IF I have to work on a Baker/Perry...
AND it MIGHT be hot...
I make sure that the scaffold is on rubber - at the base.
But, generally, anything is quasi-safe IF un-energized.
Just another reason that causes me to work COLD virtually all of the time.
I only work hot when pulling voltage and amps -- on my Fluke.

You NEVER see a carpenter inviting others to walk upon UNCOMPLETED framing...
So why in hell are electricians expected to flip on uncompleted, un-tested, un-ready work?
I even have to fight my own crews over this. They look upon their OWN completed work without regard to the overall status of the project.
As for me: I see no need to heat up a given panel to show that the feeder is okay. Nor to heat up a branch circuit to show that j-man x did a fine job.
I only want to heat up all of the branches after the errors are corrected.
'Nuff said.
