How do circuit breakers differs from fuses? fuses cannot be reused while circuit breakers can be reused over and over
again. Circuit breakers are used to protect homes and devices against
overcurrent and short-circuiting while fuses protect devices and homes
against overloading only.


The NEC permits a motor to exceed its nameplate full 125%
load current of ________ if it has a service factor of 1.15 or
greater, and has a temperature rise of less than 40
Celsius or 104 F.




what are the steps used to identify the correct 1. Understand the Circuit
conditions that will trip a circuit breaker? 2. Review Circuit Breaker Specifications
3. Determine Overload Conditions
4. Consider Short Circuit Scenarios
5. Study Trip Curves
6. Perform Calculations
7. Test Under Controlled Conditions
8. Consider Environmental Factors
9. Review Standards and Codes
10. Verify the trip arm rotates smoothly
