What is the maximum nominal voltage permitted for a luminaire installed in a motel room?

The maximum nominal voltage permitted for a luminaire installed in a motel room is 120 V because this voltage level adheres to safety and regulatory standards commonly applied in residential and similar commercial settings. In the United States, 120 V is the standard voltage for most household fixtures and equipment, making it suitable for use in motel rooms where safety and compatibility with existing electrical systems are critical. Low-voltage electric lighting configurations, including those often found in hospitality environments like motels, utilize this voltage to ensure that electrical installations are safe for occupants while providing sufficient illumination.

Higher voltage levels, such as 150 V, 240 V, or 277 V, are typically used in different contexts that require more power, often for industrial applications or specific types of commercial lighting, which are not typically appropriate for the residential setup of a motel room. Using fixtures rated for higher voltages in such environments could pose unnecessary risks and complications due to increased electrical hazards.
