I have searched through the archived threads looking for a definitive answer to a question thats really bugging me. To be honest though i'm now more confused than ever!!!
Imagine the scene
25mm2 Meter Tails
16mm2 Main Earth Conductor
10mm2 Main Equipotential Earthing conductors (connected to the gas and water mains)
4mm2 Supplementary bonding between all pipes on the combi boiler(including the shower supply pipe) which resides in a airing cabinet in the bathroom
Here comes the question, does the shower have to be seperately bonded back to the incoming water main/CU or does the supplementary bonding suffice to keep it all at the same potential?
If it does need to be seperately bonded do i use 10mm2?
I really have managed to confuse myself into a frenzy about this.
I was really confident that the supplementary bonding i've already done would suffice but after reading through the archives i'm now totally confused and wonder if the shower needs to be bonded back to CU.
Please help
