The neutral conductor at sub panels must be isolated or kept separate from the grounding conductor to prevent the possibility of creating parallel paths for current flow. This separation helps to maintain the integrity of the grounding system and reduce the risk of electrical hazards.

Can you tie the neutral wire on a sub feed to another panel to the main neutral lug?
No, the neutral wires from different panels should not be tied together at the main neutral lug. Each panel should have its own separate neutral connection to the main service panel to ensure proper grounding and to prevent potential hazards such as ground faults. Mixing neutral wiring from different panels can cause electrical imbalances and safety issues.
How do you hook up a 4 wire double pole box from the power of a sub box with no neutral BUS?
If the sub box does not have a neutral bus, you will need to connect the neutral wire directly to the corresponding terminal on the 4-wire double pole box. Make sure to follow the correct color-coding for the wires and consult a professional electrician if you are unsure about the correct wiring configuration.
Why are the GFCI breakers nuisance tripping in your 100 amp sub panel- is it because neutral bonded to ground?
Nuisance tripping of GFCI breakers in a sub panel may be caused by a variety of factors, such as moisture exposure, improper wiring, or a ground fault in the system. If the neutral is improperly bonded to ground in the sub panel, it could also cause nuisance tripping as the GFCI breakers may detect a ground fault when there isn't one. It's important to ensure that the neutral and ground are properly separated in sub panels to prevent such issues.
On a older clothes dryer that has a three-wire cord where does the bare wire connect in the subpanel - on the neutral buss or the ground?
Answer for USA, Canada and countries running a 60 Hz supply service. WARNINGDo not use 2 conductor with ground cable to feed a 3 prong 120/240V dryer outlet. The outlet is ungrounded, and the third conductor is neutral not ground. Your ground wire must be sheathed by code. You cannot use the bare neutral conductor as ground. Another answerYou should not connect a three wire circuit for a dryer to a sub-panel, it should go all the way back to the main panel. The code never allowed a three wire circuit with a bare neutral to go to a sub-panel. By connecting the three wire cable to the sub-panel you take the chance of energizing the enclosure for the sub-panel if something were to happen to the grounding conductor from the main panel. Four wire circuits were required for dryers anytime they originated from a sub-panel, now the code requires all dryer circuits to be four wire: two hots, neutral and grounding conductor.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Is the neutral bus bonded to the equipment ground in a subpanel?
Definitely not. The neutral wires must be put on the neutral buss and that is the only place that they are to be terminated in a distribution panel. In a distribution panel there is no ground buss, it is just the metal enclosure that is used. The ground wire is only used to return a system fault back to the distribution panel to trip that circuits breaker.Distribution panels typically have two "busses"-- one for ground and one for neutral. These are terminal strips where the ground and neutral wires are connected. In some panels, these busses are electrically connected or "bonded." In other panels they are isolated. Most panels come with an optional "bonding screw" that can be installed or removed depending on whether the busses need to be connected. NEC is very specific on when these busses are to be connected. Ground and neutral busses should only be bonded at the main panel where the service enters the building. Other distribution panels will have separate ground and neutral busses and they should be isolated electrically--connecting these is a commonly seen mistake.I believe the question refers to the case where the two busses are properly bonded together, so are electrically equivalent. Then is it acceptable to have some ground wires on the neutral bus and vice-versa. Electrically it will work, but code or electrical inspectors may deem it to be confusing or sloppy practice and reject the installation.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Where should the grounding electrode conductor and the grounded circuit conductor of the wiring system be joined?
Answer for USA, Canada and countries running a 60 Hertz supply service.The grounding electrode conductor is brought into the main disconnect section of the distribution panel and a connection is made to the neutral block. The terminations in the panel at this point are two incoming "hots" to the main breaker and a neutral wire to the neutral terminal block. In the neutral termination block there is a ground screw that screws through to the distribution panels metal enclosure, there by making the metal enclosure the same potential as the ground plate or rods and the neutral wire that comes in from the street. The grounded circuit conductors of the wiring system are terminated on a separate ground buss that is located in the circuit breaker section of the panel. This buss is bolted directly to the rear of the distribution panel's metal enclosure in the circuit breaker section of the distribution panel. This ground buss is at the same potential as the ground electrode conductor above because of the grounding screw that connects the neutral block to the metal enclosure. Code requires when wiring sub panels within the same building that the neutral block screw be taken out of the circuit and a separate ground wire be run directly from the main distribution panel. This is to prevent any short circuit currents from the sub panel traveling back on the sub panel feeder's neutral wire.

Do the grounding conductors and bonding conductors ever connect to a common point?

Your neutral bus is "bonded" to the Ground bus only at the main panel. When you run branch panels you do not connect neutral to ground in these branch panels, only the main panel. There is typically a screw in an electric panel where the bonding occurs.

How do you make floating ground in 100 amp sub panel Sub panel 30' from main panel and is grded to 2nd 10' rod wired to 1st 10' rod at the main panel. GFCI bkrs are nuisance tripping in bsmt location?
If the sub panel is in the same building remove the bonding screw that bonds the neutral bar to the panels enclosure. Remove the ground from the second ground rod. The sub panel is grounded by the ground wire from the sub panel's feeder. If the panel is separate from the main building treat the sub panel as a separate service. It will need its own ground rods and ground wire from the rods to the neutral bar of the sub panel. Leave the bonding screw in. There will be no ground wire in the conduit between the two services.

Are the neutral and ground bonded in a sub-panel of an out building?
No, in a sub-panel of an outbuilding, the neutral and ground should be kept separate and not bonded together. This is to prevent the potential for ground loops and to ensure proper functioning of the grounding system.
How do you wire floating neutral in sub panel?
To wire a floating neutral in a sub panel, you need to ensure that the neutral bar is not bonded to the panel enclosure. This means you should not connect the neutral wire to the panel's metal casing. Instead, connect the neutral wire to the isolated neutral bus bar within the sub panel. Double-check the manufacturer's instructions for proper installation.
Can ground and neutral wires go to same busbar in panel?
In the main panel, the ground and neutral wires should be connected to separate busbars for safety. This helps prevent the mixing of neutral and ground current, reducing the risk of electric shock and fire hazards. In subpanels, the ground and neutral wires must be kept separate as well.
