Metal conduit between two light fittings

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?

  • Is this a real issue, or just an office debate?

    What the lamp fittings are made of, even if they are double-insulated, is irrelevant. The risk arises from the cables passing through the conduit.

  • Hi Chris, It is a real issue, we are installing earths to the ends of the conduits hence why it started the discussion. they area GRP linear fittings the span is approx 1m of conduit at around 3m ceiling height
