EV mobile connector
EV mobile connector
I will be installing a Tesla wall connector after the lock down is lifted. At the moment the car is being charged by the Tesla 3 mobile connector. Does anyone know if the mobile connector is required to be protected by a Type B RCD or can it be protected by a Type A RCD (because it has contains appropriate equipment that ensures disconnection of supply in case of d.c. fault current above 6mA)

Re: EV mobile connector
This would be a mode 1 charger, the "Guidelines -1.3 General requirements" issued by worksafe state a "A-Type" RCD, Mode 1 charging outlets must only be installed in a domestic or similar installation.
Remember these are guidelines and a good set of instructions to follow but they are NOT cited standards or legislation.

Hi,
This is probably a bit late,
Sorry but that's a mode 2 IC-CPD. (unless my Google search for the model is wrong, I remember Tesla originally made a mode 1 charging cable with a portable RCD inline.)
Mode 1 is basically an extension lead that plugs into a socket outlet and then into a car - there is no monitoring or control carried out of the supply and communication with the vehicle. For a car, this is dodgy as it can easily overload the supply infrastructure (socket outlet, wires etc).
Mode 2 has these monitoring functions and the IC-CPD 'knows' what plug is on the inlet and therefore how much current it can pass to the vehicle.
To answer your question, it is not against the regulations for an EV to be supplied using an IC-CPD (mode 2) that is connected to an existing socket outlet. The WorkSafe guide outlines and confirms this.
Id recommend that you supply mode 2 through a type b RCD protected socket outlet if one is being installed. If the socket outlet already exists, then please use one with a type A RCD at a minimum.
An IC-CPD would not pass the testing required of a portable RCD, at the most basic, it doesn't have a test and reset button, let alone being voltage independent.
Remember the philosophy in New Zealand - replicated in AS/NZS 3000 is to protect the full circuit - not just the appliance (unless its already existing, hence why we all have a portable RCD in the van)

Hi there
Worksafe amendment (issued Oct 2019) to the Safety Guidelines under "Principles of safety for EV charging" state:
"Where an EVSE is installed at a residential installation, the charging final subcircuit shall be protected by a type B RCD and the subcircuit shall originate from a MEN switchboard".
Yes they are only guidelines but its good to have something to follow and back you if something goes pear shape.

Re: EV mobile connector
Yip your correct.
But an iccpd isnt installed, it is just pluged in by anyone so not affected by that clause.
