Breaker was damaged

Hi Gilberto,

I'm sorry to hear that. Can you please reply to your order confirmation with a picture of the damage? The support team can help troubleshoot or replace your breaker.

The breaker came right on time. Trying to find a 20/30amp tandem breaker was difficult till I found this site. I'll definitely be using this site in the future.
