Is the Federal Electric Noark load center the same as, similar to, or different from the Fed Pac Stab-lok load center?
The breakers have the same “on/out” orientation, the “centering studs are the same.

"a sun-panel"
Does that mean that it gets so hot it glows?
"pre-floating neutral days"
Do you have any idea what days those where?
The NEC has prohibited re-grounding the neutral since 1923, except for ranges and dryers that use the neutral as the grounding conductor, and for separate buildings. Those exceptions were abandoned in 1996 and 1999.

Well, in my area, the AHJs didn't start requiring floating neutrals in sub panels until about 10 years ago.
Give or take a few years for the various jurisdictions.

I was wondering because my house, 79 use sub-pannel with bonded neutral.
And my frieds house with an addition build around that time also had an combined neutral/ground. That house, orginally built in the 50's, looked like it had a high quality electrical for the times, but the work done since was a real mess. No no romex connectors on the sub-pannel, switched neutral, any correlation between breaker size, wire size, and circuit was completely random.
As I said my house was build in 79. At that time building permits where controlled by the Developement Company (similar to a HOA) and they where mainly concerned with setback requirements and no tar paper siding (C&R dating from 1928). Inspections where done by the local fire department distric whcih had a few paid staff and significant volunteer members at the time.
So inspections where not a strong point. There are not inspection stickers or reports that I have seen.
Now the city (about 1000 residents) control the building permits and uses a moonlighting inspector from a neighboring small city.
Now this house that I have mentioned that I have been doing minor fixup work on (bad lights, leaking faucetts, etc) was finished in 1980 in a nearby growing sub-burb. It is in a very upscale neighborhood.
But I can see many of the materials and construction details are the same as my house. Same GTE/Sylanvia pannels, same ID's for the circuits (NONE), same brand and style of interior locksets, cabinets seem to be from the same custom cabinet shop and same lack of stops on the kitchen and bath sinks.
And one of the things that I am doing is to ID the circuits. It has 320 amp service with 2 main 200 amp pannels one end of the house and a sub-pannel on the other.
Now this house was well "insepcted" at least by the number of stickers that I have seen for plumbing, electrical, and COO.
And I was interested in how the sub-pannel was wired.
Now I did not try digging out any of the wires and with everything in the pannels sonethings where buried and I might be missing something.
The sub-pannel appears to be correctly wired. 4 wire feeder cable. Grounded connected to ground bus bar. Isolated neutral.
BUT at the main pannel that feeds that sub-pannel the ground wire on the feedeer cable was just left unconnected in the pannel.
