The electrical code states you can load a breaker to 80% of its capacity. The electrical code also states that, for loading purposes, one receptacle can be treated as one amp. Therefore, by code, a 20 amp breaker can supply 16 receptacles.
The NEC (National Electrical Code) used in the United States has no requirement on the number of receptacles on a 20 amp circuit in a residential setting. The circuit should only service 500 sq. ft. of the dwelling, so a room for example of say 20 feet by 25 feet would be 500 sq. ft. It would require one 20 amp circuit. This circuit could also be used for the lighting load in this room. This is the minimum requirement to meet code and not always the best wiring practice.

How many watts will a 30 amp two pole breaker handle at 240 volts?
30X240=7200
Does a double 50 amp breaker make a 100 amp?
No, a double pole 50 amp breaker protects a 240 volt supply at 50 amps. The number that is on the handle of the breaker is the amperage that the breaker will trip at if an overload occurs on the circuit.
20 amp breaker power verse 15amp breaker power?
A 20 amp breaker can handle up to 20 amps of current before tripping, while a 15 amp breaker can handle up to 15 amps. This means the 20 amp breaker can support heavier electrical loads without tripping compared to the 15 amp breaker. It's important to match the breaker size to the electrical load to prevent overloading and potential hazards.
How many watts can a 20 amp breaker handle per hour?
A 20 amp breaker can handle up to 2400 watts per hour (20 amps x 120 volts = 2400 watts).
What is the difference between a 30 amp and a 40 amp breaker?
A 30 amp breaker is designed to handle a maximum continuous load of 30 amps, while a 40 amp breaker can handle a maximum continuous load of 40 amps. The 40 amp breaker allows for more current to flow through before tripping, making it suitable for higher power requirements compared to the 30 amp breaker. Always consult with a qualified electrician before adjusting or replacing circuit breakers to ensure safety and compliance with electrical codes.
