Hi Everyone,
I?m currently working here in Saudi Arabia as an Elec. Engr. where the standards being used are a mixture of both British and American standards.
My problem is one of the contractor here in the project will be using a 4core CU/XLPE/ PVC/ SWA(steel wire armor) cable for the low voltage system. For the circuit protective conductor or grounding conductor, they are proposing to use the steel wire armor of the cable.
I?ve read some forums that using SWA as CPC is allowed in British standards. However there are also some restrictions as regard to using the steel wire as a substitute for the separate CPC or grounding conductor.
Is there any particular article in NEC codes or British codes were using SWA is not allowed as CPC? If so can somebody lend me a copy?
Appreciate your help on this matter.
