Answer:
A 15-amp breaker typically trips when the current exceeds 15 amps.
Reasoning:
A 15-amp breaker is designed to protect circuits from overcurrents. If the current surpasses 15 amps, the breaker interrupts the circuit to prevent overheating and potential hazards, ensuring safety.
FAQs:
Q: What is the purpose of a 15-amp breaker?
A: To protect circuits from currents exceeding 15 amps.
Q: Can I use devices drawing more than 15 amps on a 15-amp circuit?
A: No, it may cause the breaker to trip, leading to power interruptions.
Q: How do I calculate the current for my appliances? ‘
A: Divide the wattage by the voltage; ensure it’s below 15 amps.
Q: Can a 15-amp breaker handle short bursts of higher current?
A: Breakers are designed for continuous loads; sustained higher currents can trip them.
Q: What if my breaker keeps tripping without overloading?
A: Consult an electrician; it might indicate a faulty breaker or wiring issue.
Q: Can I upgrade a 15-amp breaker to a higher capacity?
A: Consult an electrician; it involves assessing the wiring and load requirements.
Q: Do all devices draw their rated current constantly? ‘
A: No, many devices have varying power consumption, and some draw more during startup.
Q: What happens if I exceed the breaker’s capacity?
A: The breaker trips, cutting power to the circuit to prevent damage or fire.
Q: Can environmental factors affect breaker performance?
A: Yes, extreme temperatures can influence the breaker’s responsiveness.
Q: Are AFCI/GFCI breakers rated differently?
A: Yes, they have specific ratings; consult the breaker’s documentation for details.
