I Have a Buzzing Noise in the Breaker Box When - Hunker
One problem that could cause a buzzing sound in your breaker box, when the A/C is on, is a loose wire connection. If the wire is not attached to the breaker securely or if there is a loose connection or damaged wire somewhere between the breaker and the power source or the air conditioning unit, it could buzz and fizzle and potentially even spark.
Why Does My Circuit Breaker Panel Make a Buzzing/Humming
.'s only heard as the AC starts up. If the buzzing noise occurs right as the AC kicks on but stops once your air conditioner is running steadily, this is normal. You see, large motors (like the one that runs your AC) draw a LOT more energy at startup than it does when it's steadily running.

Circuit breaker buzzes when AC comes on? | Yahoo Answers
Jul 30, 2011We got a new 200 amp service. We have a 50 amp breaker on the panel for the Furnace and ac. When the ac comes on, it makes a quick buzz sound. We have changed out 3 times the 50 amp breaker and we moved it's position. It still buzzes. We had a 30 amp before and don't know if it buzzed because it was in the basement and no one ever went down there.Followers: 1Status: OpenIt is actually normal for some breakers to hum or buzz when a large load is initially applied. In your case, the AC unit is likely drawing close to maximum amperage for the circuit on startup. After the unit starts, the amperage decreases and the buzzing goes away. This is normal for any large motor. Only if the buzzing becomes continuous should you be concerned.Best answer · 2Hi There, When the compressor starts up there is a large "inrush current" until the motor comes up to speed. This only lasts for a very short time (about half of a second or so). this inrush current (called locked rotor current or starting current) can be 2 to 3 times the full load current. Another thing is that when the compressor starts is under more than full load because the suction pressure is much higher than normal until the compressor starts pumping. Then the suction pressure becomes normal for the temperature. No doubt the buzzing noise is during the start up of the compressor when pressures are high and the motor on the compressor is not up to speed. Since you have changed breakers I would not expect the circuit breaker itself to be faulty. Also you have tightened all the screws so a loose connection can be "rued out". Some circuit breakers have small coils inside that energise to provide an "instantaneous trip" in case of a short circuit. Some of them have a "time" feature built-in to allow overcurrent for a given time frame. This allows for the inrush current while a large motor is starting. If that is the case the buzzing may simply be the sound caused by the coil being energised at the higher than normal current. Another thing to consider and check is whenever current flows through a wire it creates a magnetic field causing the wire to move and sometimes "jump around". This movement can cause a buzzing sound. If it were my system I would check the manual for the recommended circuit breaker size to make sure 50 amps is sufficient. Also the wire should be a minimum of AWG 6 wire at a max of 33 feet. Probably your compressor is farther than 33 feet away so I would use AWG 4 copper wire. Your electrician can check the wire size ( and probably already has sized the wire properly) The only other thing I can 'see' that could cause the buzz would be that the "stabs" that connect the circuit breaker to the Buss may be a little lose (or the buss rails inside may be worn a little) which could cause the breaker to be a little loose. If that is the case the breaker could cause the buzz during start-up. If everything checks out then personally I would not worry about the buzz. To be sure you can call the manufacturer of your breaker box and ask their advice. Hope this gives you some information and haelp, Al2Breaker Box Buzzing0This Site Might Help You.

