The proper application of overcurrent protection rules for air-conditioning and refrigeration equipment can be made relatively easy by following a few basic steps.
Overcurrent protection for motors and motor circuits is a little different than the rules for conductors as specified in Article 240, because motor loads have different characteristics than general lighting and other loads.
Electrical inspectors involved with aerial high voltage facilities frequently have to determine whether electrical conductors are in compliance with the National Electrical Safety Code (NESC).
This article will focus on ground-fault circuit-interrupter (GFCI) protection for persons and ground-fault protection of electrical equipment (GFP).
What are the guidelines for determining whether or not a person is a good electrical inspector? Qualifications for becoming an electrical inspector vary greatly.
