![]() The ground wire connects to the case of the electrical device and should never have current passing through it.Ī little history on the whole 3 vs 4 wire plugs. The ground wire has absolutely nothing to do with the load. White carries the unbalanced load between red and black (10A on black and 5A on red would mean 5A go from black to white). Red and black are your live wires and carry the bulk of the current. Both devices are grounded, but bonding the two together allows circulating current, and that circulating current passes through you. In my parents house, you will feel a very mild tingling in your fingers if you touch the door of the refrigerator and touch the oven at the same time. Leaving the device ungrounded just means you could potentially get a 120V shock if you touched the case of the ungrounded dryer then touched something that is grounded like a refrigerator or a water pipe. It's only there to protect you against shocks. The grounding has nothing to do with the actual operation of the device. The dryer should still work even when it's not grounded at all. Unplug the dryer then use a multimeter to check resistance between the neutral and ground connections of the dryer plug. You can easily test if your dryer's wiring internally connects the neutral and ground together. This is also why devices are not allowed to have multiple ground points. This is why the electrical code states that wires connected in parallel must be exactly the same size and length of wire. That's an effect seen when two or more wires are tied together at multiple points but the wires are different lengths or different sizes. If neutral and ground are also tied together at the receptacle, this creates a closed loop that would allow "circulating current" to happen. Since this thread has been revived, I moved it from OT.Ĭlick to expand.The only thing I can think of that would cause this is if the wiring inside the dryer tied the neutral and ground together. Which leads me to believe that they wired their dryer cable wrong and fixed it by messing with the 220v dryer wiring instead. The WTF thing is that the previous resident's dryer worked. I feel like I'm lucky this place didn't burn down. He wired everything up right and, miraculously, my dryer still works. ![]() They had it hooked up wrong at the breaker. Not only that, but the wiring was used incorrectly (the exposed ground wire was live!!!!). The wrong voltages were going to the wrong pins on the outlet. After looking at the outlet and the breaker, he determined the whole thing was just wired totally wrong. He wasn't authorized to go past the outlet, so I called an electrician. The LG guy probed the dryer outlet with a multimeter and told me I had bad voltages on the outlet. ![]() So I called LG and they sent a technician out to look at the dryer. I assume something is wrong with the dryer because I had seen the previous resident's dryer running when I checked out the house. The outlet sparked and started smoking so they removed the cable. The installers wired up a cable and plugged it in. I moved into a house a few weeks ago and my new washer/dryer showed up a few days ago. ![]()