We have changed out 3 times the 50 amp breaker and we moved it's position. It still buzzes. We had a 30 amp before and don't know if it buzzed..0Your breaker for the furnace is for the furnace. Your A/C is on a separate breaker, and it uses the furnace to move air across the coil that most likely sits on top of your furnace. Without a furnace, it would be called an Air Handler. It would have your coil in the same box as the blower and would still be on seperate breakers. But your outdoor unit is the actual A/C, and that will be a different breaker. That being said, make sure you are hearing the correct breaker buzzing. Try setting your thermostat to off, and your fan to on if possible, otherwise, set it to heat and turn it on. If it doesn't buzz, then it is the other breaker that is buzzing, and it may be buzzing due to high amp draw from the compressor at start up, or that breaker could be faulty. If it buzzes again, then you are looking at the right breaker and I have no idea what is wrong. Possibly some crappy wiring. Maybe both your A/C and Furnace are wired into the same breaker. In that case, have an electrician wire it correctly before you burn your house down.0Circuit breakers will trip at lower amps than rated as they get older or go through s condition where it has been tripped repeatedly over time. The buzzing is usually a breaker on cusp of tripping because the amperage is right at cutoff, REPLACE breaker! Another giveaway that breaker is going bad is that it will get hot. Why is my Circuit Breaker Box Humming? A loud buzzing or humming sound coming from a circuit breaker should raise a red flag and requires inspection. Some likely causes of loud humming noises in the breaker box are: A breaker that is carrying a significant load but is failing to “trip” or shut off may make a loud sound and should be repaired or replaced in order to prevent an overheated circuit. Sparking or a fizzling may be the result of a connection problem. If this is the case then the wire needs to be tightened or the entire circuit breaker could need replaced. A circuit breaker that makes a humming noise as soon as it is turned on then quickly shuts off is typically the result of a circuit problem. Circuit breaker problems like this stem from the electrical circuit itself, so the circuit breaker may not have to be replaced. The individual circuit might just need to be repaired. Anything unusual like a loud noise, mysterious humming in the breaker box or heat radiation and sparking around the circuit breaker panel is not common. If these types of situations occur, an electrical inspection should be done.0are you certain that no dryer hook ups or anything else is on the same circut ? if i am correct there may be a problem with the wiring itself - what wiring was used and what gauge ? check the breaker itself next time it buzzes and see if it is slightly warm to the touch - it sounds to me that there is a shorting problem somewhere or too big a load to begin with for some unseen or unknown reason - if the ac unit is an older model unit or has many hours on it - then there may be a short in the unit itself on the start up procedure part - i am talking exterior airconditioners that are outside units that sit on a concrete pad - in florida there are many - what happens is they ice up a few times - overide shut down kicks in but doesant restart right from overload switch - so i would have the unit checked because even though it still runs - there is overload for some reason from the unit itself probably - its a 90 percent chance of a part failure in the airconditioner - or condenser - sincer - or low frion in the unit could very well be the cause to - to low of gas charge in the compressor will run really hot - and that pertains to over load too even when cooling a little - so i would triple check unit first at this point1There's no reason for the breaker to buzz, it could be something loose in the breaker box. Try tightening all the unused screws in the grounding bars. Sometimes a near capacity load can cause a vibration in the wiring, which could also cause a vibration in your panel. I'm assuming that this buzz is only on startup of the unit.0Call a competent HVAC tech and have him install a hard start kit for the compressor. That will remove the buzz.1
electrical - One of my breaker switches buzzes when I flip
One of my breaker switches buzzes when I flip it on, should I replace it? Ask Question Fortunately I still had the box so I returned it and bought a better brand and it seems to be working a lot better & got rid of the low level hum that was barely noticeable but always there when the previous breaker was supplying power. – virtualxtc

what causes the humming noise thats coming from my fuse
Feb 04, 2011Answers. A more definitive test is to turn off all the breakers. If the hum continues then the problem is in the backplane of the fuse box, maybe a loose bus bar. If the hum stops, then turn on the breakers one at a time until it starts again. Whatever is connected to that breaker, or the breaker itself, is the culprit.Status: OpenIf the hum continues even with each breaker off one at a time, it could be something being fed by two breakers or a breaker being backfed by another circuit.

The humming noise that you are hearing is coming from an arching of electricity between the contacts of the breaker, and the bus bar that it is attached to. Switching breakers as far as replacing the one that is making the noise might fix the problem. You might be able to do this yourself if you are a handy kind of person. You would need to disconnect the power source and simply unscrew the circuit wire that is landed on the set screw. Simply pull the breaker out and snap in the new one, reversing the part described earlier. Parts of this nature do occasionally wear. It is something that you should take immediate care of however. Please let me know if you think you have any further questions.0Rv Fuse Panel0put your finger on the breakers one at a time , if one is very hot it may need replacement or something on that circuit is drawing too much. be careful some of that stuff bites2Watch yourself hot breakers can explode.0Wait QPR have beaten two teams in one season.0For the best answers, search on this site https://shorturl/avxUY PMSL !!

Causes of Electric Circuit Buzz or Crackle
Electrical Panel Noise A short within an electrical circuit could cause a buzz or hum sound at the electric panel right before a fuse blows or a circuit breaker trips off. The affected circuit should be identified so the circuit load may be identified and evaluated so the necessary repairs may be performed.
