Where do you live? In a lot of municipalities any out-of-code work can remain unless they are actively touching that part of the system. For instance, if you had ungrounded outlets in your house, but were just getting a drop for a ceiling fan you wouldn't have to install grounds as part of that work. So they must have been having to touch all those components anyway.

  Just trying to give benefit of the doubt. I suspect this was a tack-on.

If you're mounting EV charger, or heat pump you'd me most likely running separate circuit off main box for them. Which means you have to fix the main box. Which is most expensive part to fix.

  Most of the time the main box is good enough. Fuses are still legal. There are a few boxes that are safety hazards, but if you have one you should replace it even if not planning any other work (some circuit breakers don't trip when overloaded!).

    Hello, Federal Pioneer 15A Stab-Lok blue breakers (old style, without the holes) here. I can personally confirm their potential for not tripping when overloaded, along with the smouldering outcome...

Almost for sure that's what happened to the OP as he was having an external disconnect, so the entire panel got depowered + likely big lines were run for whatever he needed the disconnect for. There's sometime exceptions for Solar now that don't require full upgrades, but some cities don't give a fuck. The US is way worst about this than most other places though. Here they inspect your insulator, lead-in wires, meter, and distribution panel and then ask what if any problems you are having (they is the power company) every four years. Mostly the electrician/contractor does the work and there's no inspection of that.
