I have a Thomas & Betts panel with 40 slots and was going about trying map out the circuits when I noticed a few suspect breakers. The entire right side of the panel contains only T&B (type TB) breakers which I think are fine, but the left side has a mix (some T&B, but a few I suspect shouldn't be there).

I don't want to spend money for no reason but my instincts tell me at least some of these breakers should be replaced (for safety and/or code compliance?), which is why I'm posting here to see if I'm right and should fork out the ~$60 to replace them or maybe worrying for no reason and can keep my cash in my pocket.

Based on some other posts I've found here, I think I know what to replace them with. But, again, looking for feedback.

Here's what I'm thinking, and THANKS in advance! -Jwawa

P.S. I can post a picture of the entire breaker panel, but felt like I was pushing it already with too many pics.
