We will be re-habing this next month. Appears to be in fair condition. Anything specific we need to look for? (i.e. replacing push-o-matic breakers, re-tourquing etc.)

On a quick look, the grounded conductors and the Equipment grounding conductors are on the same bus...is this the service disconnect, or downstream of it?

This could be service equipment if you can deenergize the entire service with six throws of a 2 x 12.

Immediatly to the left of what you can see in the main disconnect, 800A I beleive. We will be replacing about 100 push-o-matic devices and checking all connections for tightness. We will of course address any other issues we find while in there. The guys working on this job have never seen bull-dog equip before.

How many pole positions are in the common backbox, >42?
Will you replace the guts with a new panelboard with individual backboxes. I was in a jurisdiction that would allow the reuse of a old backbox for new panelboard guts (not UL listed together).

Each seperate section has 40 positions in 2 banks. Each section is controlled by 2 contactors, 1 for each bank of 20 devices. As far as I know at this time, we will only be replacing individual devices, and then only about 80 out of 120. (?) We will be checking all terminations to make sure they are secure. Panel schedules are all incorrect but they declined to have us do a new panel schedule.

In pic #3, are you going to replace the GE and FPE breakers?

P.S. The subject of mixing different manufactures breakers in the same enclosure would be a good thread all by it self.

You need to get rid of that aluminum ladder before someone gets hurt.
