Current is measured in amperes or “amps.” You must use the correct size wire for the current (load) requirement of the circuit to prevent the wire from overheating. The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor Ampacity based on NEC ® Table (B) (16) (formerly Table) Allowable Ampacities of Insulated Conductors Rated Up to and Including Volts,° through°C (° through °F), Not More Than Three Current-Carrying Conductors in Raceway, Cable, or Earth (Directly Buried), Based on Ambient Temperature of°C (86°F) Based on NEC Table (C)(67) Ampacities of Insulated Single Copper Conductor Cables Triplexed in Air Based on Conductor Temperatures of°C (°F) and °C (°F) and Ambient Air Temperature of°C (°F)Based on NEC Table (C)(68) Ampacities of an Insulated Single Aluminum Conductor Cables Triplexed in Air Based on The wire size chart below shows allowable ampacities of insulated conductors rated up to and including Volts,°C through°C (°F through °F), not more than three current-carrying conductors in raceway, cable, or earth (directly buried), based on ambient air temperature of°C (86°F).
