I'm following, to do some maintenance at a works, where acontact electrician who is completing the re-wiring of the office area.
The following came to my attention and wonder if the regs change so fast that Icannot remember which was the latest edition or amendment or whether everyelectrician is trying to confuse the rest! If I don’t know something I say so.I would appreciate any comments on -
1. Main bonding of services include central heating. Therefore this may be thecentral hearing pipe at the heating boiler. And to make sure all pipes areconnected some cross bonding of all the pipes to the pipe where the mainbonding conductor was connected.
2. Metal plaster depth back boxes should have an earth fly lead to the circuit protectionconductor e.g. on 13 Amp socket.
3. Grommet should be installed in metal plaster depth boxes even if the sheathof a twin and earth is passing through.
The electrician told me none of the obove is any longer required, that was the old regs.
If all comments come back negative I will give up. How can some things berequired in one issue of BS7671 and then not in another! I can only assume theexperts are not experts!
