What is the maximum rated load for a 15 amp circuit at 120 volts?

1800 watts
1200 watts
600 watts
1000 watts

The correct answer is: 1800 watts

The maximum rated load for a 15 amp circuit at 120 volts can be determined using the formula for electrical power, which is Power (Watts) = Voltage (Volts) × Current (Amperes). In this case, the circuit operates at 120 volts and has a current rating of 15 amps. When you plug in the values, it becomes: Power = 120 volts × 15 amps = 1800 watts. This calculation shows that the maximum load, or power consumption allowable on a 15 amp circuit at 120 volts, is indeed 1800 watts. This is important in ensuring safety and preventing circuit overloads in electrical systems. A load exceeding this maximum could result in overheating and potentially cause the circuit breaker to trip or could result in fire hazards. The correct answer highlights the significance of adhering to power ratings when designing or troubleshooting electrical systems to maintain safety standards and system reliability.
