Yes the Swa been in some time, 2 core only,armourping used for cpc.Is this an older SWA install with the armour as the sole cpc ? If so I'd suspect corroded armour at one or more termination points.
Zs test only @ present..& that was documentedI did ask what test had been done earlier but the OP has not as yet answered.
Thank you…it’s now become a major problem & who is going to pay.As said needs a good looking at, and rcbo would temporary protect until powers that be sort out a plan. But doesn't sound good. Like for like, many would swap and walk away without testing.
that is most likely the problem. as someone has already stated, corroded armour. also depends on if the SWA has been correctly glanded in the first place, not just bodged. definitley needs investigation.Yes the Swa been in some time, 2 core only,armourping used for cpc.
