hello all, just done a job to change a store into a small kitchenette. its in a commercial train depot, singles in pvc conduit buried in wall, has been tested by a nic tester and signed off. circuit protection is a 32a mcb, only chosen for the fact that the circuit is on the first floor, is commercial and all safe zones issues have been addressed also nobody of a general public type person is allowed to use or carry out any modifications to the lay out of the building, but the installation has been pulled by the maintainance sparks because of the mcb, quoting the 17th, any ideas were we stand?!! any answers full appreciated cheers.

think maybe if cables not buried over 50mm deep in wall or in earthed conduit it has to be on 30ma rcd. may be wrong tho but sure someone more experienced can give you the answer

ALL socket outlets need rcd protection complying with regulation 415 see reg 411.3.3 there are exceptions in 411.3.3 a & b but realistically you wont forfill them.

a) = under the supervision of skilled or instructed people.

but you cant guarantee that (cleaners etc) and how do you define skilled !

basically all sockets need rcd protection complying with regulation 415

remeber the reg youll be hearing loads about it:eek:
