Hi Guys,
Was showing a contractor where we want some additional network data points installed yesterday, i work for a college btw. An office is being created out of one of the student training pods in the plumbing centre. All of the pods have a single power socket and a light fed from a small CU with an emergency stop button to cut the power.
As we passed the emergency stop button the contractor pressed it and chuckled to himself when the trip popped and then told me how it was wired up. The CU has a 80amp RCD main switch and has a 32amp mcb for the sockets and a 6amp mcb for the lights, the emergency stop switch is connected between the neutral and earth on the outgoing side of the RCD so when its pressed the RCD trips and cuts the power!
The contractor i was with did not install this setup but has carried out some maintenance (changing damaged sockets/lights) which is how he knows the way its wired. It should be wired through a contactor he said but its not against the regs the way its been wired.
Anyway just thought id share that with you guys and see what your reaction is
All the best
Dan
