    Is there any advantage from the perspective of current ratings/de-ratings of using galvanised round conduit over same size PVC conduit? With both to be chased/buried in brick wall and plastered over? If so, where is this specified? Cheers

    Quick one. Is there anything in the regs that state safe zones for external placement of pvc conduit ? I've looked and can't see anything specific. Reason I ask is the installation I'm doing is needing me to run conduit at one brick above damp course.
