You need to be more specific. Is this your feed?? Is this a home run (the wire that is feeding a circuit). Anyway if this is your feed wire (the wire supplying power to your sub panel) then you will land your two hots , then you will land your ground wire on the lug that is bonded to the panel. Sometimes this is a ground bar that can be screwed to the panel itself and then your neutral will go to the bar that is not touching anything. So your neutral coming in will be tightened down to the same bar as the neutrals that are feeding the circuits. This is assuming you'r are feeding your sub panel with 2 hots, a ground and a neutral.

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.

Why can't the ground wire be connected to neutral at the receptacle instead of in the main panel?
Connecting the ground wire to neutral at the receptacle can create a safety hazard called a bootleg ground, where fault currents may flow through unintended paths. It can also cause imbalance in the electrical system and interfere with the performance of GFCI outlets. It is important to always follow proper wiring practices to ensure safety and compliance with electrical codes.
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.
Why do you isolate the neutral?
If you are working with a sub panel, there are a few reasons to isolate the neutral. Firstly, currents will then return to the main panel and service ground.
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.
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.
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.

Do the grounding conductors and bonding conductors ever connect to a common point?
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.In house wiring you have earth ground connect to the ground bus in the main electric panel. 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 is a 208 volt 3 phase electrical sub-panel wired?
Mark the phases red (phase) black (phase) and blue (phase) along with a white (neutral) and a ground (wire size depends on the main breaker amperage) the phases attach to the main breaker unless it is a breakerless panel attach the phases to the lugs on the bus bars top or bottom then connect the neutral to the neutral bus and the ground to the panel
How do you connect the wires for a 200 amp sub panel to a 200 amp main panel?
You will need to install a 4-wire feeder cable between the two panels. The two hot wires will connect to the main breaker in the main panel, the neutral wire to the neutral bus bar, and the ground wire to the ground bar. Make sure to follow local electrical codes and regulations. If you are unsure, consult with a qualified electrician.
Can you feed a 60 amp sub panel from another 60 amp sub panel?
Yes, you can feed a 60 amp sub panel from another 60 amp sub panel as long as the total connected load does not exceed 60 amps. Make sure to properly size the wire and protect the circuits with appropriate breakers to ensure safe operation of the sub panel.
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.
