Four AWG insulated conductors enter a cabinet through a raceway. What protection is generally required at the raceway end?
- AOnly additional pulling lubricant for the wiring method and location described
- BA neutral bonding screw
- CA sharp threaded edge
- A fitting that protects conductors from abrasion
Why D is correct
Where raceways contain 4 AWG or larger insulated conductors, an identified smooth insulating surface or fitting protects insulation from abrasion at the raceway termination.
