Hi, thanks for that. Im not an electrician but I work for the IBEW! In the given example, electricians in my state have years of training and on the job experience*. To a non-electrician like me, my thinking is that they can control their environment- cut off power, and have an idea of what they’re going into at a given time. You don’t know what is behind the door at a domestic violence call.
ETA: *before earning a license. And FWIW, I’m not the one downvote; I was the second upvote. People be out hear voting their opinions, not discussions.
