Show windows and track lighting are covered in which NEC section?
Correct Answer:
NEC Section 220.46
Explanation:
The main concept is determining how to size the lighting load for a dwelling. NEC 220.46 provides the method for calculating the dwelling unit lighting load, and it includes common fixed lighting installations such as track lighting alongside other lighting fixtures. This is why it’s the best fit for showing how windows (as part of general lighting considerations) and track lighting are accounted for in load calculations. The other options cover different topics: 408 deals with panelboards and switches, 430 covers motors and motor circuits, and 230.71(B) relates to service equipment/ disconnecting means rather than how lighting loads are calculated. So, the section that specifically addresses calculating the lighting load for a dwelling unit is NEC 220.46.
