I mentioned in another post that I would contact HSE regarding any issues reported to them arising from loss of neutral and EV charging points. They have responded and confirmed that there has been no incident reported to them. However, they were made aware of a small number of situations that were a result of poor or no load management. I should point out that this is HSE in Northern Ireland.
Yes Mike, I am suggesting that a fine is necessary in order to prevent it happening often, figure from the HSE guy I was speaking too the other day was more than 1000 incidents last year. This is simply down to network maintenance being inadequate, a lot being from 1930s (where I live) and a lot more being older.
Would anything be gained by requiring the replacement of old infrastructure, unless there was also a requirement to return to "proper earthing" rather than PME.
Replacing an old DNO main with a new one will require at least two new joints per customer, one joint between the new main and a new section of service cable, and a second joint between the existing service cable and the new piece (it is most unlikely that the EXISTING service will have enough slack to be jointed to the new main)
Each new joint carries some risk of faults, including an open CNE. A new joint may be a greater risk than one that has survived for decades, at least until the initial failures in the new joints are discovered and dealt with. Though remember that each new joint that blows up probably requires at least TWO new joints for repairs.
I believe that all new DNO mains should be 4 core plus a separate earth.
