It provides a 120 vac current source. The neutral wire forms a part of the live circuit along with the hot wire.
A white wire being used this way should be marked but it might not be.
Hot ground wire. The standard wiring configuration uses three cables or wires. Electricity may still be inside a plugged in device causing a greater chance of electrical shock upon handling the item. The hot wires can be black and any other color besides white gray or green.
So be careful with 220. Active 2 years 6 months ago. Each plays an important role in getting electricity where it needs to go safely.
Wrong breaker because he marked rthe box wrong or pulled off a different line than he thought he was using. It provides the return path for the current provided by the hot wire. The white wire is the neutral wire.
Hot and ground wires that are reversed can be dangerous because the switch that is meant to break the hot wires connection does not break the ground wire when it is hot. Proper electrical grounding is critical. The black wire is the hot wire.
If you have a three wire 220 volt setup the white wire can also be hot. I sat there dumbfounded for the better of 30 minutes trying too determine what went wrong. Green or bare wire is still ground.
The hot neutral and ground wires. This is a safety feature in case the hot or neutral wires somehow come in contact with metal parts. If the hot wire touches the metal casing then the electricity will now flow through the ground wire instead.
Ask question asked 4 years 3 months ago. In a 4 wire 220 volt setup white should be common. Hot and then while i hooked up my ground it popped the breaker.
With power on the line you turned off both the wrong circuit breaker and the wrong switch. What to do if there is no ground wire how to connect ground a ground wire to a metal box a light switch or a receptacle or connect ground wires together. If the hot wire comes into contact with both the neutral and the ground then it will flow through both wires back to the source but as the ground has less resistance more current will flow through it.
The copper wire is called the ground wire because it is connected to the earth either directly or through another grounded conductor. I hooked everything up excluding the ground and it all works but. In contrast the ground wire is connected to any metal parts in an appliance such as a microwave oven or coffee pot.
Ground wire is hot drop ceiling carrying current. The hot wire carries the power from your homes service panel to all of your light fixtures switches and outlets. Ground wire would be hot because someone wired the thing wrong or there is a short in it that is feeding to the ground wire like it is supposed to.
