A cu change job entails running the main protective bonding lead 10M
vertically down an outside wall next to a lightening conductor(no it wont
be tiewrapped to the conductor!)In the past,black 20mm conduit has been used,but just wondered if anyone has found a smaller size,say
16mm or 12mm black rigid tube which would be more discrete for such
a job?.Also I,m assuming the lightening conductor would have to be
connected to the mpb somewhere.
Thanx for any help,

Open ended, PVC small bore piping, as used by plumbers could be a solution, or "clip on" type PVC covers as used for "hiding" pipes.

would it be permitted to use the lightening conductor ? a crimp at the top out of sight and a crimp at a convenient height lower down. so connecting it to the MET at the same time.


second thoughts maybe not such a good idea if its going to the gas main.
