If you have a TT supply 16th edition board that has a 100A 100mA types-s rcd main switch and you wanna work on a lighting circuit that is on the side of this main switch (not protected by the 30mA RCD) do you have to either:
* move the light MCB over to the 30mA RCD side or,
* change the MCB to a RCBO or
* nothing can you just leave as is
just looking for little clarification
cheers peeps
