# How many watts can you put on a 20 amp circuit?

## What is the maximum load power for a 20 amp circuit?

Allowable Breaker Load The NEC does specify that a circuit breaker shouldn’t handle more than 80 percent of the load for which it is rated unless the breaker is labeled otherwise. By this standard, the total current draw on a 20-amp circuit shouldn’t exceed 16 amps.

How many 40 watt bulbs can be on a 20 amp circuit?

You can put up to 40 lights (based on 50 watt light) on a 20 amp breaker.

How Many Watts Can a 20-Amp Breaker Handle? For standard 120-volt service, a 20-amp breaker can support up to 2,400 watts on a single circuit. You can put up to 40 lights (based on 50 watt light) on a 20 amp breaker.

#### Can outlets and lights be on the same circuit?

Basic answer to your question of can a mixture of lights and receptacles be installed on a single circuit is yes. Check with local authorities on those limitations but yes it can be done. The groundwork for all AC circuits which are wired in what is known as parallel circuitry.

A rule of thumb is to factor a maximum draw of 1.5 amps to each receptacle, which means you can put 10 outlets on a 20-amp circuit.

## How many watts can a 20 amp circuit support?

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.

## How many watts can a 20 amp breaker handle?

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.

How many amps can a 120 volt circuit draw?

For safety, the total draw on the circuit shouldn’t exceed 16 amps at any one time, which translates to a maximum power draw of 1,920 watts on a conventional 120-volt circuit, even though the breaker won’t trip until the power draw exceeds 2,400 watts.

### Is there a limit to how many receptacles you can put on a 20 amp circuit?

There is no limit to the number of receptacles that you can place on a 20-amp circuit, according to the National Electrical Code. Therefore, one of the best ways to prevent overloading the breaker is only to run appliances that draw less current than the breaker can handle.
