The 3 types of circuit breakers
They’re all in the Box
You’re likely to see switches for three different types of circuit breakers in a panel-single pole, double pole and ‘tandem.’ Single-pole breakers feed 120-volt circuits for ceiling lights and most wall outlets, while double-pole breakers feed 240-volt circuits for appliances like electric ranges and central air conditioning systems.
Tandem breakers also have two switches. They take a single slot inside the circuit breaker panel and turn it into two 120-volt circuits to save space. Learn to fix a tripping circuit breaker.
Step 4
What to do if your circuit breaker won’t reset
This first thing to do is to make sure you don’t have too many devices plugged into the same circuit. In order to determine if that’s the cause, unplug everything running on that circuit and reset the breaker. If the breaker stays on, start plugging things back in one item at a time until you find the problem. Then, if possible, you can plug a device that’s overloading the circuit into another outlet.
There are other causes for a breaker that won’t reset. And in those cases, you’ll need to call a professional, licensed electrician. It could be a short circuit or a bad breaker, both larger problems that you’ll definitely want a pro to handle.
FAQ
Can a circuit breaker reset itself?
No, they don’t typically reset themselves. Once a circuit breaker trips, it needs to be manually reset by toggling it back to the “on” position. If a circuit breaker seems to reset itself without manual intervention, it’s not functioning correctly, and you should have it inspected and replaced by a qualified electrician. Operating a malfunctioning circuit breaker can be hazardous, so it’s essential to ensure they’re working as intended to maintain a safe electrical system in your home.
Why won’t my circuit breaker reset?
When your circuit breaker won’t reset, it can be a sign of an underlying electrical issue that needs attention. There are several potential reasons for this problem. It could be due to a persistent electrical overload, a short circuit, a ground fault, or even a faulty circuit breaker. To address this, start by unplugging or turning off devices on the affected circuit to reduce the load. Then, firmly push the breaker switch to the off position and then back to the on position. If it continues to trip or won’t reset, it’s crucial to consult a qualified electrician to diagnose and fix the problem. Attempting to reset a circuit breaker repeatedly without addressing the root cause can lead to electrical hazards and should be avoided.
How long can you leave a circuit breaker off?
Leaving a circuit breaker off temporarily is generally safe and, at times, necessary during electrical work or in case of a tripped circuit. However, it’s essential to minimize the duration to avoid inconveniences. If it’s a circuit that powers essential appliances or equipment, you’ll want to restore power as soon as possible. On the other hand, if the circuit remains off for an extended period, it can lead to issues like spoiled food in a refrigerator or freezer, or a non-functioning security system. For this reason, it’s advisable to leave a circuit breaker off only for as long as needed and to address the underlying problem promptly if it’s a tripped circuit.
