Trying to save money, I purchased a used stove for $50. The man I bought it from said it worked. It has a digital clock, but doesn't have a glass top. It came with a 3-prong plug. We replaced it with a 4-prong and now it arcs a bit and flips the breaker when we plug it in. It had a copper strap that came from the ground screw and bolted to another screw about 2 inches below. We removed the copper strap (info from another web site) and attached the 2nd ground wire from the new plug to that lower screw. What are we doing wrong??:confused:

This may help http://www.applianceaid.com/electric.htmlNote that you do not have a second ground you have Neutral and ground but if you switched them it should not cause a breaker to flip. Double check the wiring at the units terminal block. Does sound like you have it hooked up correctly. You said it arcs, where? Remove the terminal block from the unit and check it. Make sure all elements etc. are set to off. I would use a meter to check for resistance at the plug, sound like you have a dead short (0 ohms) either L1 to Neutral or L2 to Neutral. I would use this to find the short, there is a good chance that the arcing is going to blow your control board if it has not already done so. |

If your terminal block goes left to right, or up and down, this is how you wire it. Red goes to one end, white goes to the middle, and black goes to the other end, and the green wire could actually be taped off, if you do not have a ground screw. If the oven flips the breaker after that, you need to look for a wire that possibly came off somewhere, during the move. Tom ApplianceEducator.com

I would not recommend taping off the earth ground wire (green)
This would defeat the reason that the 4 wire hook up is used.
It is used so that if for any reason you loose Neutral and a line in (L1 or L2) should short to the frame of your unit, the case is now live. Touch the stove and lets say a tap which is usually grounded through the copper plumbing and ZAP.
You could reattach the ground strap and then not connect the earth ground but this will put you in violation of the electrical code. If you should happen to have a fire here and the insurance company finds this, they could try and use it as an excuse to not pay even if it in reality it has nothing to do with the cause of the fire. There are some pretty slippery insurance companies out there. |

Denman, some dryers do not have a spot for the earth ground. As I quote myself. "If you don't have one". We have only got along with the 3 wires plug for 50 years, its no big deal. It is kind of like, the flex dryer vent hose. It also has worked for 50 years, but now it is unsafe, and will burn your house down. The only dryers that I have seen that will burn a house down is when people buy a used dryer, and some repair shop, jumps out the saftey thermostat. I have witness that on numerous occasions. By the way, as far as electrical codes, in the United States, codes vary from place to place, and rural areas like where I live, don't have much codes. Tom ApplianceEducator.com

The original post says he has a ground strap bolt, he used this to attach the earth ground wire from his 4 wire line cord.
I would rather lean towards caution when it comes to electrical code.
May be too cautious but I would rather be safe than sorry. |
