Various guidance shows running an additional cpc as a ring. What are the implications of running two cpc’s, but terminate them as the radial, each cpc being terminated in a separate terminal within a twin earth accessory. Each circuit cpc then terminated separately back at the DB. This would do away with usual steal link on the accessory. Amount of terminations would be the same.
Hi Andy, the ladder arrangement in 1 above could allow 2 or more points of failure and still allow all accessories to be earthed, due to parallel paths, this is not the case with arrangement 2
It seem the acceptable arrangements for socket outlet circuits provides a lesser degree of safety than those for fixed loads supplied by FCUs, Cant think where else in BS7671 this would be the case
