CBs fed from different source can be installed in same enclosure as per NEC?

[TMMB]

A lighting pole has 3 floodlights powered by a regular power source and 2 floodlights powered by another emergency power source. Is it permissible to combine the main circuits breakers for both power source and the outgoing circuit breakers in same fuse box?
Is it possible to install circuit breakers for two different sources in the same fuse box

I think the answer is yes to both questions provided none of these conductors are service conductors

When you say, "powered by another emergency power source." what does that mean? Do you have a generator, with separate breakers for normal and emergency, separate panels for normal and emergency and no batteries in your emergency lighting? If so, then not only can you NOT combine the breakers, the wiring needs to be separated by a raceway per article 700

Why would lighting on a pole ever be "emergency" as defined by the NEC.

There may be other situations, but healthcare is one. They are required to have emergency lighting along at least one path of egress to the edge of the property.

we have 2 power supply one normal and the other by UPS, so my Q is , it is possible to have 2 different feeders from 2 different power supply in the same enclosure?

See 700.10(B)
Is the UPS actually an emergency system or is it optional standby?

to keep power available always

But you would need to know if it's an article 700 "Emergency" system, an article 701 "Legally Required" system, or an article 702 "Optional Standby" System.
The rules are different for the type system you have. If you have an article 700 system the pole will need to meet one of the conditions of 700.10(B)

The panel needs needs new labeling that states there's two different /Multiple sources of power in enclosure!

(sorry no NFPA for exact reference)

 

[TMMB]

to clarify my Q, KINDLY, REVIEW THE ATTACHED, MY CLEAR Q IS , IT IS PERMISSABLE TO INSTALL MULTIBLE C.Bs feeding from different sources, please, helping me t take deaccession

 

[petersonra]

This looks to me like you are cross connecting some of the breakers.

It appears the two pole breaker on the left does not have anything connected to one of its poles as well.

I would want to see a schematic.
