Replacing Circuit Breakers

[SideShow Bob]

If it is a Square D panel, get breakers that are compatible to the panel. The top breaker appears to not be seated correctly, or is mismatched to the panel.

Home Depot will carry Square D compatible two pole breakers.
As far as the one breaker tripping 3X Dailey, you may have other problems than a weak breaker, you need to check current draw on the load side of the one that is tripping.

As far as the one breaker tripping 3X Dailey, you may have other problems than a weak breaker, you need to check current draw on the load side of the one that is tripping.

This is what I was thinking, and I know nothing about home electrical.
