Wall Connector

Our new Model 3 is to be delivered on May 11. I am installing the charger on May 10. Is there any benefits in using a higher breaker then 60 amp... I am able to purchase a 70 or 100 amp in my local big box store... I currently have a 60 amp breaker... should I return it for a 70 amp or 100amp? Thanks for your replies!

Depends on what m3 if u have LR , P AWD u can max at 48a with a 60a breaker.. if u plan to load share with two HPWCs than u want a 90a or 100a breaker

Anything over 60amps will do nothing for your charging speed. Long range Model 3 maxes out at 48 amps which will charge the battery around 44-45 miles per hour. Is the wiring already run? Make sure the wire gauge you’re using is correctly rated for the breaker you’re installing.

Thank you... I purchased from a local electrical supply shop... they said two go together!

Remember that the wire size determines the max current rate, not the breaker. The breaker should be sized based on wire size and length.

The wire should be sized for the current that will be drawn same with the breaker.

If you’re installing a single wall charger, then it’ll just be a 60amp breaker and appropriate wire. This will allow you to charge up to 48amps. If you set the wall charger to something lower, you’ll need to adjust the breaker to match.
