What requirements does Article 215 of the National Electrical Code provide for feeders?

Article 215 of the National Electrical Code (NEC) outlines comprehensive requirements for feeders, which are the conductors that carry electrical power from a service or transformer to a distribution point. This article is pivotal because it encompasses multiple critical aspects of feeder installation, including installation requirements, overcurrent protection, and specifications for minimum size and ampacity of conductors.

The inclusion of installation requirements ensures that feeders are set up correctly according to standards, enhancing both safety and functionality. Overcurrent protection is vital to prevent excessive current flow that can lead to overheating or even fire, which underscores the importance of having protective measures in place. Furthermore, the requirements for minimum size and ampacity are essential for ensuring that conductors can safely handle the intended load without risk of damage or failure.

Combining these elements, Article 215 serves as a thorough guideline for electricians and contractors, ensuring that all necessary precautions and standards are adhered to in the installation of feeders. Therefore, the option that states all of the above requirements is the most accurate representation of what Article 215 addresses.
