I'm about to board existing wiring runs and want to make sure everything is in place before it's all done. Electrics are from above so will all be covered over and wont be able to change them.
The original earth bonding was taken from the shower fuse switch in the ceiling and then dropped down to the radiator tails and toilet. No earthing on the basin or bath as these are in plastic pipe. The radiator is also in plastic so can't understand why they bonded this and not the others.
Question is. is it safe to bond from the earth of the shower cable and also do items need bonding if plastic pipes are used anywhere on there run. Seems to defeat the object? If the tails up from the floor are copper do these need to be bonded if the rest is plastic?
Just to add the shower is connected direct to the main board in 6mm with a 32 amp rcd.
Regards
