Well, the best way to know if you did it right the first time is to KNOW HOW to do it right! :hey:
For most electricians, can't say all, working hot circuits is never a matter of choice, but necessity.
I have made some modifications to industrial control panels while hot, but ONLY because the
production equipment could not be shut down. Working 480 circuits hot will definitely make
you use more caution, let alone higher potentials. I wonder if that guy ever worked on any 220KV?
Not for long!
My advice is to always turn off the breaker. I mean, why in the world not? I will always do this when possible,
even on 120V equipment. Reminds me of those guys on TV letting themselves get tasered, just so they will
"know what it feels like." That's just a bunch of macho BS.
I don't have to take a 7.62 to know it will kill me!
just my 0.14RMB
