I've heard "You can touch the neutral wire/bar in the breaker box and not get shocked. Only the hot can hurt you." If the circuit is complete and current is flowing, can't you receive a shock? Overfilling Electrical Boxes Mistake: Too many wires in a junction box. Stuffing as many wires as possible into an electrical box is a fire hazard. Solution: Follow box fill requirements. The NEC limits the number of wires, . The faulty neutral on the other circuit will cause overload of the wire ampere carrying capacity when power is being used from both circuits but the one good neutral has to .When live and neutral connections are switched, it creates substantial and dangerous hazards: Electrical Shock Risks. The live wire may remain energized even with switches turned off. If light switches no longer disconnect power, .

switching live and neutral connections
The neutral wire should always be grounded to avoid a buildup of voltage that could be hazardous. The incorrect installation of a neutral wire can lead to sparking, overheating, or potential electrical fires. Always hire a trained .The neutral wire is like the return path for where electricity flows, allowing for a safe and efficient circuit. The neutral wire typically looks like a gray, blue, or white wire and is connected to the earth at the electrical panel, providing voltage .
Neutral wires are mainly found in newer homes (built after 1985) and are required by most modern US electrical codes. Don’t get shocked! To avoid an electric shock, always turn off the voltage to a switch or outlet at the .
Neutral is the return path of the current, and ground wire holds the fault current to trip the breaker in protecting the person and the facility. The neutral and ground should never be bonded together in the facility except for the main panel.
If a hot wire accidentally makes contact with grounded metal like a junction box or you have damaged insulation allowing bare wires to reach grounded pipes or supports, it places full 120V relative to panel potential onto the return neutral.Neutral wires burn because of a loose connection, shared neutral, overloading, coiling, and lightning. 1). Loose Connections. Neutral wires burns due to loose connections. A loose wire .Choosing wire gauge based on overcurrent protection is to protect the building wiring method, which essentially refers to everything between the breaker and the junction box. Someone adding a load can't see all of that wiring, so they need .
Clearly problem is in the junction box from hell. Crawl back to junction box from hell. Dad flips breakers one at a time until I find a wire nut that has wires from one side of the shared neutral and the completely separate circuit that's mistakenly tied to it. Separate into two respective groups and reconnect.
Sounds to me like either an open neutral or the poco forgot to ground down the neutral or a hot is grounded down instead of the neutral. If its a sub panel the panel could be miss fed in that a hot is landed on the main neutral bar and the neutral on a breaker in the main panel or what ever is feeding it. I noticed that the ground wire (from my house) is bare in the box and the ground wire coming from the Lutron Casetta has green insulation. . If the ground wire touched the neutral, there would be no obvious effect. When the circuit was energized, current which normally flows back to the panel via the neutral would be split between the neutral .The white wires are just joining the neutrals between two romex cables running in the wall- just like a junction box (which is code in my area). Switch boxes and outlet boxes are commonly used as junction boxes to make connections without being attached to a switch or outlet.Essentially, 2 wires are grounded, so this “neutral” wire is not dangerous if exposed to metal parts like the “hot” wire is. So to review, the neutral and hot wires are actually interchangeable as far as electrical flow through the appliance, but in America, we “polarize” the plugs to differentiate between the neutral (connected to .
Exception: For existing branch-circuit installations only where an equipment grounding conductor is not present in the outlet or junction box, the frames of electric ranges, wall-mounted ovens, counter-mounted cooking units, clothes dryers, and outlet or junction boxes that are part of the circuit for these appliances shall be permitted to be .It comes out of the ground 80 feet away as two wire with ground. It seems to be no matter how I supply hot, neutral, and ground to these three, The white wire is hot on the two wire with ground. I’m assuming there’s a buried junction box Well it has continuity where it shouldn’t. I have just installed an outdoor security light with a junction box I bought (weatherproof). I wired the old red source wire to the new brown, old black source wire to the new blue in the terminal block, but noticed the third ground wire was just exposed copper.

The neutral wire, in a house, is how current returns to the panel, and then the pole, and so on, back to the generating station. . but might fall apart in older homes with weird things going on in the junction boxes. . How dangerous is this rust and corrosion on my electric meter? 2.
