8 NEC Basic Feeder Circuit Sizing Requirements

 · The rating of the overcurrent protection for a feeder circuit must be at least the sum of the non-continuous load +125% of the continuous load, unless the overcurrent device is -rated. Because the rating of the overcurrent protection determines the rating of the branch circuit (Article 210.3), the branch circuit must be sized for the non-continuous load +125% of the continuous load.

Protection of Lines or Feeder | Electrical4U

 · Protection of Lines or Feeder. October 25, 2020. February 24, 2012. by Electrical4U. As the length of electrical power transmission line is generally long enough and it runs through open atmosphere, the probability of occurring fault in electrical power transmission line is much higher than that of electrical power transformers and alternators.
