What does the term 'Bonding Jumper' refer to in NFPA 54?

A voltage regulator
An insulator
A reliable conductor ensuring electrical conductivity between metal parts
A safety switch

The correct answer is: A reliable conductor ensuring electrical conductivity between metal parts

The term 'Bonding Jumper' in NFPA 54 refers to a reliable conductor that ensures electrical conductivity between metal parts. This is crucial in gas fitting because it provides a path for electrical current to safely flow back to the ground in the event of a fault, which helps prevent electric shock and fires. Proper bonding is essential for enhancing safety by reducing electrical hazards, especially in installations where different conductive components may come into contact with one another. In various gas appliance installations, ensuring that all metal components are electrically bonded protects both the equipment and those who may be nearby. The other choices don't align with the definition provided by NFPA 54. A voltage regulator manages voltage levels but doesn't address safety in terms of grounding and bonding. An insulator, while important in preventing electrical flow, serves to separate conductive parts rather than connect them for safety purposes. A safety switch is related to interrupting power under specific conditions but does not play the role of ensuring conductivity between metal parts. Therefore, understanding the function of a bonding jumper is essential for safe gas fitting practices.
