Is that WPD for you Sidey?gordy,There is no requirement for isolation every 3m, the 3m thing comes from most DNO's only allowing 3m max of tails to be protected by their fuse.
Any more than this (DNO requirements notwithstanding) requires a fused isolator aka KMF to protect the tails, even if the fuse is identical to the DNO device directly upstream.
It should be on the DNO website or available from them FOC, under ESQCR requirements.
As I have said again numerous times we are lucky around here we have a good DNO.
We have them, they do try and help but can't always manage it unfortunately.
