I have a Model X arriving in late Dec (in theory) and should shorlty receive my wall charger. I had a sparky around today to give me a quote for an install. He is planning to mount an installation switch next to the HPWC. I would really prefer not to have that - this install will be in a car port next to our side entrance and so quite visible. I have found many pictures online of installations that do not appear to have separate switches (most of these are in the US I guess). Does anyone know whether it is a requirement here to have an isolation switch in Aus? I am going to have a dedicated breaker after all - so could always shut power down that way if needed. Appreciate any help on this. BTW I have three phase power in case that makes difference.
