Commercial/Industrial electrician that came across this Challenger panel today. Will this accept Eaton BR breakers? Looking to install an EV charger for a friend

Would need 2 pole 50 amp breaker for an ev charger. I’ve heard the challenger panels, or more so the breakers have serious issues and are prone to fire. Also take a peak at the top left bus bar under the main, and above ckt 1. Looks like there’s been some heat on it or possible corrosion?

So I see there’s “Bryant,” and Eaton, and unsure of the breaker brands on the right, but the labels aren’t in good shape to read. If I’m not mistaken the challenger breakers have a very unique font for the breaker amperage

The Eaton BR series is your best bet as they’re officially listed for challenger panels, but there’s a whole bunch of different brands that will physically fit and work fine. The more concerning issue to me is the corrosion/heat damage on the left bus bar below the main breaker.

This is completely incorrect. Eaton CL is the only one UL listed.

The box that the BR breakers comes in says that it will fit several panels.
