Curious about supplementary bonding, I have these two 4mm Cables loose and not connected to anything in my parents house. I presume they are for the hot and cold copper pipes, my questions is do i need to join/make a connection between the hot and cold pipes? I work as an electrical improver working towards my am2, but my training has always been based on rcds for additional protection, not supplementary bonding, i understand these 4mm will be connected to earth somewhere, what i want to know is, if i get two bonding clamps, one for each pipe and connected between they two, would this be okay?if someone with a better understanding could explain, that would be great. The house has dual boards, only the sockets have rcd protection currently, the boards need to be upgraded, I have attached some pictures.
thanks for any answers.
