What is the minimum wire size for tracer wire adjacent to underground nonmetallic gas piping?

• A. 16 AWG
• B. 18 AWG
• C. 20 AWG
• D. 22 AWG

Answer: (B)

The minimum wire size for tracer wire adjacent to underground nonmetallic gas piping is 18 AWG. This size is significant for ensuring both safety and compliance with relevant standards. A wire gauge of 18 AWG provides a good balance between adequate conductivity and durability, ensuring the wire can effectively transmit signals for locating the piping without being prone to damage from environmental conditions or installation stress. Using a wire that is too thin (like a 20 AWG or 22 AWG) could result in increased resistance, which may lead to signal loss and hinder the functionality of the tracer wire, making it harder to locate the gas piping when needed. Conversely, using a larger size, like 16 AWG, might be unnecessary and could complicate installation without providing additional benefits for this application. Thus, 18 AWG is the appropriate minimum size that meets industry requirements and functional needs.
