According to NFPA 99, what is the minimum number of sets of wire required for connecting an initiating device to a junction box?

The correct answer is: 2

The minimum number of sets of wire required for connecting an initiating device to a junction box is two. This requirement is in place to ensure redundancy and reliability in the electrical connections within healthcare facilities. The use of two sets of wire allows for one set to serve as a primary connection while the second set acts as a backup. This redundancy is crucial in healthcare settings, where the failure of an initiating device could lead to critical safety hazards or interruptions in patient care. By requiring a minimum of two wire sets, NFPA 99 helps to ensure that even if one wire set fails or is compromised, the initiating device can still function properly. This emphasis on reliability and safety is a critical aspect of the standards set forth in NFPA 99, which aims to protect patients and healthcare workers in medical facilities.
