The Lights circuit breaker keeps trips without load

The Lights circuit breaker keeps trips without any load. Overnight the circuit trips. The circuit works OK for a while but either during the night when the lights are on or overnight when all lights are off it trips.

Circuit Breaker Keeps Tripping


Your circuit breaker keeps tripping and you are wondering why it would do that. There actually can be many things that can cause a circuit breaker to trip, or shut off. I will give you some reasons why circuit breakers trip and also some circuit breaker troubleshooting tips.

The first thing to remember about a circuit breaker is that they are first and foremost a safety device. The protection provided by the circuit breaker is also two fold. The circuit breaker will protect against overcurrent, or in other words, it will keep you from melting down the wires by placing too high of a load on any circuit. This would cause the wires to overheat and start a fire.

The other way a circuit breaker protects you is that the circuit breaker senses very quickly if there is current flowing to the ground with out it going through a load. This means that there is a shock hazard or a fire hazard. The circuit breaker will interrupt the current and shut off to prevent damage from happening.

If your circuit breaker is tripping off then you need to find out why this is happening. By eliminating the load on the circuit you can start to narrow down the possibilities. If there are a number of things plugged into the circuit then unplug something till it will stay on.If you can get the load low enough so that the circuit breaker stays on then you are okay and just need to spread the load out over a couple of circuits to prevent the overloading.

If you cannot stop the circuit breaker from tripping, unplug loads until you narrow the problem down to one thing. Once you narrow it down to one thing that is tripping the circuit breaker then you can find out why the load is tripping the circuit breaker.

Now if the load that is still plugged in is an appliance like a washing machine, then you need to find out if the cause of the tripping is the motor or if it is something like a wire that is rubbed through and is shorting out. If it is the motor the circuit breaker will often trip right when the motor goes to start up.

If the circuit breaker trips immediately when power is applied then you probably have a bad wire or connection. Poor connections are common in appliances such as an oven or a dryer where high amounts of current can be pulled at one time and the heat will make the connection get hot and eventually fail.

There are so many different possibilities for circuit breakers tripping that it is impossible to cover them all. There is one tool that will make the detective work of finding a short or problem much easier.This tool is called an "OHM" meter. One of these can be purchased at most any hardware or electrical store. Many big box stores and even a Wal-Mart also have them. There are many very inexpensive models available.

By using an OHM meter you can check the resistance of a circuit. The idea is that if a circuit has NO resistance to ground then it is bad and the electric can flow to the ground unhindered. This is a dangerous situation and must be corrected. In motors the flow of current between phases with no resistance, is also a reason why a circuit breaker will trip.

Above all remember that you need to verify and make sure that all electric is shut off to any piece of equipment that you are working on. Isolating and finding electrical problems can be very time consuming and frustrating. It will take time and patience to methodically eliminate the possible causes of a circuit breaker that keeps on tripping or a circuit breaker that will not reset. Through careful checking you can one by one eliminate the possibilities and find the cause of your circuit breaker not staying on.

Holmes hch6150 will not produce heat


Without having the heater to tear apart to see what is not working, you may try the following. Your heater is a 1500 watt heater and pulls about 13 amps of current. If you plug it into a recepticle that is already have load turned on, most recepticle circuits are rated for 15 amps and you have probably tripped the breaker for this circuit. Check your breaker panel to see if a breaker is tripped. If it has tripped, this will tell you your pulling to much current. Try another circuit that allows the heater to operate or find the other load on the circuit that is causing the breaker to trip. By the way to reset the breaker take the breaker to full off, this resets the trip, and then turn it back to on.
Hope this helps

My lights dim and microwave fan slows when turning on toaster


ABSOLUTE FIRE DANGER
Do NOT keep overloading circuit until electric is brought up to code.

Voltage drop.
Your breaker is rated more amps than the wire ... so wire is getting hot ... and appliances are starved for power.
The breaker should trip, but somebody has put in larger breaker without installing larger wire.
So wire is getting hot as appliances draw more power than wire can safely carry ... but the breaker should trip when wire gets hot ... but breaker is not tripping because it is oversized.

Microwave should be on dedicated 20 amp circuit ... which means 1 breaker supplies voltage to microwave and nothing else. This is code today.

No lights upstaires circuit breaker keeps tripping


Jan 2013
1) Move wire to another same-size circuit breaker to eliminate bad circuit breaker as suspect.
Do NOT increase size of breaker or it will cause fire.
http://waterheatertimer.org/How-to-replace-circuit-breaker.html
http://waterheatertimer.org/Troubleshoot-household-electricity.html

2) Put hand on each appliance and outlet to see which ones are warm. Outlet should never be warm or hot. Replace outlet. Inspect wires for loose and burned connections.

