If there are only two prongs, then ground wire may not be utilized. If your outlets have three prongs, then your home has ground wire. To tell if your home has ground wire, check your outlets. Although it is a requirement by the NEC for newly-built homes, older homes don’t always have a ground wire. Ground wire is easily identified by its green casing. But when an electrical accident such as a short circuit occurs, the ground wire takes the unstable current away from your electrical system and sends it toward the ground. Under normal circuit conditions, ground wire isn’t carrying any current. So, with hot and neutral already being used to make a circuit, what role is left? The answer is safety of course! Ground wire acts as defense against unstable electrical currents. Although they may not always be circulating an electrical current, they should be handled with as much caution as hot wire. Neutral wires are identified by their white or gray casing. Additionally, this prevents faulty or excess currents from residing in your outlet. This gives currents circulation through your electrical system, which allows electricity to be fully utilized. More specifically, neutral wire brings the circuit to a ground or busbar usually connected at the electrical panel. Neutral wire carries the circuit back to the original power source. Once hot wire has initialized the beginning of a circuit, there must be another wire to complete the circuit. Regardless, all hot wire should be treated the same: do not touch hot wire unless there is no connected and operating power source. However, other hot wires can red, blue, or yellow, although these colors can indicate a different function besides powering an outlet. This is the main color of hot wire for most homes. Hot wire is identified by its black casing. Acting as the first instance of a circuit, they are always carrying electricity, meaning it is dangerous to touch a hot wire while there is a power source feeding it. It carries the current from the power source to the outlet. Hot wire is used as the initial power feed to a circuit. Follow our guide below to better understand your electrical system! Hot Wire It is recommended you understand each component’s capabilities.įor Milwaukee homeowners seeking electrical wiring tips, Roman Electric has assembled a guide on hot, neutral, and ground wire. These three components work in tandem to distribute power throughout your home, as well as help maintain electrical safety. The answer becomes clearer when we look at the three roles wiring must fulfill: hot, neutral, and ground. But how does wiring manage to transport electricity? Wiring is how electricity is distributed throughout your home, arguably making it the most crucial part of your electrical system. I'm just at a loss.Before you perform any project or home improvement on your electrical system, you must have some understanding of how it works. I hope a squirrel or mouse didn't chew the wires in between the outlets. Any information would be greatly appreciated to track this down. I have tested all GFCI outlets and they are all okay(they are not on this circuit), I have checked the wiring at the smoke detectors as well. I have 120 volts from hot to neutral at the breaker. This is getting very frustrating but I hate to call an electrician if I don't have to.I know for sure the outlets are wired correct and they are all new and all the connections with wire nuts behind the outlets are tight and connected as well as the connections at the light switches. 103 volts hot to neutral and 17 volts neutral to ground. I have all the outlets reinstalled and I have not touched them this morning except to probe them with my DMM. It was the same way this morning when I was testing them. For the last 2 days I have had 120V on hot to ground, and 120 volts on neutral to ground, and 0 volts hot to neutral. I have also verified they are all hooked up correctly. I have replaced all the electrical outlets on the circuit and used the screws instead of the back stabs. So that one outlet had enough power to light that bulb for a split second even thought our pellet stove already had no power. My wife turned on a candle warmer (just a 25w light bulb to melt wax and the bulb blew out (on the now bad circuit). We came home from work and the power was out to one small bedroom and 3 outlets in our living room. I have 7 outlets and 3 light switches with No power. I have an open neutral circuit that I am trying to trace the broken neutral wire.
