OP
Shakey
Thanks shakey for the explanation, does this mean selv on rcd is a must also, for the cable's protection? only if using a pull switch then no cables will be in the wall (less than 50mm) so am still a little confused to why rcd is needed for bathroom selv lighting
(or maybe i'm just having an elderly moment lol)
hey old fella
apart from the requirements for cables buried less than 5 cm, there is a requirement that all circuits in the bathrom are on an RCD