"Modern home. Every box must have neutral" -- #1 not every box: some 3-way switch locations are exempt. #2 Even if neutral is present, if always-hot is not present it defeats the purpose of having neutral. Poaching neutral is Right Out. You cannot steal neutral from another cable (and certainly not another circuit).Yes, in the vast majority(99% of the time) of small residential panels, the phases will alternate vertically. Again, make sure it is not a tandem breaker(two small breaker handles on one breaker body) as this will be both circuits on the same phase, which could potentially overload your neutral wire up to 40 amps, based on the unbalanced load on each circuit.
Why is neutral and ground not precisely the same voltage? Because neutral is workin' for a living, and ground is not. You're seeing voltage drop on the neutral, which since a neutral starts at 0V, tends to lift the neutral's voltage up a volt or two. It's the same effect as a beam-style torque wrench: the heavy beam bends with the many foot .
It’s been determined that there is a bad neutral wire connection somewhere and the issue is trying to find the junction box related to the problem. Had a couple friends with electrical experience check outlets and trace from electrical panel. Also had certified electrician out twice for about 3 hours with no luck in finding a junction box.In either case, you have the provision to isolate one neutral without permanently disconnecting the rest of the neutrals. So on either case you are not violating those code. What you could not have is a neutral that is entirely dependant on .I want to connect the wiring from my shed into a junction box on the ceiling in the basement. I opened the box to see what I was dealing with, I figured it should be simple, there is only 2 wires going in. but i am confused- black to black, and .If advice given is thought to be dangerous, you may be permanently banned. . The thick ground wire in the junction box actually gets grounded to my water main coming in the house. . We connect to a exterior, buried in earth, metal water pipe to help keep the voltage on the neutral wire at zero volts. It's "earth reference". The transformer .
A few more details is you want/need them: The box is the first box from the breakers - thinking I had turned off the necessary breaker (cuz the outlets were dead; first mistake) I opened the box and disconnected all the wires (unscrewed all the wire nuts and separated all the wires - so I could pull out the 'new' outlet wires).How to figure out wires in a junction box . Hi there, I have 4 “branches” of wires coming into a box in this configuration from left to right Red, white, black White, black . Okay thank you I will try this in the morning, the white wires are neutral wires, can all 4 be wired together under one but? .A ground and neutral wire are two separate things. The problem here is that is not the right cable to use for this situation if a neutral is needed. . Going to replace a wall oven with 6awg SEU (no junction box in the prior install, just electrical-taped red wire nuts flapping in the breeze behind the oven). Home was built 1986, previous oven . I told the management company of the building that i need to chop the walls to get a new neutral to the circuit. This apartment is all pipe.. But there a friggin buried junction boxes passed the panel so going through the pipe will b impossible. My old boss used make the box as the neutral when he ran into this problem sometimes
The switches do use the push-in holes and not the screws to connect the wires. Is it possible it is a nail hit the wire and would cause these symptoms without blowing the breaker? Why does the office have 118v? The office is between the breaker box and garage. Is it possible bad neutral connections (which I understand can cause voltage drops?It has two black terminals on the right side, and one brass and one silver terminal on the left side. There are two wires coming into the junction box: one black and one red. . This is very dangerous. The receptacle must be removed as you only have the wires for the switch. . Usually just running bare ground wire to the neutral terminal . The oven wire currently is running up a wall and along a 2nd story floor joist to a junction box, only after the junction box is it in metal conduit with a ground wire bonded to neutral. . no single wire failure will create a dangerous condition. If the neutral fails, the appliance won't work but the exterior will be safely grounded .Inspect wiring connections visually for obvious black (live) and white (neutral) wires interchange. Check that ground wires are correctly bonded to metal junction boxes and fixtures. Preventing Reversed Polarity Situations. The best approach is to avoid reversed polarity completely when working with electrical systems:
Greetings, I have a 12 gauge wire (yellow) coming directly from the circuit breaker into an outlet. It's the only thing on that circuit. I need to move the outlet, so I'm going to disconnect the outlet, pull the wire through the floor (basement ceiling) and put a junction box there (I'm moving the outlet higher on the wall and don't have enough slack as is, thus I need . Ground and neutral are connected - test anywhere in the system with a multi-tester and you will get connectivity. Neutral is broken somewhere to this particular box. Since ground is connected to neutral, "fix" by connecting neutral and ground in this box. Which 100% works. But is 100% against code and can lead to dangerous situations.
