Can anyone tl ell me how to work out the size of an existing supply cable.
It is a three phase supply into 200A fuses. The cable is buried in concrete ground and so I cannot see any markings on it.
I've had a look at the cables upstream of the fuses and they look to be at least twice as larg as 25 mm tails would be. But on second thoughts 25 mm tails would have double insulation and these cables only have single so could be larger.
Tha cable also looks triangular in shape.
The REC has split the supply from the 200A fuses into two different three phase 100A supply service heads.
I guess SWA cable often surprises me as the cores often look smaller then I would expect.
For example the cores on a16 mm SWA I was working with recently looked more like 6mm to me.
Any explanation would be very much appreciTed.
