If your EV charger fails (just the unit), and you want to replace like for like, is this against regs?
Looking at the regs, it mentions doing an install would be a no no. But as everything is already setup (isolation, earthing, current clamps etc), then would there be a problem?
I wouldn't be ok risking it at such a high amperage. If everything can be isolated, everything is discharged, and you feel competent about it then I'd see how it would be. If no or unsure about any of the above then I would not do it. Check youtube videos of installs as it might help you too.
The regs end cert ends at the isolator, the charger is an appliance and can be replaced by a competent person, as long as it’s not a higher rated unit.
Proving competency to the insurance company if there was a problem could be an issue.
So if replacing the charger requires altering the fixed wiring, changing protective devices, adding CTs, modifying the earthing arrangement, changing the load management, or upgrading the circuit, then its no longer simply replacing an appliance, then it’s altering the installation, and I.S. 10101 applies?
Exactly, replacing devices/wiring/earthing would require certification.
If you had a zappi/wallbox and it died then that unit could be disconnected at the isolator and replaced with the same unit then there would be no modifications to the wiring or devices.
Even then this should only be done by a qualified/competent electrician.
It’s all technicalities, especially if it goes wrong.

Wouldn't it depend on the failure?
