Newbie with a charging question here. Into weeks I am having a professional electrician install my tesla wall charger. In the meantime I’ve been using the excruciatingly slow 115 V outlet to charge my car.
Today I received the 220 adapter as pictured, so that I could be able to Charge my tesla through my dryer plug.
In the breaker box my dryer is rated at 30amps, can I be able to use this low amperage or is the configuration not compatible with charging a tesla?
You can use that, but you need to dial down the charge current in the center display charge screen to 24A = 80% of the breaker rating. Beware that this is not really code compliant and contrary to Tesla's guidelines. If your house burns down the insurance may reject payment. It would be better to buy a 14-30 charge adapter from Tesla which sets the current automatically to the correct value. Having said that, I know several owners that use the setup that you are asking about.
