What is this panel?

[jaggedben]

I've neverseen a service panel like this. My guy who visited this site neglected to get readable pictures of the label. He wrote down that it's a GE. Catalog TPM2420MF, but Google is zero help with that. I'm probably going to be sending him back but I thought in the meantime I'd ask here anyway. See attachments.

If you have any knowledge about this type of panel, these are my questions:
- Is this a split busbar panel?
- What would the bussing rating likely be? 2@ 100A each?
- What would those 100A BR main breakers originally have most likely been?
- What kind of quad or tandem breakers can I legimately use in here? What would you say about the BR breakers?

I'm thinking that may not be split bus but rather a center feed style that was factory built with a 4 space 200 main breaker. Maybe it failed and this someones idea of a fix with the 2, 2 pole 100s.

And as a LOL, oh we Americans. I noted the Sub Zero, wine cooler, car charger, etc labeling in the first pic. Funny how we have high end "stuff" that is visible but the infrastructure to run it is 40 year old junk. Don't get me wrong, I have no issue with the finer things in life, I just like my infrastructure to match.

I do see at least 5 different brands of breakers in there: CH, GE, Bryant ("disposal"?) and two others. CH is clearly the newest, what with all the tandems.

If the panel is a GE, I suspect that the original main breaker was a THQMV (which has a 22kAIC rating vs the 10kAIC rating of the CH2100s acting as mains)

Scrap metal.

Seriously.

If it were one with a main that utilized 4 spaces then it wouldn't have the main lugs that are on the right side. The main lugs would be part of the breaker and the breaker would close the circuit to the bus, instead we have load wires off each 100 amp main and mains are apparently supplied by the bus.

Only two section panel similar that I recall seeing is some old Pushmatic panels. A 200 amp Pushmatic panel usually had two 100 amp mains and two vertical bus sections each fed by a 100 amp main.
