An electric motor draws 14.5 amps, using a 9-wire bundle. What gage wire having a 200ºC temperature rating is appropriate?

Choosing the appropriate gauge of wire for an electrical application is crucial for ensuring safety and efficiency. In this scenario, we are looking for the correct gauge wire that can handle a current draw of 14.5 amps.

The selection of 14-gage wire is suitable for this application because, under the National Electrical Code (NEC), 14-gage wire is rated for a maximum of 15 amps, which is sufficient for the 14.5 amps that the motor draws. It allows for a small margin of safety and compliance with wire gauge standards.

Moreover, the consideration of a circuit breaker is important as it acts as a protective device for the wiring and the load. While a 15 amp circuit breaker pairs well with 14-gage wire, it is also appropriate since circuit breakers should provide protection slightly above the maximum expected load to avoid nuisance tripping during normal operation, without exceeding the wire’s rated capacity.

Choosing a wire that is too large for the application (such as 12-gage or 10-gage) would not be ideal, as it may not provide the necessary protection for lower current applications and could lead to improper tripping of circuit breakers designated for larger amperages. Thus, 14-gage wire with a
