Take a look at the junction where the ground wire and the neutral enter the panel. There you should see a green grounding screw that protruded through the neutral block and into the metal enclosure of the distribution 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.
The term SN refers to a panel or disconnect switch that has solid neutral bar installed. It is a small bar that allows the service conductors to be bonded to the enclosure at that point.
The main electric panel is where neutral is bonded to ground. There is usually a screw or strap that connects the two so the same type panel could be used as a subpanel and have the neutral and ground unbonded in subpanel.
To check if an electrical panel is bonded, you can use a multimeter to test for continuity between the panel enclosure and the ground bar. If there is continuity, the panel is bonded properly. Additionally, you can visually inspect for bonding straps or conductors connecting the metal enclosure to the ground bar.
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.
Unless the panel is the Main Panel (first panel in the system after the service feed) all panels have a neutral bar. Otherwise you are missing pieces. If this is the Main Panel, the neutral bar is bonded to the ground by a bus-bar. If this is the case, neutrals should all be connected to the same side of these bonded bars. Electrically it makes no difference, however it is a good practice to keep electrical panels neat and organized. If this is not the Main Panel and there is no neutral bar, STOP, PUT DOWN THE TOOLS, CALL A PROFESSIONAL. This panel is missing pieces and may be dangerous. It is possible to have a panel without a neutral. This panel would serve only 240 volt loads where no neutral is needed, however I have not seen this done in residential applications.

A ground bar is used to connect the grounding wires of electrical circuits to the panel's grounding system, while a neutral bar is used to connect the neutral wires of electrical circuits to the panel. The ground bar is for safety, while the neutral bar is for completing the circuit.
The main electric panel is where neutral is bonded to ground. There is usually a screw or strap that connects the two so the same type panel could be used as a subpanel and have the neutral and ground unbonded in subpanel.
Assuming inside the lighting/distribution panel, the Neutral bar is "bonded" to the ground bar. Then the neutral prong (usually larger) of the receptical is then directly wired to the Neutral bar in the panel. The above technique keeps the NEUTRAL at GROUND potential, however, the metalic frame of the appliance remains UN-GROUNDED if the supply cord is only 2-wire. The NEUTRAL connection inside the appliance is not allowed to be bonded to the frame of the appliance. Therefore, the un-grounded metal frame of the appliance can become a shock hazard if there is a fault in the appliance's internal wiring
To check if an electrical panel is bonded, you can use a multimeter to test for continuity between the panel enclosure and the ground bar. If there is continuity, the panel is bonded properly. Additionally, you can visually inspect for bonding straps or conductors connecting the metal enclosure to the ground bar.
A 32 circuit main panel with a neutral bar on each side that is joined together by another bar and is grounded on each side with 12 slots of grounds requires bonding. The bonding allows the current to direct flow between the circuits and the bars.
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.
The neutral bus bar in a Stab-Lok panel BE116-32 125 amp is typically located on the side or at the bottom of the panel box. It is a metal bar with multiple screw terminals for connecting the neutral wires from branch circuits. Refer to the panel's installation manual or contact a qualified electrician for specific guidance on locating and working with the neutral bus bar.
A neutral bar is where the neutral wires from the circuits are connected, while a ground bar is where the ground wires are connected. The neutral bar carries the current back to the power source, while the ground bar provides a path for excess electricity to safely dissipate into the ground.
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.
