This was sent to the permit clerk by an owner that intends to install an EV charger. It came with the bid from the electrician.
Owner: If I decide to have them install a full sized circuit breaker, does that impact the permit at all? Here's part of their quote:
Contractor:
Note: It is always preferable to install a full sized circuit breaker for your EV charger. However, because your electrical panel is already very full of circuit breakers we will need to install a thin sized circuit breaker. This is acceptable per both U.L. Listing and National Electric Code but may put more stress on the thinner circuit breaker. This may or may not cause this thin circuit breaker to fail at some future time.
You have the option to install a full sized circuit breaker, but this would require us to install a new sub panel, which would cost approximately $1,200. This is not necessary at this time if we install the thin circuit breaker, but if this is an option you would like to consider, please contact us to discuss
