Can NMD wire be installed to an outside gas lamp?

Yes
No
Only if the lamp is direct spark
Yes if it is 14 AWG wire

The correct answer is: No

NMD wire, which is often used for indoor applications, is not suitable for installation in outdoor environments due to its vulnerability to moisture, UV rays, and extreme temperatures. Outdoor installations require wiring that is specifically rated for such conditions, typically involving a product that is moisture-resistant and can withstand exposure to outdoor elements. Thus, the choice indicating that NMD wire cannot be installed to an outside gas lamp is correct. It's important to use the proper wiring type for outdoor applications, such as UF (Underground Feeder) wire or other outdoor-rated wires, ensuring safety and compliance with electrical codes.