3) If the breaker is good, then add up total watts being used by checking watt rating on each device. 100 watt light bulb is 100 watts. Big screen TV has a label that shows 300 to 500 watts. Computer has label. Space heater has label showing 1500 watts. Iron has a watt rating label. Take total watts and divide by 110Volts and this will give amp load. Total watts used = 2000 and then divide 2000 by 110 volts = 18.8 amps
Compare amp load with circuit breaker.
20 amp circuit breaker has 80% safe maximum, or 16 amps.
If amp load is 18.8 amps, then 20 amp breaker is starting to get hot, and weak breaker will start tripping.
If amp load is 18.8 amps, and breaker is 15 amps, then you are overloaded and breaker is feeling the heat, and tripping because of heat.
Solution is to reduce amp load.

4) If you have short circuit, that can also trip breaker.
Unplug everything and then plug things back in slowly to see which plug or appliance is causing the problem.

Siemens breaker just for overhead lights in bathroom and hallway Why does it buzz for a second then TRIP off?


You say the breaker supplies power to just one or two lights? And no outlets, fans, attic circuit? Map out all affected electrical boxes.
Move wire from suspect breaker to another same-size breaker and see what happens.
Move wire from the other breaker a to newly installed breaker, to check if breaker is main suspect.

Open each switch and outlet box affected by suspect breaker.
Disconnect power at light switch, and see if breaker still has problem.
Unplug all things from outlets on circuit.
One by one, check each electrical box for burned wires and loose wires.
Use nose to smell for burned condition.

Add a comment and update as you progress through troubleshoot.

Breaker installed on generator. Keeps tripping under no load after approx. 1 minute of generator running


A tripping circuit breaker is an indication of an overload. You say there is no load on the breaker - how are you making this determination? Are you using an amprobe or some other meter?

A circuit breaker with NO load shouldn't ever trip. Likewise a circuit breaker carrying up to 80% of of the current it is rated for shouldn't trip either. Circuit breakers that carry more than 80% of their load will trip - if the load remains connected long enough. This is called "duty factor" or "service factor" The greater the load is in excess of 80%, the less time that the breaker will carry it before tripping.

An example of a 100 amp breaker with different loads on it (this 100 amp value was chosen for ease of doing the math):

80 amps - never trips
85 amps - trips after 48 hours
90 amps - trips after 16 hours
95 amps - trips after 8 hours
100 amps - trips after 4 hours
105 amps - trips after a few minutes
120 amps - trips after a few seconds
150 amps - trips instantly

This is only an example to show how a certain circuit breaker might trip under a load less than the rating stamped on the body or handle.

A circuit breaker that trips with no load or a load equal to or less than 80% of its rating is most likely defective. You need an amprobe or ammeter for amp readings. If the load is found to be 80% or less, there may be an issue of harmonics that is causing the tripping. You'll need to have special equipment and qualified persons to check harmonic problems. Most harmonic problems occur when the loads are not linear device (transformers). Examples of non-linear devices are "switching" (or solid state) power supplies like those in computers.

I hope this helps and good luck. Please rate my reply. Thank you.

Eaton Arc Fault Breaker type BRAF tripped. I reset it but lights will not work. Ideas please?


My arc fault breaker trips in my bedroom when ever a load is put on line. The trunk line comes into a three gang switch box and feeds the entire room. At times I can turn my ceiling fan and light on for 10 to 20 minutes before the breaker trips. Other times the breaker will trip when either switch is first turned on. I plugged a 4 watt night light in a wall receptical, without the ceiling light or fan on, it also trips the breaker. I have had other plug in lamps, 60 watt, work in other recepticals for a while. The problem seems to appear in all recepticals and lighting in the room.

Circuit breaker trips out when all lights on the circuit are off.


Hi,
You have a dangerous situation there. If the breaker is tripping like that and espec. if you have no load on it then there is an intermittent short that is happening in the circuit somewhere. The hot wire is shoeting to the neutral or ground wires at some time... This will cause a fire if you leave it and do not find the cause. The best fix would be to rewire the whole circuit if you can not find the cause of the short. To identify the short look for a black spot in the wiring some wher. the arc from the short will cause a burn mark when it happens..
Good luck and be careful!!

Timer doesn't come on after being set. Operates landscape lights


Check your circuit breaker that feeds the timer circuit in your main electric panel. It may have tripped. Sometimes when a breaker trips it's hard to tell visually, so turn the breaker off, then back on.
Also, the circuit that feeds the timer may be on the load side of a GFCI receptacle. Look for one that has tripped. Sometimes they are found in obscure places.
