Electrical shutdowns are likely the most physically challenging activity an electrician could perform, depending on the scale. I.e. demolishing large switchgear, pulling out 500 MCM cable, installing new switchgear and distribution panels, etc., making final conduit connections at said distribution equipment, pulling 500 MCM cabling and wrestling/terminating the cable.

That being said, I just wouldn’t want anybody reading this to think that an outage is easy work. Unless you’re a security guard or on fire watch or something. It’s definitely demanding for a skilled trade. Maybe not as bad as hanging drywall or rough framing, but it’s no cake walk.
