I still don't understand this farce, I've never seen anything quite like it. I've always held the UK standards in high regard until recently a couple of things have made me wonder. One was the knee-jerk earthing requirements for electric vehicle chargers which I understand they back peddled on for the mostpart and now this.... It's the fact they're attempting to electrically regulate an issue that is clearly not a electrical issue which means they're treating the symptoms and not the root cause which I suspect is a combination of falling materials quality standards and falling installer standards. Add to this the fact that there's a lack of clarity. I can understand the wholesalers ignorance, I wouldn't expect them to worry about anything other than their bottom line but even industry associations and groups can't agree on the implications and the precise standards of consumer units that should be installed.
