Thought it looked too small for that.flexible steel conduit
522.6.6(i)There is much debate over on the IET forum about wether BS 8436 cable is suitable for use in this situation.
Yes, I saw that, and read the Voltimum doc....http://www.theiet.org/Forums/forum/messageview.cfm?catid=205&threadid=22246&enterthread=y
While they claim is is metal conduit it looks to me more like american style armoured cable.Anyone know the name of the metal stuff shown in use, within the PE mag
are they simply trying to get us to use the oval pvc conduit?
Which means, of course, that even if you aren't using the armour as the cpc you can't bury 16mm² 3-core SWA, or 16 or 25mm² 2-core, unless you RCD protect it.PVC is no good, the part of the requrement referred to by Pensdown referrs tor an earthed conduit complying with BS EN 61386 and satisfying the requirements of the regulations (BS7671:2008) for a protective conductor.
