You observe #6-gauge copper wires entering a service box with two 60 A fuses inside. How should you report the service size?

The service size should be reported based on the capacity of the fuses in the service box, which are rated at 60 amps each. In this case, there are two 60 A fuses present in the service box. When assessing the overall service size, it is essential to consider the lower rating of the protective devices, such as fuses, as they dictate the maximum current that can safely flow through the service.

While the gauge of the wire may indicate it could handle a higher electrical load, the actual service capability must align with the fuse ratings to ensure safety and proper function. Therefore, even though the wire size suggests potentially larger capacities, the effective service size must be reported as 60 amps based on the fuses. This ensures that the reported service size reflects the limitations established by the fuses, which protect the wiring system from overload and potential hazards.
