Hi Guys,
Recently asked to upgrade cu to mcb and rcd protection on old imperial wiring system in good condition. My problem is there is only a 2.5mm going to main water intake which is at the other side of the house and difficult to get to. If by improving the system with additional protection by rcd should I still require to upgrade main bonding ???
