A made-up,live panel is an invitation for carpenters to flip breakers. No matter how many signs you put on it.
oh yes, ga.sparky56.
i've come to two avenues with this one...
a)
place an orange 77 on the hots just before entering breakers, and visit the panel for connection repeatedly througout the job or..
b)
use a small means of id for circuits that are ok to be on, i use a small magic marker 'dot' alongside my panel sched.
being confronted one can alwyas point out said 'dot' system , and those circuits activated by meddling hands...
just a little bit, just a little bit... fla sparkey
