Can NMD wire be installed to an outside gas lamp?

• A. Yes
• B. No
• C. Only if the lamp is direct spark
• D. Yes if it is 14 AWG wire

Answer: (B)

NMD wire, often referred to as non-metallic sheathed cable, is designed for indoor use and is not rated for exposure to the elements, which makes its installation in outside applications, such as on an outdoor gas lamp, inappropriate. Gas lamps, being exposed to outdoor conditions, could lead to moisture infiltration or other environmental factors that compromise the integrity of NMD wire. In addition, electrical codes and standards typically recommend using conduit or other methods specifically designed for outdoor wiring to protect against environmental damage and enhance safety. The fact that this installation is for an outdoor application means using wire that is actively rated for such conditions is essential, which NMD wire does not provide. Choosing to use NMD wire for this purpose could result in potential hazards, including electrical shorts or even fires, due to the unsuitability of the wire for outdoor use. Therefore, the correct stance is that NMD wire cannot be installed on an outside gas lamp.
