Was at a seminar the other day. The instructor emphatically stated that any work--replace fuse, connect conductors, in a bus plug--required the bus duct to be shut down.
He also added that if we worked on a fusible disconnect switch, the power ahead of it had to be shut down so there was NO POWER at either the bus plug or disconnect switch.
He could not provide documentation but insisted he was correct.
I don't have a NFPA 70e 2012, but I do have the 2004. I don't see anything in that so I'm looking for some guidance.
I'll be purchasing the 2014 NFPA 70e as soon as it is available.
Thanks,
Tim
