Wiring Ring mains to MCBs in consumer units
In my flat I've discovered that each end of the two socket ring mains
go back to separate MCBs. I've tested this by using a multimeter, turning off an MCB and still getting 240V on the live terminal (i.e I've got to switch off 2 MCBs to turn off the circuit). To clarify I have 2 32A MCBs per ring main, (4 in total). I would have thought that both ends of the ring main should go back to the same MCB (i.e. two wires into the MCB) The way it's been wired, each individual live wire goes back to an individual MCB. Have I got 2 MCBs too many in my fusebox. I think its wired incorrectly am I right Thanks. Jamie |
