Domestic situation. ENA and the COP for EV Charging Equipment require installers to notify the DNO prior to install if maximum demand exceeds 60A. We know that figure is easily surpassed using a 7Kw charger and the normal assessment methods. Reference to 722.311.201 allows load curtailment. Up until now, we have installed only one type of charger that can monitor load to the dwelling and throttle back power to the EV accordingly. Fine, no issues with ENA and we have been able to proceed with installs notifying the DNO after the event. . Now the same regulation allows load curtailment by manual means. So do you reckon if a client undertakes not to shower, cook etc while charging their EV, that can be recognised as load curtailment by manual means? If so, it makes a a mockery of the current arrangements!
I would have guessed that the intention was that manual load curtailment would be more like a manual changer-over switch between say the shower and EV - rather than relying on customer's promises.
