What kind of switch is that? Nothing can stop an "electrician" from
wiring it wrong anyway.
Had a plumber in my house replacing my lift system pump, which has a
wall switch controlling the power.
Told him I'd flip the breaker for safety, and run a extension cord for
light.
"Nah, I'll just flip the switch." He got slightly zapped, because the
damn switch is wired backwards. Had me flip the breaker.
I never trust that a switch is wired correctly.
