To clarify, as an lockable isolator in the guidelines is not mandatory only "should include" and an RCD meets the requirements of an isolator, so no additional isolator required, therefore neither the RCD or additional isolator (if installed) doesn't have to be accessible?
If there was an emergency situation that the power had to be isolated, you could operate the emerg stop button if one is fitted to the charger, not sure if you can remove the charging lead while the vehicle is charging.
First there's the EV charging equipment; then there's the supply to it.
The isolator requirement applies to the final subcircuit, so may be remote from the EVSE
I can see nothing about how accessible the isolating device has to be.
It has to be "lockable" .
(Which is a requirement for all isolating switches under Wiring Rules; so shouldn't need to be said. It rules out fuses; but that could have been done more simply by saying 'isolating switch' instead of 'isolator').
And it has to operate in the N - which is the real point; and will be satisfied by any compliant RCD (due to ESR 24).
