What is the required clearance between a non-IC light and nearby insulation?

The required clearance between a non-IC (non-Insulation Contact) light fixture and nearby insulation is 3 inches. This requirement is in place to prevent the risk of fire hazards that can arise due to the heat generated by non-IC fixtures when they are surrounded by insulation materials. Non-IC fixtures are designed to allow heat to dissipate, and when insulation is placed too close, it can trap heat, leading to an increased risk of ignition.

Maintaining a clearance of 3 inches ensures that there is enough space for heat to escape safely, protecting both the fixture and the surrounding materials from potential overheating. This guideline is critical for ensuring safety and compliance with electrical codes. Proper clearance not only helps in preventing fires but also increases the longevity and performance of the lighting fixture.
