Quick answer: An EV charger needs a dedicated earth electrode with a measured resistance below 5 ohms — and it has to be measured with an earth tester, not assumed. This is the item most Pakistani installs skip or fake, and it quietly disables everything else: your RCBO can only clear a fault if there's...
