Which term refers to the maximum amount of current a conductor can handle continuously?

The term that refers to the maximum amount of current a conductor can handle continuously is "Ampacity." Ampacity is a critical parameter in electrical installations because it defines the safe current-carrying capacity of a conductor under specified conditions. This capacity is influenced by factors such as the conductor material, temperature, insulation type, and installation environment.

Understanding ampacity is vital for preventing overheating and potential conductor failure, which can lead to fires or electrical hazards. Properly sizing a conductor according to its ampacity ensures that it can safely carry the expected load without exceeding its current limit, thus maintaining safety and system reliability.

The other options do not apply in this scenario: voltage capacity relates to the maximum voltage a conductor can handle, wattage rating refers to the total power a device or circuit can use (expressed in watts, which is the product of voltage and current), and current rating is a more general term that does not specifically denote the continuous capability defined by ampacity.
