A 14-gauge wire is typically rated for a maximum of 15 amps for general household circuits. To calculate the wattage it can handle, you multiply the amperage by the voltage. In a standard 120-volt system, a 14-gauge wire can safely carry about 1,800 watts (15 amps x 120 volts). However, it's important to consider factors like the type of circuit and local electrical codes, which may impose additional limitations.

A 14/3 GA Romex type wire is rated at 15 Amps, and by regulation can only be used in home applications. You can use 14/3 for a 240 V application, in which case it would be capable of carrying 3600 Watts. If you use the wire with 120 volts, it can only handle 1800 watts. If you are not experienced with electrical wiring, contact a licensed electrician to assist you with your needs.
A 110V wire can typically carry around 15-20 amps safely, depending on the wire gauge and insulation. Using the formula Watts = Volts x Amps, this would allow the wire to carry up to 1650-2200 watts. However, it's always recommended to consult a professional electrician for specific calculations and safety considerations.
A 12 AWG wire is typically rated for 20 amps in standard household wiring. At 240 volts, this wire can safely carry up to 20 amps of current.
