Panel/Breaker Compatibility

The dead front cover was very difficult to replace on this service panel, which makes me think that someone’s installed circuit breakers that aren’t fully compatible with the panel. I would appreciate a second set of eyes on this.

There’s also the possibility that the cover was a replacement cover for the original, and may not be a matching brand.

I think I see four different manufacturers. From what I understand, panel manufacturers will have a list of compatible breakers. I call out mismatched breaker manufacturers for further evaluation. I do not attempt to cross reference them. Incompatible breakers are a fire hazard.

As said possibly tandems are not allowed. And definitely the Square D breakers are not allowed.

Refer it to a qualified electrician for correction.
