For instance, common sizes include 14-, 12-, 10-, 8-, 6-, and 2-gauge wire. The gauge of the wire dictates the amount of current that can safely pass through the electrical wire. Electrical current is measured as ampacity. As a guide, #14 wire is good for 15

Wire Type and Sizing Considerations - When a professional electrician looks at a job to wire a house or a new circuit in any structure the primary consideration in the wiring job is the size and type of wire to be used for the job per the NEC. The same for a pluer
7/8/2020· Typical NEC wire ampacity tables will show allowable maximum currents for different sizes and appliions of wire. Though the melting point of copper theoretically imposes a limit on wire ampacity, the materials commonly employed for insulating conductors melt at temperatures far below the melting point of copper, and so practical ampacity ratings are based on the thermal limits of the
