whilst SWA may stop you putting a spade through it in the garden, it has no mechanical protection to a nail/drill, just like pyro/flexishield/split con. but the idea being that anything penetrating has to touch something at or close to earth voltage before the live.Spilt con should be treated the same as t&e regardless of whether its in the regs or not.It does not have any form of mechanical protection like SWA does.
