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.
As I previously mentioned, it is the company who set the standard for distribution utilisation in their own area. Only the local DNO can understand the capability of their network, which incidentally exceeds far and beyond the limitations of a simple guide book, published mainly for small domestic/commercial installations
As regards, "In accordance with....." Western are being polite! they want the guide book to feel loved, to be wanted in the industry!
The wording in the post from Sparkingchip is years old, set by UKPN around 10 years ago. the wiring regs hadnt caught up then, but it started to use the wording a couple of years later, which is the pattern. The best example, probably was the creation of 16th ed wiring regulations, All of a sudden a whole raft of "special locations" appeared, The common or garden bathroom, farms, building sites, even a street bollard now needed special attention. Marinas, caravans, oh dear! Outside in the real world the former electricity boards had of course been guiding electricians since the 60s with their supply issues for all electrical installations. Before that, simple water pipe/rod earthing sufficed, but the area boards took the industry in to the great new world of PME networks, new cabling enabling Electricians throughout the land to achieve disconnection times unheard of previously. Voltage operated ELCBs, steel fuse boxes without an effective earth, all left behind thanks to the great supply industry engineers. Time moves on, and in recent years the London guys have been involved in projects bigger than before, Terminal 5, The Shard, new football stadiums and many new tower blocks. The EV strategy is in place for the area and the company will continue to increase its load capability accordingly.
