What is the maximum allowable current when using AWG #14 jacketed wire for a branch circuit?

15 amps
20 amps
25 amps
30 amps

The correct answer is: 20 amps

The maximum allowable current for AWG #14 jacketed wire in a branch circuit is 15 amps. This is based on the National Electrical Code (NEC), which specifies that conductors must be selected according to the amount of current they are expected to carry safely without overheating. AWG #14 wire is typically rated for a maximum of 15 amps. The reasoning behind this rating is tied to the wire's ability to dissipate heat generated by electrical resistance. If the current exceeds the rated maximum, it can cause overheating, which poses a fire hazard. Therefore, it is essential to use the correct wire gauge for the current load in order to ensure safety and compliance with regulations. In contrast, options suggesting higher amperages for AWG #14 wire exceed the safe limits established by the NEC and could lead to serious safety hazards. Always refer to relevant safety codes and standards to guide the choice of wire for electrical installations.
