Load Calculations

Introduction

Services and Feeders

The rules covering service and feeder conductors and overcurrent devices are very similar to the rules for branch circuits and are found in the following sections. The wording varies slightly, but the basis is still the load calculation from Article 220.

Section 215.2 covers feeder conductor ampacity. Section 215.3 covers feeder overcurrent device ratings. Section 230.42 covers service conductor ampacity. Section 230.79 covers sizing of disconnecting means in service equipment. Section 230.90 covers service overcurrent device ratings.
