This breaker is only a few months old and stopped working recently. Power is getting to the motor but it doesn't hammer - There are electrical flashes from the motor housing when attempting to use the device but nothing else, no vibration whatsoever. Is this a problem with the motor brushes (hence the arcing) or something more serious i.e. the main piston. I spoke to NuTool and they think the brushes are ok. Unfortunately they don''t have a technical data sheet available for a few weeks, so I don't want to risk just taking the thing apart just yet. Any help appreciated.
I have a Rockworth Powertask which appears to have the same problem when exposing the drive gears the spline drive gear had been completely shredded together with a ball bearing race the driver gear was intact & the secondary drive gear would appear to have destroyed the drive gear - suggest repair

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.
Hi Sammy, It sounds like there is a direct short on the circuit. Before going any further, check other outlets on this circuit and make sure they do not have anything plugged in that is not expected and does not work. Check OUTSIDE your home, basement, garage, etc. as these locations require GFI protection - and may be fed from the bathroom outlet. After removing devices that are plugged into the circuit, attempt a reset of the breaker once more. It is not likely that the circuit breaker has failed (but is a possibility). The outlet in the bathroom is probably a GFI type. You can determine this if it has "Test" and "Reset" buttons on it. You should be able to press the Reset button in fully even with power off. After resetting, you can attempt the resetting the circuit breaker as you have described above. If it stays on, try pressing the "Test" button on the outlet. Doing so should trip power to the outlet (and causing the "Reset" button to pop out) but leave the circuit breaker "On". If the breaker also trips, the GFI outlet is suspect and might need to be replaced. At this point, a qualified electrician should be consulted to locate and clear the wiring fault.
A 30 amp circuit breaker or fuse is NOT a typical size used for the protection of convenience outlets & general lighting circuits, especially in a residential setting. In fact the National Electrical Code (NEC) prohibits anything larger than a 20 amp breaker to protect a #12 copper wire and and a 15 amp breaker to protect a #14 copper wire. These are the size wires used to supply nearly all outlet and lighting loads in a residence.
It's not clear to me from your question if this 30 amp breaker is a double pole type that is providing power to a second, smaller circuit breaker panel and these outlets are fed from it. This would be in line with what the NEC would allow and what I suspect is the situation. I'm only going to get into this a minimal amount as more information is needed for me to be able talk intelligently about it.
I would shut off the loads that are connected to the 30 amp breaker. If that is a panel, I would shut off all the circuit breakers in it, then turn onn the 30 amp breaker. If it trips, then there is a problem between the 30 amp breaker and the panel. You may have connected line cables to ground or neutral - and vice-versa.
Can you please explain in as much detail as possible what is connected to the 30 amp breaker? Is it a single pole (120 volts) or double pole (240 volts) circuit? What size wires are connect to the breaker terminal(s) What type of cable is connected to it? How many wires are in the cable assembly or pipes? What is the size of wires? If they feeds a second, smaller breaker panel, where do the wires terminate - into lugs on the top or bottom of the panel or terminals of a circuit breaker? What happened or changed to cause this circuit breaker to start tripping? Is this part of a new installation - and if so, was the wiring done by an electrician? Was the work inspected?
Please try to answer as many questions as possible. The more information you can provide will help me get you the best answer.
the motor will have same colors most likly black , yo wiil need the right breaker it will have three lugs on it just run three of the same gauge to the motor and crimp the wires make sure you get the right breaker to wire 20amp 12ga 30amp 10ga good luck
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.
The first thing is to turn off the main breaker. Wear safety glasses! This will kill the power to the panle except to the main incoming lugs. If you cannot shut off the main then call an electricianIf you have a square d panel then it is a QO breaker. Simply pull out the defective breaker by pulling straight out. Look at how the fingers grip around the silver bus(where you get the power from) and the plastic bar (it holds the bottom off the breaker)<
ok start at the pannel is there a double breaker there
usually a 30 amp two pole breaker this is how a pannel works first breaker pulls 120 off of one side of pannel second breaker pulls off 120 off the other side of pannel if you look the buss bars you will see that they interchange from one side of the pannel to the other so at the breaker you are checking make sure you have 120 v on output of one half of breaker and 120 on second half of breaker when you use a volt meter put one side to gng the other side to wire comming out of breaker you should have 120 on both sides if not you have a bad or tripped breaker
