    Voltage Optimisers

    Hi I've been asked about intalling VO4 single and 3 phase optimisers but I have also been looking at the Marshall Tufflex voltis and just wondering if anyone has discovered any pros or cons with either. The voltis seems to be a bit better as it reduces it by a percentage rather than a set...

    Hi Guys, Just been to do a Condition report on a 30 year old installation. Both lighting circuits are wired in twin stranded steel cable with no CPC. The insulation test is good, but with the lack of CPC, and brass accessories, would you consider this as 'Satisfactory'. No RCD on lighting...

    quick rule of thumb, 3 phase current

    now this is not exact, but comes close. say you have a 3 phase, 400v motor, given the kW, to get an approx. value for the current per phase, (can be done in your head), just multiply the kW x 1.5. e.g. a 20kW motor. I = 30A. ( not allowing for efficiency, pf etc. ) just to give a rough idea.

    volex rcd

    hi just a quick one, as far as I'm aware, RCD's (with two poles, specifically the VOLEX VR80 30mA) don't care which side the Line or Neutral go in. Am I right? Or is this model a special case? Can't think why, I know it works on an inbalance betwixt L-N, and the bumpf says you can wire it...
