[QUOTE="apprentice87, post: 392936, member: 13534"] Hi Jimmybobbob. No, as all extraneous conductive parts [say like the building frame, or steel gas or water pipes] will, or should have been, bonded to the MET, so all your cable armour is doing is acting as CPC for the new board, so just enter: Material; SWA. CSA; SWA, as Sidewinder says. Now, if your cable was feeding a SEPARATE installation, say like an outbuilding, THEN the armour could well be used as a bonding conductor linking any extraneous parts of the new installation back to the MET... Oh, and the answer for the CSA or the 4 core 25mm cable armour is 70mm with a copper equivalent if you need it of 22.5mm john.. [/QUOTE]
