I find that electrical panelboards, busways, transfer switches, etc. are
often put in the category of things that don't need maintenance or
routine inspections. Big deal if you can start your fancy generator once
a month (I prefer on-load weekly) but the in between stuff is in
disrepair or full of mice. Even a simple dusty transfer switch could arc
weld itself to once side of the contacts.
