Steve,
But it WOULD become a big liability to both label and maintain; the first time someone secures breaker #5 because it's on the marking and gets a shock because he forgot to frisk and it was actually on breaker #6, people will get sued.
This isn't a personal attack on you Steve, but I thought that that was why they made test equipment?.
If a person isn't competent enough to use such gear, should they even be messing with electrical circuits?.
