Which NEC section covers windows and track lighting?

• A. NEC Article 408
• B. NEC Section 600.5(A)
• C. NEC Section 220.46
• D. NEC Article 430

Answer: (C)

Calculating the lighting load for feeders and services is the concept being tested. NEC 220.46 provides the specific method for sizing the lighting load in dwelling units, which includes how to account for different lighting configurations such as track lighting. This section sets the rules for determining the total lighting load that the service must support, using the appropriate unit loads (and any applicable adjustments) so the feeder and service can be sized correctly. Track lighting is one of the lighting configurations that contributes to that load, so this section is the relevant reference for calculating it. The other options don’t address lighting-load calculations for dwelling units. Article 408 deals with panels and switchgear, Section 600.5(A) concerns signs, and Article 430 covers motors and motor controls.
