About Lesson

Article 240 of the NEC provides guidelines for overcurrent protection, including requirements for conductors, equipment, and devices. Overcurrent protection is designed to protect conductors and equipment from damage due to excessive current flow.

One of the key requirements of Article 240 is that conductors must be protected from overcurrents by devices such as fuses or circuit breakers. The overcurrent protection must be coordinated so that the downstream device is the one to open in case of an overload or short circuit.

Another important requirement is that the overcurrent protection device must be rated for the maximum amperage of the conductor that it is protecting. This is intended to ensure that the conductor is not exposed to excessive current that could cause damage or create a safety hazard.
