out to run on a single 230V supply. Seen second hand boards converted using bus bar to make in affect a 36 way single phase board. Always have been...

    LED fire rated downlighters - 12v or 230v?

    I apologise if this is a stupid question! What are the benefits of using 12v LED fire rated downlighters, over 230v LED fire rated downlighters? I assumed that this is more cost effective using 12v as although they are more expensive they last longer and use less power, correct? Can anyone...

    Small 230v stick welder.

    one of the fitters has fetched me a welder where he has welded threw or melted the earth cable, and main stick weld cable it is currently 10mm2 cable, my question is can i use 16mm2 tri-rated or does have it to be "proper" welding cable (as it seems rather expensive for a drum of it) cheers

    230v magnet

    Evening everyone, I maintain machines for a couple of printing firms. On one of the binders (built 1968) it has an electromagnet which when operated lifts off the brake on the main drive. The current mechanism is so worn its causing it to stick and vibrate like crazy. Any ideas where I can get a...

    230v 3 Phase Covertor Wiring

    Has anyone fitted one of these before? I have a Motorun 8hp Static Convertor that I have been asked to wire in. The cabling is all there it's just the connection I was a little grey on after chatting with the guy. He said the for 400v option to use Black & Brown Phases only and the Grey to...

    230v

    From the transformer as I understand it, it steps down the voltage to 230v (ish for argument sake) and then is supplied to people's homes. How do They design the transformers. If one supplies say 5 houses is it generating enough 230v for 500A supply. I know I don't need to know this. I'm just...

    110v v 230v tools

    Hi Guys, Working in shops and offices. Company is insisting using 110v tools and where possible, battery equipment. I would have thought that 230v + 30mA RCd would be more than safe. Believe that the 17th edition relaxed the rules on 110v tools (55-0-55) Your thoughts gents please.

    CAT 5 and 230V AC

    Quick question I am of course aware of the separation criteria in the regs but in reality what is the longest you can run a CAT 5e cable in parallel to a 230V cable before there are problems. Just inherited a site where a single piece of flixible conduit has bee laid in a floor to supply...

    12v & 230v in same conduit for replacement lights

    Hi A client has asked me to install some LED replacement lights which have remote driver (driving all lights) to replace some existing 230v downlighters. The existing lights are in a concrete ceiling supplied by buried conduits, of course I can re-use the conduits to feed the new 12v LEDS...

    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 floodlights operated by 2 12V PIRs through a transformer/relay with control box

    Hello, I would be very greatful if someone could help me with this problem. 2 x 230V flood lights are switched by a system consisting of 2 x 12V PIR sensors via a relay type setup with a control box. The 12 and 230v wiring goes into the relay box. There is some sort of control box (12V I think)...

    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...
