For standard 120-volt service, a 20-amp breaker can support up to 2,400 watts on a single circuit. However, circuits should not be loaded to greater than 80 percent of their maximum capacity for long periods, which makes 1,920 watts the safe maximum for a 20-amp circuit.
Running a circuit near its maximum capacity for long periods can cause the wiring and connections to become warm and may trip the circuit breaker. If a breaker trips repeatedly, appliances should be moved to other circuits to reduce the load on the affected circuit. Constant overloading can lead to damage and increase the risk of fire.Learn More
Watts are units of electrical power and amps are units of electrical currents. They cannot be converted into each other. However, electrical power is equal to current times the voltage of an electrical source, which means that one watt is equal to an amp multiplied by a volt.Full Answer >
According to Home Depot, a 20-amp outlet is a higher powered outlet commonly used in areas of the house where high-current electrical devices are used. Kitchens often have 20-amp outlets to power small appliances.Full Answer >
A 30-amp breaker does not operate safely with a 12-gauge wire. The minimum wire size that is allowable for use with a 30-amp breaker is 10 gauge.Full Answer >
The terms watts and ohms refer to different electrical principles, so there is no direct way to convert between them. A watt is a measure of power, and an ohm is a measure of resistance. A voltage source produces power, while a given load absorbs it.Full Answer >
