Which article addresses Optional Standby Systems in the NEC?

The National Electrical Code (NEC) designates Article 702 to address Optional Standby Systems. This article outlines the requirements and guidelines for systems that provide backup power in case of utility power failure, ensuring that these systems are installed safely and correctly.

Optional Standby Systems differ from other types of power systems, such as emergency systems or legally required standby systems, as they are utilized for convenience rather than for critical life safety applications. Article 702 provides specific provisions regarding the installation, maintenance, and operation of these systems, including considerations for transfer switches, load management, and proper generator use to facilitate safe power restoration.

This understanding is critical for electricians and contractors since it affects how they approach design, installation, and compliance with safety standards when implementing backup power solutions. Following NEC guidelines helps ensure that Optional Standby Systems function effectively when needed.
