Based on the 80% rule, how many amps can you run on a 150 amp breaker?

The 80% rule is a guideline used in electrical systems to determine the maximum load that can be safely sustained by a circuit breaker or other electrical components without risk of overheating or tripping. According to this rule, a circuit should not be loaded beyond 80% of its rated capacity for continuous use.

For a 150 amp breaker, you would calculate 80% of 150 amps. This is done through the following calculation:

150 amps x 0.80 = 120 amps.

Therefore, the maximum load that can be continuously run on a 150 amp breaker is 120 amps. This calculation ensures that the electrical system operates safely and reduces the risk of overload, which could potentially cause damage to the circuit or create a safety hazard. Understanding and applying the 80% rule is crucial for ensuring proper load management in any electrical system.
