    image.jpeg image.jpeg I just wanted to share my findings with this picture. From 4+ days to a bit more than 4+ hours.

    I just had a NEMA 14-50 plug installed outside of my cottage.

    And apparently in Canada you can only get 32 Amps out of a 14-50 plug while in the US you an get 40 Amps. That damn exchange rate strikes again. :)

    Even my electrician was surprised but then realized that Tesla changed it. I do however get 72A on my HPWC at home.

    I'm curious if a US car will also drop down to 32A in Canada when on a 14-50. I may have to seek out a 14-50 outlet when in BC this summer...

    I'm told this is only a recent phenomenon. Previously it was 40A just like our friends to the South.

    No, it's caused by the newer 14-50 adapters sold in Canada. So long as you're using your US one, you'll get 40a.

    The Canadian ones would be handy for folks in the US who only have a 40a circuit, though.

    Got it... Didn't know if it was car-side or adapter-side...

    Unfortunately they'll cancel your order if you explicitly order the Canada one in the United States. I tried. Actually, I need to go make sure they refunded me for it...

    Very nice! One suggestion though, you may want to get a holder or shelf for your MC in order to eliminate the strain on the cable. Another possibility is a short extension cable with weather protection.
