Electric load calculations are performed to ensure the safety and reliability of your electrical service with the car charger. We are required by the township to submit a proposed total electrical load calculation with all permit applications. A proposed load calculation totals up the current on all existing circuit breakers, including 2-pole breakers, and adds the new charging circuit to achieve the total proposed load. If the total proposed load exceeds the maximum amperage capacity, we will recommend alternative solutions such as a service upgrade or a load shed module.
