Safety First!

1) Remove all load devices from the breaker circuit (unplug everything).

2) Reset breaker and observe. No problem, move to step three.

3) Add back one load device at the time.

If it's winter, and the device that reproduces the problem happens to be a space heater, stop here, you solved the problem. Move the space heater to a less populated circuit.

4) If you add your I-Pod charger and the breaker trips, you could still need an licensed professional to investigate.

In my experience (almost 39 years) doing electrical work, circuit overload is the most common cause.

Before you consider the breaker broken make sure that it has not just tripped. Push the handle of the suspected breaker all the way over to the off position. If there was a bit of resistance when turning to the off position before going to the completely off position this is the breaker re setting. Now move the breaker handle to the on position. If you have the ability to check the voltage or the circuit restores voltage to receptacles that were without voltage then the breaker is good. If the breaker has no output voltage at all after following the above instructions, replace the breaker.

How to tell if 1964 240 V stove plug is tripping the circuit breaker or is the circuit breaker bad?

You may need to call in an electrician, or appliance repairman.See view discussion below.


How do you tell if a wire is shorted out?

If by meaning wire as a circuit, when turning on the circuit the fuse will blow the circuit open, or if the protection is a breaker, the breaker will trip. This is all on the conjecture that there is a return path for the current to flow. This is the main reason for ground wires on all equipment, to provide a return path for the current to flow back to the source.


What Voltage type are in outlets at home?

Your home electrical wall outlets current capacity is governed by the breaker that feeds that circuit. In most home situations the wall receptacles are fed with a 15 amp breaker. Dedicated outlets could have a higher ampacity as they are installed for specific appliances or devices. To check your circuit, plug a lamp into the outlet. Start flipping the breakers off. When the lamp goes out that is the breaker for that circuit. Look on the handle of the breaker and it will tell you the capacity of that particular circuit.


What can cause a circuit breaker to suddenly start tripping?

If the breaker trips when nothing is turned on it could be a mouse problem. If it only trips when certain lights or appliances are turned on one of them is probably the reason.If it trips when nothing is being turned on or off something is getting hot. You should then have qualified electrician look at it. Hope this is usefull.


How do you tell if someone is stealing your electricity?

Turn off your main circuit breaker (so that all of your power is off) then look at your meter. If the meter gauge is still spinning, it means electricity is being used somewhere between your meter and your breaker (BIG NO NO!!) And a sure sign that someone is stealing your electricity.

If you have a 93 f150 can you tell me if the wiper fuse is a reg fuse or a circuit breaker and if its a circuit breaker whats the parts number on it?

its a circuit breaker... call the dealer for the parts # or just buy it from them ($40). Try a junk yard or craigslist f150 f250 and bronco about the same year are all the same i think.


Reset electric window breaker on 1985 325e?

Resetting Auto Circuit BreakersWithout doing a "hands on" troubleshooting of your vehicle no one on this site can tell you specifically, what is causing the problem, or where to find it. It has been my experience that all of the circuit breakers for automotive applications are self resetting.Inside, they use bimetallic strips, and reset themselves when the circuit current overload, or short circuit conditions, has been removed/eliminated, and the bimetallic strip has cooled down.IF your breaker is not resetting itself after a reasonable "cool down" period, then that suggests:A short circuit condition somewhere in that circuit, orAn overload condition due to the addition of too much "extra" electrical equipment [like for example, a "monster" audio amplifier, or a light bar set], orReplacement of an electrical device with one which uses much more current than the replaced device, orA defective circuit breaker.

What causes circuit breaker to trip even when it's properly rated?

A circuit breaker is dual function. The only time it will trip is if it senses a fault current that is rated higher than the breaker rating (short circuit). The other trip condition is if the circuit is overloaded and is drawing a current higher than the breaker rating. On breakers that protect motor feeders the breaker has to be rated 250% higher than the motors full load amperage. If the breaker has lots of use and is used for a switch being manually turned off and on will weaken the trip value of the breaker. If you have access to, or know an electrician, a clamp on amp meter on the conductor that the breaker feeds will tell you what is happening. Clamp the line and turn on the load to see exactly what the current is. If, like you say, the breaker is properly rated and the current is within the breaker limits then change out the breaker for a new one.

What would cause a breaker to trip?

A breaker will keep tripping until the fault that caused it to trip is corrected. That's what it is designed to do. There's either a circuit overload or a short circuit. How fast the breaker trips can indicate how overloaded it is. If you are very close to the rating of the breaker you can actually trip it over time. If you are definitely over the breaker will usually trip instantly. If there is a short circuit you can usually tell that by how violently the breaker trips. If you have conduit you can hear the wires banging around in the pipe. A frequently tripping breaker may also be faulty and need to be replaced - breakers are designed to fail by tripping prematurely rather than by not tripping at all, as this is much safer. This is very often the case for breakers that trip at seemingly random intervals, often when very little load is being drawn.


How can I tell if a fuse or circuit breaker is blown in 97 trans sport?

Circuit breakers are difficult as there is not an otside way to tell if they are bad. The plastic blade type fuses are easy pull out the offending one and look through the plastic at the top to see if the wire is broke or not. If it has a space in the wire the fuse is bad.
