It is a tnc-s system and the earth and bonding are upto standard it is an mem board about 12 years old with some circuits protected by an rcd but not the lighting
Does an outside light on an exterior wall of the property need to be protected by an rcd or can I supply the light by a 6amp mcb from the consumer unit using 1.5mm t&e cable to the outside light any help would be appreciated.
Does a new outside wall light need to be protected by an rcd and does it have to be switched .is it possible to run it on a 6amp breaker from the consumer unit to the outside fitting.would be grateful for any advice
