Trusted Field Listing Solutions

At Solid Ground Electric, we provide professional field listing services for electrical equipment that is not factory listed, has been modified, or is custom built for a specific job site. This service helps owners, contractors, and facility managers get the approval they need for safe operation and code compliance. If an inspector or authority having jurisdiction has asked for a field evaluation or field label, we can help you move the job forward.

Field listing is often needed when electrical equipment does not carry a standard label from a nationally recognized testing laboratory, or when that original listing no longer applies because the equipment was altered. We see this with custom control panels, industrial machinery, switchgear modifications, imported equipment, fuel system controls, specialty HVAC equipment, and one-off assemblies built for a unique application. In these cases, the equipment still needs to be reviewed for safety, installation quality, and code compliance before it can be approved for use.

Our team understands how field listing work fits into the real world of construction, renovation, tenant improvements, and industrial upgrades. We know delays cost money. We also know failed inspections can hold up an entire project. We work closely with owners, general contractors, engineers, and inspectors to identify issues early, make needed corrections, and help prepare equipment for a successful evaluation.

What field listing means

A field listing is a process used to evaluate electrical equipment in the field when standard product listing is missing or no longer valid. The goal is to confirm that the equipment is safe for its intended use and installed in line with applicable electrical codes and safety standards. Depending on the project, this can involve reviewing wiring methods, overcurrent protection, grounding and bonding, enclosure ratings, component compatibility, short-circuit current ratings, labeling, disconnecting means, working clearances, and overall workmanship.

This service is especially important for commercial and industrial facilities where custom electrical equipment is common. Many projects involve modifications that happen after manufacturing, such as adding breakers, changing control schemes, retrofitting transformers, replacing components, or integrating new systems into existing gear. Even when the work is done well, changes like these can affect the original certification. That is where a field listing process becomes critical.

When you may need field listing

• Custom-built electrical panels or control panels
• Modified switchboards, switchgear, or motor control equipment
• Imported electrical equipment without an accepted listing mark
• Industrial machines relocated from another facility
• Fuel system controls and specialty commercial equipment
• HVAC or refrigeration equipment with major electrical changes
• Assemblies built on site for a specific project
• Equipment flagged by an inspector during plan review or final inspection

If you are not sure whether your equipment needs a field listing, we can review the situation and give you practical guidance. In many cases, a quick early review can prevent bigger problems later.

Our process

We start by learning what the equipment is, how it will be used, where it is installed, and what concerns have been raised by the inspector, engineer, or owner. We review available drawings, nameplate data, manuals, one-line diagrams, control schematics, and any prior inspection notes. From there, we inspect the equipment and installation to identify missing labels, improper wiring, unsupported modifications, inadequate protection, grounding issues, or other code and safety concerns.

Once we understand the scope, we explain what needs to be corrected. Our licensed electricians can perform the needed electrical repairs or modifications, or coordinate with your team when other trades or manufacturers are involved. We focus on practical solutions that improve safety and help the equipment meet approval requirements without unnecessary extra work.

Typical correction items may include updating disconnects, correcting conductor sizing, improving wire bending space, adding proper bonding, changing overcurrent protection, replacing non-compliant components, securing wiring, improving enclosure integrity, adding warning labels, or documenting short-circuit ratings and equipment specifications. Every project is different, so we tailor our work to the exact equipment and site conditions.

After corrections are complete, we help prepare the equipment for the final field evaluation by the proper agency or authority. Our job is to make sure the equipment is ready, the documentation is organized, and the installation presents clearly for review. That can make the approval process smoother and reduce repeat visits.

What we look for

Because field-listed equipment must be safe in actual operating conditions, the review goes beyond whether the system simply turns on. We pay close attention to the details that matter in the field, including:

• Proper conductor sizing and insulation type
• Safe terminations and torque compliance
• Grounding and bonding continuity
• Overcurrent protection and coordination
• Working clearances and accessibility
• Correct enclosure type for the environment
• Short-circuit current ratings and fault protection
• Suitable disconnecting means
• Component ratings and compatibility
• Required warning labels and equipment markings
• Neat, professional workmanship that supports safe maintenance

These details matter because inspectors and evaluators need confidence that the equipment can be used safely over time, not just pass a quick visual check.

Why customers call Solid Ground Electric

Field listing issues can be stressful, especially when a project is already behind schedule. We bring real job-site experience to the process. Our team works on residential, commercial, and industrial electrical systems, and we are comfortable with everything from panel upgrades and transformers to complex controls and specialty fuel system equipment. That broad experience helps us spot problems quickly and recommend fixes that make sense.
