Our main 2000a dis board is 150meters away from the main incoming water supply .. We presently have a 50mm bonding cable going to a 25mm water incoming supply is this acceptable?..
Also our gas is 15meters away from main dis board . presently has a 50mm bonding going the gas 5" incomer is this acceptable ? in 2016 it had a code C2 put on it during a eicr im about to do a new eicr and just wanted to check as struggling to find much in the regs book about gas about 28mm
