OLEV Installation Auditor problems

whjohnson

It would appear that third party less than qualified and experienced individuals are being engaged as clipboard warriors to audit new EV charger installs.

Is there a publically available list of OLEV appointed EV charger installation auditors somewhere online?

Something smells very strongly of fish, and it isn't the charger units.

Cannot comment upon individual cases, but for a flavour -

Comments welcome.

  • BT sockets already have an arrestor inbuilt.

    Only between the A & B lines - not (usually) to Earth. So fine for protecting ordinary (earth-free) telephone handsets, but not a lot of good for anything with an Earth reference (PE or N) - e.g. mains powered modems, answering machines, ADSL....

    So, how effective are the devices fitted within domestic consumer units? How well calibrated is that blob of solder? Will it melt in time? How many MOVs will be monitored by the end user for deterioration over time? How many people will actually bother to replace them when the installation otherwise functions perfectly well?

    Yep in domestic installations the monitoring of the devices will not happen. It will be different, we hope, in say large office blocks, hotels and hospitals with planned preventative maintenance in place. Or will it?

    I thought that one line was at earth potential with a phone pair.

    I have personally seen the result of a direct lightning strike on a 70s brick and tile house. Some bricks were actually cracked right through on the outside. Also some decorative fairy lights that were around an upstairs bedhead vaporised and caused black marks on the wall paper. I do not believe that such an incident could have been mitigated by any small device in a plastic box within the electrical installation. Only a comprehensive lightning protection system could have lessened the damaging effects here.

    'Phones are cheap to replace. It is more expensive installing prevention than replacing a cheap phone.

    But SPDs aren't supposed to protect electrical equipment from a direct strike - they're supposed to protect them from damage or degradation from a strike at the other end your street or whatever. Type 1 SPDs are useful in a direct strike - but only to temporarily equipotentially bond the live conductors to the metalwork of the house, reducing the risk of a flash starting a fire. (They still won't protect your electronics in that scenario.)
