    Hello I am new to this forum and need a little help from an experienced spark to help me design a circuit to wire a detached garage (two sockets and ceiling lights) from a house ring main to 18th edition standards. This will be notifiable so everything has to be pukka. Cable can be in steel...

    ring circuit for a submain?

    trying to find answers in the reg book, but is there anything to say you can't install say a larger ring circuit for a sub main? to reduce volt drop / cable size etc. Normally you would obviously install a large enough cable, but would this be acceptable , whats our thoughts?

    OK to spur lights from ring main?

    Hi, I want to add wall lights to a room, but don't have access to the floor above, so can't easily access the lighting circuit. There is a power socket on the wall where I want the wall lights. Is it permissible to take a fused spur from the ring main for the wall lights? Regards, Glenn
