Overcurrent Protection for Conductors & Equipment
Overcurrent Protection for Conductors & Equipment

This self-paced online course explains overcurrent protection requirements of the National Electrical Code ®. The purpose of overcurrent protection for conductors and equipment is to open the circuit if the current reaches a value that will cause an excessive or dangerous temperature in conductors or conductor insulation.


Students will learn to:



  • Identify the purpose of overcurrent protection.

  • Explain the difference between overcurrent and overload.

  • Explain the difference between a short circuit and a ground fault.

  • Understand how the minimum ratings are determined for various items.

  • Explain aspects of the protection of conductors.

  • Explain the factors involved in the location of overcurrent protection.

  • Explain tap rules.

  • Identify how other equipment is protected, including panelboards, motor control centers, transformers and welders.

  • Identify special protection requirements for motors and refrigeration equipment.
