Loose wire in panel box or loose wire around compressor. any loose wire causes a high amp draw which blows the breaker. I've found wires that look good but are loose. Go right to the compressor outside and check there first. pull disconnect first and make sure there is no power. you either have a shorted compressor or loose wire. if you ohm out compressor with power off and disconnect the three wires you will get something like this....one wire to other wire 2 ohms... same wire to other wire 3 ohms... other two wires you should get 5 ohms...2+3=5 good compressor.they will add up to each other.

If the breaker itself is more than 15 years old, replace it. If it continues to switch off, check the amp draw of both the inside and outside unit.

Your compressor is trying to restart after it shuts off which is causing a power draw down changing the sound of the fan speed change. Check voltage power supply and insure that the power supply cord is heavy enough to carry the necessary load.

SOURCE: a/c is drawing 20 amps and keeps tripping breaker after running

If the fan is running and the compressor is getting hot and tripping off you may have a failed capacitor.

Breaker is to small , if the full load amps of the unit is 95 amps , to correctly size the breaker to code multiply the full load amps by 175% minimum and 225% maximum. A 200 amp breaker is the size breaker that I would recomend for this application.

SOURCE: I have 60 amp circuit breaker on my electrical a/c

You're unit is a 31/2 ton according to the numbers.Normally, breakers will only be in a half way posistion when tripped. Yes, under most conditions, the fuse will blow before the breaker trips. I have seen this many times, the breaker may be weak, burned, loose wires and so tighten wires, check the condition of the breaker.It sounds like the breaker even though it is 60 amps, is the problem and you should replace it with out hesitating. This will solve you're problem. When you pull the breaker out, look at the metal clips that snap in on the buss bar to see if they have been overheating.And the buss bar its self. You will know. I am sure this will take care of you're problem. Good Luck,

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.

Breaker trips when heat on wire exceeds amp rating, or when breaker is bad.
Most breaker are slow acting, and do not trip immediately.
Shorted elect could cause problem.

15 AMP breaker keeps tripping


do a amp check on the compressor and fans.That will tell you exactly what is overloading.

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.

Why is my 50 amp GFIC breaker tripping out? I have just installed a new hot tube.I had one there before(smaller 40 amp) so there was already #8 wire there.The new hot tub requires a 50 amp. #6 wire. I just...


There might be a few things here:

1) Big problem >> the #8 wire is a fire hazard connected to a 50Amp breaker

#8 is a 40 amp breaker
#6 is a 55 amp breaker
We put #6 on a 60 amp breaker
Are you saying you hooked the #8 wire to the new 50 amp breaker, and the hot tub called for #6 wire?

Upsize your wire and breaker to meet code
http://waterheatertimer.org/pdf/Wire-size-amp-rating.pdf

2) After putting the correct wire and breaker, you can still have a short in the circuit somewhere
We used to set equipment out in the field in early morning >> the grass was wet >> our equipment was fine, but the tiniest short would cause the GFCI to trip

I don't know where the problem is without a thorough checkout of every possible grounded surface. You need a good multi-meter

3) You better get an electrician over there to have a look before the place burns down or somebody wakes up dead in the hot water.

If I sound a bit scary here, it's because something doesn't sound right with your installation.
