Will 5-15 draw more amps on 20 amp circuit?

    Until I can get my HPWC I do have two 20 amp circuits in my garage. Can the 5-15 that comes with the car charge at 16 amps on that circuit or does the adapter somehow limit the charging to 12 amps?

    It limits the charging to 80% of the 15 amp rating. Tesla makes a 5-20 adapter that will allow 16 amp charging on a 20 amp circuit. It has one vertical and one horizontal pin to ensure you're plugging it into a real 20 amp receptacle...

    What are you waiting on for the HPWC - money or the electrician to come?

    If you are saving money / deciding, you can just install a different outlet and keep the the UMC.
