Exception. A conductor size 8 AWG or larger is not required to be marked in conduit bodies that contain no splices or unused hubs.

(2)

Identification shall encircle the conductor and shall be accomplished by one of the following:

a.

stripping the insulation or covering from the entire exposed length;

b.

coloring the insulation or covering green at the termination; or

c.

marking the insulation or covering with green tape or green adhesive labels at the termination.

300.3(C)(1) Conductors of different systems. Feeders and branch circuits of solidly grounded wye electric systems that operate at less than 150 volts to the ground may not occupy the same wireway, raceway, junction box, pull box, outlet box, or enclosure with feeders or branch circuits of solidly grounded wye electric systems that operate at more than 150 volts to the ground.
