    Surface Meter tails, in plastic conduit?

    I'm quoting for a CU change, where I'll be replacing the meter tails (because of length). I will have to run the tails on the surface (less than 3m) on the outside wall. For a neater appearance and because the wall is pebble dashed, I was considering putting the tails (2 x 25mm) in 32mm conduit...

    EICR problems.

    Under what circumstances would a Sub-DB need to have MPB links to water and gas? I had always believed that the CPC of the feed from the Main-DB would be sufficient, assuming it had been designed and installed properly. Got a situation where you have a small Sub-DB in a caretakers office...

    RS switch mode power supply

    Hi Guys, Has anyone come across this SMPS from RS, 445-107. Blurb says its class 1, because it has an earth pin. I cannot get a circuit from the earth pin to the '-' of the output. I have sent RS a question about this but have not had a reply. Must fail it as a class 1 appliance.

    A friend of mine has offered me theses for £250. Very good condition but he now works for a company who provides them with testing equipment. Are they worth the price? And has anyone used these? I know the auto rcd is a draw back but I don't do huge installations so not much a problem. Thanks

    Pyro Cable Tripping RCD

    Went to a job in a church hall today where one of the power circuits was tripping the rcd. There seems to be 4 bad legs of pyro in the circuit, as I get a dead short in my IR tests between line/neutral, line/earth. Is it common for pyro cable to do this after a certain time, or could a fault...

    Taking a Part Passesor to a job you know has been done incorrectly?

    No not a job I have done silly :) Who's thought about it though? You've been to price on a job and you know full well that the quote is going to be ignored and some local mate will sort the simple 5 minute job for a couple of beers rather than the 500 odd quid that the rip off sparky wants...
