Question:
I have a bit of bonding cable that goes from my water pipe, (ok, the house's pipe) then to the gas pipe and thereafter to the MET. It leaves the waterpipe, with its nice safety label intact, then gets attached to the gas pipe with another proper safety label, the bare conductor being wrapped round the screw, not cut, and finally to the MET. That, in my view is one continuous conductor.
However, if it is snipped at the gas pipe label, say a terminal is added, then the next run also has a terminal added, and both terminated ends are properly secured to the warning label, then finally the second length goes to the MET, then is that not also a continuous conductor? In effect, it is, surely?
In practice, it differs because undoing the midpoint temporarily then leaves the system unbonded, but if the bonding cable is not cut and joined at the gas pipe, removing that gas pipe label will leave the rest of the system intact. Now, I'm just trying to get my head round this, ok? It seems like terminology is causing confusion...continuous may be meant to mean one unbroken run, or maybe it means don't go wandering off popping short lengths into connectors and joining them up any old where?
I'm thinking that if the MET is in the "middle" of a house, and the gas comes in 10m away on one side, and the water 10m away in the other direction, then we have two things:
1. Quite a big house
2. A situation where it might be preferable for 2 separate bonding cables, one from each incoming supply, to the MET, each about 10m long, rather than running a 20m cable from one to the other then another 10m to the MET, which I would think would be awkward and more prone to damage, especially the 20m run.
Just my ramblings, and not those of a qualified person, however I am old enough to be shouted at, if required.
