110.8 Says:
(1) Energized Electrical Conductors and Circuit Parts
— Safe Work Condition. Energized electrical conductors
and circuit parts to which an employee might be exposed
shall be put into an electrically safe work condition before
an employee works within the Limited Approach Boundary
of those conductors or parts, unless work on energized
components can be justified according to 130.1.

If I read this correctly I could not do the following tasks without justification:
1. Change out an energized edison base light bulb.
2. For a control panel with 120VAC energized parts I could not change out a plug in relay within 3-1/2' of the energized parts or connect a laptop to a PLC
in that enclosure.
3. Change out flourescent bulbs that are energized.

[color="RoyalBlue"][/color]Is this a correct intrepretation?
