Who must have access to the calculated available fault current documentation prior to installation?

• A. The Authority Having Jurisdiction (AHJ)
• B. The electrical contractor only
• C. The equipment owner only
• D. The public relations team

Answer: (A)

The Authority Having Jurisdiction (AHJ) must have access to the calculated available fault current documentation before installation. This documentation shows the maximum short-circuit current the system could experience, which is essential for selecting properly rated protective devices and equipment. The AHJ reviews these calculations to verify that the design complies with electrical codes and safety standards, ensures correct coordination of protection, and prevents equipment damage or unsafe conditions once the system is energized. While the contractor, equipment owner, or other stakeholders may use the data, it is the AHJ’s role to review and approve it as part of the permitting and compliance process.
