What is the minimum length that tap conductors for recessed lighting fixtures must be?

The minimum length for tap conductors for recessed lighting fixtures is critical to ensure proper installation and safety. The requirement of 18 inches allows for sufficient conductor length, making it easier to service, connect, or modify lighting fixtures in the future while also considering the need to maintain proper electrical codes and standards.

This length helps ensure that the conductors are accessible while minimizing the risk of strain or damage to the wiring connections due to tension or twisting. It also provides enough flexibility to accommodate different installation scenarios, where fixtures may need to be adjusted or where junction boxes are situated at varying distances.

In contrast, shorter lengths would not provide adequate flexibility or accessibility, compromising ease of maintenance and potential safety. Therefore, the code specifies 18 inches as the minimum required length to establish safe and effective connections for recessed lighting fixtures.
