Last Updated Apr 13, 2020 2:47:38 AM ET
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.
