Why does my dw831 grinder keep tripping circuit breakers?

Try checking the brushes. to do this: remove the 2 small covers on the left and right side of the tool and push aside the coil spring holding in the brush. the brush should freely pull out of the holder. when you have the covers off, look for charring or melting. and after the brushes are out, rotate the arbor to move the armature inside and look to make sure it's not charred. if that doesnt help, take apart the handle and look for melted or exposed wire. dewalt likes to pack the wires in tight among the screws and sometimes the normal vibration of the tool will cause a screw to cut into a wire and short the wire. new brushes and holders (if melted) are usually around 20 dollars US

Here is an interesting one. Every now and again we get a momentary loss of power to 3 different lines in our house (all downstairs). Lately the power outage has lasted longer. When I go out to the panel all the breakers are set. Even when I trip them and reset the power stays out. A couple day ago it happened while preparing dinner and my wife says, "Is the oven working. The oven clock was lit so it appeared to be working but when I spun the dial on the oven temp control the power came back to the lines that were down (oven on it's own breaker). Now, whenever we lose the power we turn the dial and get the power back. Three separate circuit breakers are affected by this situation. They are not close to each other on the main panel. More info: Once when the power was out I got a volt meter and checked the power going INTO the breakers. Every breaker was set and power from the street to the breakers was normal. But still out in the house. We did have a ton of rain two weeks ago so maybe there is some residual moisture.

Moisture outside has nothing to do with this. You either have power to the service panel or you don't. There are a few things that can cause these type problems. My first guess would be the problem is right there in the service panel. First turn the main OFF. Then remove the breakers that are being effected, one at a time, and look carefully at the connection on the back where they plug into the main service bar. A loose or burnt connection here will cause exactly what you are experiencing. A breaker that has any indication of it overheating should be replaced. If the main bar is burnt it must be cleaned. If you see any indication that water has entered the service panel then you may very well need to have the service panel replaced if the damage is severe. Another possibility is that you have a junction box somewhere in the attic with some loose wiring. This can be very dangerous as the wiring will overheat from arcing. Move the stove out from the wall and take the stove outlet apart and inspect it to make sure there is no loose wiring in there. As the stove has some effect on this it is highly suspect. I highly recommend you call a licensed electrician to diagnose this problem if you cannot find the problem yourself. This can be a very dangerous situation that may burn your home down. It is simply not worth taking any chances even if you have to spend a few hundred dollars to solve this mystery. Have this fixed ASAP.

Ryobi circular saw --it keeps tripping my breaker

I would inspect the cord before doing anything, checking the leads for signs of scarring which could be due to leakage/incorrect grounding due to damaged internal wiring. The saw could be dangerous to operate so take care and make sure you have continuity after all is said and done that way you don't have to take the saw back apart.

The wire coming from the electronic pack ( blk wire is on the switch with the other blk wire coming threw the switch from power. a red light flashes on the electronic pack when I trip the switch. It will not run or try to run. Is the electronic pack bad??? Do you have an electrical drawing and what do you think is wrong with it. Help. Michael Anderson

How do you change the grinder disk. I have the tool with the two pronges that slide into the nut but the wheel keeps spinning. There must be a trick?

On the top of the grinder there should be a button. hold that in while turning the disk (please have the grinder unplugged while you do this).The button wil drop further in when it finds the notch in the gear. This will lock the spindle, allowing you to remove the retaining nut.

Hey there I do not know how this fix ya site works but I will give it a shot. I am stumped I am working on a nine inch grinder, and here is what it does. Hit the button and it will run for about six seconds then trip a 15 amp breaker. Here is what I checked, the brushes have plenty of life in them, I opened the case unplugged the switch from the motor and I checked it out and is working properly. Moving on to the motor, first I checked for any kind of binding and it is as free and spins well. I went deeper I pulled the entire rotator out of the case and took some emery cloth to it and made the copper armature shine, and cleaned out all the groves, then put it all back together again. I put the brushes back into the case and have 0.9 ohms between the brushes, everything looks well am I just not seeing something that I should....??? Oh yea while I had the brushes out I did check the resistance between the opposing coils on the stater and there is not a short. If for some reason you can think of something that I did not check please let me know. Thanks Tom.

Hello, W/D here.You've checked quite a bit! When you polished the armature contacts, did you polish along the length of the contacts? If not, re-polish in the long direction, and then clean the contact area with electrical cleaner. This may help.--W/D--

FIRST OF ALL !! Control where the tool is used first for undervoltage on the mains supply group. If it is everywhere a problem FIRST replace the circuit breaker.
