I am making a small 30 amp ring in a workshop. I'm just doing 2 double sockets, and an external via a RCD to start, and a couple of lights on a second ring.
I've a consumer unit with a 30 amp breaker and 10 amp breaker.
Now where I'm confused is ... if it's a ring presumably the consumer unit should have the outgoing live as well as the return live going into the 30 amp circuit breaker. But all the diagrams only show one wire. Is my presumption correct? Or should the return connect elsewhere in the consumer unit.
Leaving out for a moment the illegality of doing this work yourself....
power circuits are usually in a ring with both lives in same breaker & both Neutrals in same term on N bar, lights are never wired as a ring, always as a radial looping either at light or at switches, see 'Project' section of the forum
