What is the minimum distance from a recessed luminaire to an outlet box containing tap supply conductors?

The minimum distance from a recessed luminaire to an outlet box containing tap supply conductors is indeed 1 foot according to the National Electrical Code (NEC) guidelines. This requirement is in place to ensure safety and minimize the risk of overheating or electrical failures.

Recessed luminaires are often installed in ceilings, and having them too close to an outlet box with tap conductors could pose a hazard due to heat dissipation and potential electrical arcing. By maintaining at least a 1-foot separation, you help ensure that the heat generated by the luminaire does not negatively affect the tap conductors, which could compromise their insulation and lead to short circuits or fires.

This distance allows adequate air circulation and reduces the risk of degrading the conductors below the outlet box. It is also a way to comply with manufacturer specifications and local amendments to the NEC, which may emphasize safer installation practices. The requirement assists in promoting overall electrical safety in residential and commercial installations.
