I can understand both sides of this argument. Have worked many times hot. Have been shocked the worst by 120. If I can, I shut down any ckt I work on except during troubleshooting. I do NOT allow my apprentices to work hot. Sometimes you just have to tell the office types tough s*** the light are going off or the power is going down. I try to be diplomatic about it but safety come first. The only real reason to work hot is when it is absolutly necessary to do so. No office or store location or house has any reason to work hot because of potential hazards of shuting down the power.
Industrial areas can be a different story.
