Which NEC section covers Windows and track lighting?

Which NEC section covers Windows and track lighting?

• A. NEC Section 600.5(A)
• B. NEC Article 430
• C. NEC Section 230.71(B)
• D. NEC Section 220.46

Answer: (D)

The key idea here is where to find the rule for calculating the lighting load in a dwelling, including fixtures like track lighting. NEC 220.46 is the part of the code that lays out how to compute the lighting load used to size feeders and the service, and it explicitly covers typical lighting types such as track lighting as part of that calculation. Other options don’t address how to determine or size the lighting load: one option deals with general luminaire requirements rather than load calculations, another covers motors, and another concerns service disconnects. So the section that directly covers calculating the lighting load, including track lighting, is the correct reference.
