Are you mistaking your interactions with low level trades roles (the guy who's making bank fixing power sockets on the weekend) with say, the people maintaining factory electrical systems? or designing them?
Nah more like the guy who wires up the whole house.
Factory electrical systems are on another level than your typical 110V AC. But given what I know I would say that the factory electrician sits right at the borderline between comparable to SWE and anyone can learn it.
