3 core Swa feeding ip rated plastic sockets outdoors.
He 3rd core of the Swa has been used as a cpc but the armour is not connected to earth; but has been made off with metal banjos. Would this warrant a C2 or C3? I'm assuming as the armour isn't extraneous a C3? ?
Thoughts please ...

Hi guys,
Wondering if anyone knows the ccc of SWA armouring.
Will armouring of 2 core 16mm SWA be sufficient for earthing CU with 80a loading or is 3 core necessary?
Couldn't find anything in regs regarding ccc of armour.
Cheers,
Drew
