No, we asked that question and advised that some of the main breakers were not "listed" for use in this equip. they declined and repeated they want 'only' the SP pushmatic C/B's replaced, and then "only" if we thought it was necessary.
Electure: That's the electrician being too lazy to bring in the ladder off of his truck!!

LJ: I have a question about the breaker in pic. 3 with the blue toggle handle (I'm assuming it's a GE). From the other pics, it looks like it doesn't line up as well with the deadfront opening as the others do. Is there any concern about being able to operate the breaker properly, or accidentally coming into contact with live parts inside?
I'm also wondering about purpose of the contactors. Are sections of these panels switched on/off from a remote location somewhere (i.e. ceiling lights in a large store, etc.)?

Mike - When the covers are on that C/B, as well as all of the others, operate properly. As you can see they have a mix-n-match set up going here. Many EC's over many years I'm guessing. There is no danger of contacting live parts with the covers on. The system is on an EMS (Energy Management System) that is what operates the contactors which operate the lights.

Right on!
I Can't say I have ever seen a "bulldog" panel that big and what looks to be in that good of shape... I still see some of those breakers around in the older schools used right in the classroom as both the light switch and O/C device... Hard to find replacements!!
