A few years ago, I had some extensive repairs done to the outside of my house. A lot of the various crews just came and went on their own time with no notice, and I often didn't know they were here until I heard construction noises outside.So you are suggesting the electrician is NOT going to turn the breaker off that feeds power to that line? I know there are A LOT of stupid people out there that wouldn't turn the power off, but an electrician would. With the breaker off to that outlet, there is NO risk to their health.
Well one day the electricians showed up and just started working on their jobs. I realized they were here about three hours into their work. All the breakers are inside my house in a mudroom. They didn't turn anything off (or even asking me to turn anything off) to do their work. Once I realized they were outside, I asked them if they needed me to shut off the power to where they were, and they responded, "No we just finished."
They rewired multiple exterior receptacles and lights, all while the circuits were hot. I guess if you're really skilled and experienced you have no fear doing this. Not me, though.
