To wire garage receptacle circuits with #14 does makes no sense either due to the intended use in this kind of area. The table below indicates the current ratings of PVC-insulated single and multicore wiring cables. Using the basic electrical formula "Watts = Volts x Amps," the wire presents the equation Watts = 120 x 20 with a result of Watts = 2,400. Current Draw, Minimum Wire Gauge, Voltage Drop. assuming someone after us may put in the max bulb, the total watts would be 1200, equaling 10 amps. 63 milli-ohms, so at 65 amps, the power loss in each piece of wire will be 65 x 65 x 0. However, 10 gauge wire is the best match wire size. Wire Size Chart and Maximum Amp Ratings. Can 14 gauge wire be. Motors and some other stuff are allowed to go higher but not general use circuits. 8 ft 16 Gauge Wire (AWG) 11. Ask a competent electrician if you’re not sure what wire to use. On the other hand, 14-gauge wire can only handle fifteen. For 14 AWG wire, this works out to about 15 amps of current. However, if you’re installing outlets in a home with many outlets, you should use thicker wires. If it is a 10 amp circuit, then the wire requires 14 gauge. As a guide, #14 wire is good for 15 amps, #12 wire is good for 20. For a visual, it has roughly the same thickness as a dime. that circuit with a 15-amp breaker, as well as wire it with a 14-gauge wire. The proper amperage is determined by the size of the wire, ambient temperature, number of wires installed together, the types and number of electrical devices connected on a circuit.
