Hopefully a quicky for you. I have a semi-converted garage which is used as an office. I replaced the CU in there as the old one was knackered. I have 2 MCBs one for the mains and one for the light. The mains sockets are all fine and working but I am a bit confused about the lights. I have 1 switch and 1 light. Can I feed both lives in to the live on the MCB and both neutrals and earths in to the busbar on the CU?
