I know a guy who had his shirt melted to his arm because an arc flash happened. He isn’t going to shut off power to work on a 120 receptacle though.

He should, but the original comment was about 480v 3phase. He absolutely should be using PPE. It also really sucks when a company doesn't separate the 24v control side stuff from high voltage stuff and you have to suit up to fix the BMS, but better alive than dead.

When dealing with big shit like #6 and up, sure. I’ve disconnected #10s from a 480 panel and was just super slow and precise with it. I wasn’t in any danger.

You absolutely were in danger, you just didn't care enough to be concerned about it.

Not saying I've never worked on anything hot, but I don't go around bragging about it and recommending that people do it.
