True or False: Manufacturers may require that high-voltage portions for lighting enclosures be mounted in the upper right hand corner of an enclosure to conform with NEC requirements to keep low and high-voltage conductors separate.

• A. True
• B. Not sure
• C. Cannot be determined
• D. False

Answer: (A)

Keep high-voltage and low-voltage conductors physically apart inside enclosures. The NEC requires separating conductors of different voltages to reduce the risk of arcing, interference, and unwanted heating, and it often relies on barriers or partitioning to maintain safe distances. Because of this, manufacturers sometimes specify mounting locations for high-voltage portions within an enclosure—such as the upper right-hand corner—to help ensure a clear separation from low-voltage wiring, simplify routing, and improve serviceability. The statement reflects a common, permissible practice aligned with NEC goals of keeping conductors apart, even though the exact corner isn’t a universal NEC directive.
