    Cancel that. It's been the length of mains side transformer tails that we've found as a pretty common issue on new installations.

    Sorry for the confusion.

    Installation of 220v downlights

    Is this legal? 12v downlight fitting with 220v globe, 220v porcelin globe holder with 150mm heat resistant leads connected to 16A connector strips. My supply is 220v, 1mm t&e connected to the connector block. Leads are +- 150mm away from light fitting. Also: Draw box in roof, leads going to lights and supply from D/B. Lead going down to 2 way switching, using 1mm t&e. If earth is insulated on both ends, can it be used as a life feed?

    I'm confused, if it has a 220v globe then it's a 220v downlight. Why do you say it's a 12v downlight fitting?

    This is illegal on more than one account. Do not use the earth wire of any cable as a live, switched live or a neutral. If somebody gets injured whilst working on or using this installation because the regulations have not been followed you might well find yourself in court on a culpable homicide charge.

    i see a lot of 12 volt fittings used with 230 volt lamps .it doesnt have the built in lamp holder. some electricians earth the 12 volt fitting and use the porcelain 230 volt lamp holder. the connection of the leads is in a box,but the leads are still exposed the same as the 12 volt lampholder.therefore i fail it anyway.
    you can buy this contraption that fits on to the 12 volt fitting with a built in lampholder and connection box.
    as andy says using the earth wire as a live conductor is highly dangerous and illegal.

    When I find an earth wire being used as a return my prices double for "danger-pay", (what else is wired like that?). I show the owner exactly what the problem is and scare all the crap out of them with a very detailed descripting of how their whole family could be wiped out trying to help the grandchild being electrocuted. By the time I am done with them they rather sit in the dark, until I can do the repairs, than touch a light switch.
