Hello all,
I'm in the process of cross bonding all the copper pipes in my bathroom to the lighting circuit. I'm using 4mm cable and keeping the run continous between all pipes and hope to terminate at the light switch.
What I'm not clear on is that how do I connect the 4mm cable to the cpc of the lighting circuit, as the ground terminal at the switch is already overcrowded with earths from ceiling rose & extraction fan (2 gang switch).
Is it acceptable to run a short piece of 1.5mm sleeved earth cable from the light switch to an earth block that accepts 4mm cable from the earthed pipes?
Also, the extraction fan is earthed the same switch, so I believe this too will be cross bonded with the pipes, without a need to run a separate cable to the fan itself. Any help would be appreciated.
regards
