Hi,
1) done some work in an office, it was a simple job, to replace existing pendant lights to new ones. While the work was done, no changes were made to the circuit, no lights were added and of the values of the bulbs are the same. No earth was found for the lights wiring, (I know that this is a common thing), the wires coming out through holes in a solid concrete ceiling. The ceiling height is 2.5m.
My question is: Would it be OK (according to the regs.) to leave the system as is or I should add the missing earth (I wanted to do it but it looks a very complicaed issue, no access from the loft and the concrete ceiling, I will do it only if it is required by the regs.).
2) In this office there is a boiler room, it is about 2mx2m size, and it has in it the boiler and the CU (3 phase) and other rubbish. I had to add a double socket to an existing 13A F/S. I used T&E+cpc 2.5mm2, I clipped the T&E to the wall. Is there any reason why the cable should be in conduit or trunking? As far as I understand trunking and conduits are used for mechanical protection of the cable, conduit will be used with single core. The external sheath in a T&E basically is there for the same reason. Have I done it wrong?
Thanks
Albert
