220 volt breaker switch


Ok so i decided to fix my 220 volt dryer outlet because it was hanging off the wall. To be safe I went outside into the breaker box and switched the breaker for the dryer in to the off position. After mounting the outlet back on to the wall, I checked the wiring and everything seemed to be fine. Problem is that when I went to go turn the breaker switch back on, it POPPED and i saw a little jolt of light. I had not even plugged the dryer in yet at the time I turned the switch back on. My question is can a breaker switch blow when switched to the ON position being and nothing is connected to the outlet? Is this a coincidence that the breaker switch was already about to blow? or maybe I have a short which I doubt because my dryer has always worked prior to turning the switch off? any advice will help. I would hate to buy a new breaker switch and blow it too. Also I forgot to mention that after the switch popped the lever feels kinda loose now but Im not taking any chances. I still put it to the off position for time being.

Go back and check the receptacle. You probably created a short rehanging it and the short burned it self open/clear. That is why the breaker is holding now.

How old is the breaker? Dead shorts can cause a lot of damage to one.

Thanks for the fast reply. the breaker switch was replaced about a year ago. I have looked back into the receptacle and I noticed the neutral wire looks like it was loose because of a loose screw and also looks like its not spliced all the way(like only some copper showing through the insulation), not sure it thats normal. Would the breaker have blown if the neutral wire was not making contact?. By the way I only have the 3 prong type dryer connection

A loose connection will cause arcing and heat damage at the receptacle, but it will not cause the breaker to trip.

What do you mean "spliced"?

what i mean is where the green wire makes contact to the center connector. it looks as is the insulation on the tip of the wire was hardly removed which looks like it would make bad contact. like someone used their teeth instead of a wire stripper

If you're dealing with loose wires causing shorts and wires stripped with teeth it's time to call an electrician. Don't risk burning down your house or killing yourself.

Is the wire stranded?

You mentioned that the neutral wire didn't appear to be stripped properly, then you described the condition of the green wire. Green is ground, not neutral. White is neutral. Anyways, having a loose connection will not cause the problem you are describing. You have a dead short. You'll have to pull the receptacle out and look carefully for any signs of arc damage on any of the wires, connections, or the box itself. If it's in a metal box, a wire may have gotten scraped and made contact with the box through the insulation. Do not turn the breaker back on until you identify and solve the problem. I suspect the breaker handle felt loose because it was in the tripped position. Did it still feel loose after you turn it to "off"? If so, you'll need to replace the breaker.

I suspect the white is actually a hot. The OP stated they only have a 3 prong setup.

I wonder how the OP got an insulated ground. MC or conduit?

220 volt breaker switch


Funny, I just dealt with this yesterday. An electrician came over and replaced my old Federal Pacific panel for a new one. Later that night I turned on the dryer and it made a god awful noise. Took the plug apart (3 wire cord) and found the neutral had gotten switched with a leg (so the dryer was getting 120 volts only to the motor and another 120 volts through the neutral and there was no real neutral or ground).

As it turns out, the inside of the switch had a green, black, and white wire. Green and black were the 2 legs and white was the neutral. The electrician had no way of knowing this and had wired the black and white to the breaker and the green to the ground.

Ok it turns out the breaker switch is still good. there is some major issues with the wiring. I had placed the receptacle 2 cm below the original place where it used to be and some how that created a short in the wires. So i relocated it 2 cm above the original spot and I flipped the breaker back on without a trip. I suspect the entire wall needs to come off and the whole harness needs replacing or repair. Not a job for me. Im affraid to go near the whole breaker box itself. Inside the breaker box everything looks half way fried. will call a licensed electrician soon. It is working meantime as before. So much for DIY.

A mounting screw may have pierced the cable. Good call on getting help. You do not want a bad spot left unrepaired in the wall.
