Metal conduit between two light fittings

Mark D Gray

Hi all,

we are having a discussion in the office and wanted your thoughts on the subject. If you have a metal conduit fitted between two plastic light fittings, the circuit is wired in singles (including a separate CPC), is there a requirement to earth the metal conduit?

    if the cable inside the conduit is normal singles then I'd say definitely yes too - the earthed conduit is the necessary 2nd line of defence.

    Perhaps if it was T& E or something, it would be arguably less important and just a floating conductive part.
    Or if the conduit was designed and treated like a live bus bar and in a suitable enclosure. 

    I suspect neither applies, so get those pirahna nuts at the ready ;-) 

    Mike.
