This is a defective breaker. I bought another one at the electric supply house and took it back. They honored it because they sent it to their supplier.

This product had a slot where one of the screws should go missing! Had to be modified and if I did not have some knowledge it would not have happened and we’d be without electricity another couple days. Was very disappointed this type of important product was not complete.
