Category: Neutral & Ground Bars
When it comes to electrical safety, two often-overlooked components inside many panels are the neutral bar and ground bar. At Electrical Liquidator, our dedicated category of Neutral & Ground Bars offers hard-to-find, quality parts ideal for repairs, replacements and upgrades.
What Are Neutral and Ground Bars?
In most electrical panels, you’ll find separate metal strips or rails: one called the neutral bar and one called the ground bar.
- The neutral bar is where all the neutral conductors (white wires) terminate, enabling a return path to the service.
- The ground bar is where you attach grounding conductors (green or bare wires) and bonding conductors, which ensure that stray currents or fault currents are safely diverted.
While they may appear similar, mixing them up or using the wrong component can affect safety, code compliance and performance.
Why They Matter?
- Safety & fault handling: A properly installed neutral bar ensures that the neutral return paths are secure; a correct ground bar ensures bonding and grounding are done properly. This helps protect people and property in case of faults.
- Code compliance: Most jurisdictions (for example under the National Electrical Code/NEC) require proper grounding and bonding — which means the ground bar must be correctly configured and the neutral bar isolated in certain panel types.
- Panel repairs or upgrades: In the case of legacy panels, corrosion, physical damage or missing bars are common issues. Having access to quality replacements means you can bring panels back to safe working order rather than replacing the entire unit.
- Hard-to-find compatibility: For older or obscure panel brands/models (for example panels that require special bar configurations), sourcing the correct neutral/ground bar can be a challenge. That’s where a specialist supplier like Electrical Liquidator helps.
Our Featured Products
Here are three standout products in our neutral/ground category – each with its ideal use case and link to shop.
- Neutral Bar – The standard neutral bus bar often used in many panel interiors. A go-to choice when you simply need a direct replacement for a damaged or missing neutral rail.
- Misc. Neutral Bars – For odd-ball or less-common panel models and manufacturers. If you’re repairing an unusual panel or cannot locate a standard model, this miscellaneous neutral bar listing supports a wider range of applications.
- Misc. Ground Bars – The grounding equivalent; ideal when you need a ground bus (or additional ground bar) for bonding conductors, especially in panels with multiple circuits or servicing expansions.
How to Select the Right Bar for Your Panel?
To choose the right neutral or ground bar, follow these steps:
- Identify your panel brand and interior model – Many panels (especially older ones) have bar mounting patterns, screw positions or lug types that differ. Make sure your new bar aligns with the original.
- Check required capacity – How many conductors will you land? Are you expanding circuits or adding sub-feeders? If so, you may need a bar with more screw/lug positions or a heavier gauge.
- Determine isolation requirements – Some panels require that the neutral bar be isolated from the panel enclosure (especially in sub-panels), while the ground bar is bonded to the enclosure. Make sure you follow appropriate wiring practices.
- Match material and finish – Corrosion resistance, copper or tin-plated surfaces, and secure mounting matter for long-term reliability.
- Install correctly – Turn off power, remove the panel cover, attach the new bar securely, restore all conductor terminations correctly (neutral conductors on neutral bar; grounding conductors on ground bar), then replace panel cover and restore power.
Common Use Cases
- Panel repair in homes: A neutral bar replacement is a cost-effective solution when the original bar is cracked, missing lugs or overheating.
- Upgrading older panels: When converting or expanding panels (for example adding circuits for new loads), you might need additional ground bars (via the “Misc. Ground Bars” listing) to accommodate more conductors safely.
- Legacy or specialty panels: Some older panels (e.g., obscure manufacturers) require “miscellaneous” options because standard modern bars don’t fit the unique bus layout; that’s where the “Misc. Neutral Bars” help.
- Code compliance & inspection readiness: Preparing for an inspection? Having correctly installed and identified neutral and ground bars helps ensure your panel meets bonding/grounding requirements.

Frequently Asked Questions (FAQ)
Q: Can I use a neutral bar interchangeably as a ground bar?
A: No – while they may look similar, neutral bars and ground bars are designed to serve distinct roles and often have different mounting/connection rules. Using the wrong bar can violate code and reduce system safety.
Q: In a sub-panel, do I need separate bars?
A: Usually yes. In a sub-panel you typically isolate the neutral and bond the grounds to the enclosure. That means the neutral bar must be isolated and the ground bar bonded. Make sure to follow local code and the panel manufacturer’s instructions.
Q: Why should the neutral bar be isolated in some panels?
A: Because in many systems the only permitted bonding point between neutral and ground is at the main service disconnect. In sub-panels, bonding them again would defeat the purpose of separate grounding paths and could cause unwanted currents on grounding conductors.
Final Thoughts
Whether you’re repairing an older panel, upgrading or simply ensuring your system remains safe and code-compliant, selecting the correct neutral or ground bar is a critical step. With the right bar in place – and proper installation – you restore peace of mind and protect your circuits, your equipment, and your property.
