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.

RossTo 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.
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.
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.
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.
