What is the minimum length for raceway or cable for tap conductors to recessed luminaires?

The minimum length for raceway or cable for tap conductors to recessed luminaires is specified as 18 inches in the National Electrical Code. This requirement ensures a safe and accessible distance for connections, reducing the risk of strain on the conductors and giving adequate space for maintenance and repair. An 18-inch length is enough to provide flexibility and accommodate the installation needs of recessed lighting fixtures, allowing for proper installation practices while adhering to safety standards. This specification is designed to promote better electrical performance and safety in residential and commercial applications involving recessed luminaires.
