# FAQ: How many watts can a 20 amp circuit handle?

## What is the maximum wattage for a 20 amp circuit?

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.

## What can a 20 amp circuit support?

A 20 – amp breakers can support up to 2,400 watt on a single circuit. The safe maximum for a 20 – amp circuit is 1,920 watt, but circuits should not be loaded to more than 80 percent of their maximum capacity.
