Would anyone here change a lightswitch without turning the power off? I'm sure they did this when they changed a lightswitch at my shop. To isolate the circuit, they would have had to go down 2 storeys to the DB in the cellar. Is this sort of thing heard of?
Also, what's the deal with changing light bulbs in commercial premises? Do electronic ballasts wear out? They came the other day to change bulbs in a few lights and swapped a few electronic fittings for ones with starter motors
I didnt think they used these any more, and i thought electronic fittings lasted forever (within reason
)
