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. ~Seth
