Are push on style breaker load centers OK in commercial builings? And where,if at all,does it talk about it in the code book.

I don't believe the code mentions them. As long as they are listed for the use then there should not be an issue. What kind of breakers are these. The old Push-a-matics?

One of the most popular commercial and industrial breaker panels boards is the Square D I-Line family. This family is only available as a 'plug-on' style even thought it has breakers that go from 15A up to 1200A.
Neither the NEC nor UL define residential, commercial, or industrial for panelboard construction. Loadcenters is also not a defined term even though most of us think of 'cheap residential' when we hear it.

I think you are correct in that the OP is talking about push on vs bolt on breakers. Generally speaker commercial jobs use bolt in but that is usually a spec by the engineers rather than a code issue. I did a small retail store and used regular push on style breakers.

Yeah, it's just a engineer or customer spec unless a higher AIC rating is required. Square D makes a panel (NQOD) that takes either type. They also make a 277/480 volt panel that does the same, I think it is a NEHB designation? But have rarely seen plugins used in it.

Pull-off disconnect with fuses may be?
If it is what you are talking about yes, it is commonly use when AIC cordination is required ( 3rd device)

NEHB was discontinued at least 10-15 years ago. It was plug on/bolt on style IIRC. I know there were plug on breakers - the EH series I think. Today they have the NF series panelboard and it accepts bolt on breakers only.
