I am not familiar with the SANS wiring of premises regulations but have been told that socket circuits having the following configuration comply with SANS 10142, these are:

A ring circuit wired with 2.5mm2 cables, protected by a 30A RCBO and using SANS 164-4 socket outlets and,

A ring circuit wired with 2.5mm2 cables, protected by a 30A RCBO and using a mixture of SANS 164-1 and BS 1363 socket outlets.

Confirmation or otherwise that these circuit arrangements do or do not comply with SANS 10142 would be greatly appreciated.

David
