A feeder overcurrent device is rated higher than the allowable ampacity of its conductors, with no applicable tap or next-size rule. What is required?
- Reduce the device rating or increase conductor ampacity
- BLeave it because feeders are never protected at their supply end
- CRelabel the conductors with a higher temperature
- DIncrease only the equipment-grounding conductor
Why A is correct
Feeder conductors require overcurrent protection coordinated with their allowable ampacity unless a specific permission applies. Relabeling field insulation or changing an unrelated grounding conductor does not protect undersized current-carrying conductors.
