Control Panel Manufacturers
Last updated: January 2026
This directory lists 119 control panel manufacturers across the United States, from highly specialized custom design-build integrators to high-volume contract assemblers.
Buyers frequently engage these manufacturers to solve critical problems such as standardizing industrial automation across multiple facilities, upgrading obsolete legacy control systems, or developing new machine controls requiring precise HMI integration and robust PLC programming. The goal is often to enhance operational efficiency, improve safety through compliance with standards like NFPA 79, or ensure reliable performance in challenging environments that demand specific NEMA enclosure ratings.
Supplier types in this sector vary significantly. You'll find pure build-to-print shops focused on efficient assembly of customer-provided designs, often excelling at high-volume runs. Others are full-service control system integrators that offer engineering design, software development, arc flash studies, and complete factory acceptance testing (FAT). The distinction often lies in their engineering capacity, their willingness to take on design responsibility, and their typical project scope, from small standalone units to large-scale distributed control systems.
Before engaging a control panel manufacturer, buyers should have their project's scope clearly defined, including detailed electrical schematics, Bill of Materials, and functional specifications where possible. Suppliers expect clear communication regarding environmental conditions, required certifications like UL 508A, and desired levels of factory acceptance testing. Being prepared with this information streamlines the quoting process and helps ensure an accurate build.

How to Choose a Company
- Verify their specific certifications: For panels installed in the US and Canada, demand proof of UL 508A and CSA certification marks directly applied by the manufacturer, not just a promise to achieve them. For panels destined for Europe, ensure they can apply the CE mark in accordance with the Low Voltage Directive.
- Assess their engineering depth beyond assembly: Determine if you need pure build-to-print or if you require design assistance, PLC programming, or complex HMI integration. A strong design-build firm will discuss arc flash mitigation strategies and offer a full suite of software development services.
- Evaluate their understanding of environmental requirements and NEMA enclosure ratings: Do not assume a standard enclosure will suffice. Discuss the specific operating environment (e.g., washdown, dusty, hazardous) and confirm their experience with corresponding NEMA or IP ratings (e.g., NEMA 4X for corrosion resistance, NEMA 7/9 for hazardous locations).
- Scrutinize their documentation and quality control processes: A red flag is a manufacturer unwilling to provide detailed wiring diagrams, component layout drawings, and a comprehensive test plan for their panels. Insist on seeing samples of their typical documentation package and discussing their in-process and final inspection protocols.
- Clarify their approach to component procurement and inventory: Ensure they have established relationships with key automation component suppliers (e.g., Rockwell, Siemens, Schneider Electric) and can manage lead times effectively, especially for specialized items like specific drives, relays, or safety PLCs to avoid project delays.
Frequently Asked Questions
What's the difference between UL 508A and NFPA 79 for my control panel?
UL 508A is the Standard for Industrial Control Panels, focusing on the electrical safety of the panel itself, including component selection, wiring methods, and enclosures. NFPA 79, the Electrical Standard for Industrial Machinery, focuses on the electrical safety of the entire machine, including how the control panel integrates with other machine elements, emergency stops, and interlocks. Your control panel manufacturer should be compliant with UL 508A for the panel, and understand NFPA 79's implications for the machine it will control.
Do I need an arc flash study for my new industrial control panel?
While the control panel manufacturer builds the panel, an arc flash study is typically performed on the overall electrical system where the panel is installed. However, a knowledgeable manufacturer will consider design elements within the panel, such as component placement and bus bar design, that can mitigate arc flash hazards. They should be able to specify arc-resistant components or offer design recommendations that contribute to a safer system, often working with your facility's electrical engineers or third-party consultants.
How does a control panel manufacturer handle proprietary PLC programming and intellectual property?
For design-build projects, manufacturers will often develop PLC and HMI programming. It's critical to establish intellectual property (IP) ownership upfront through a clear agreement. Ensure the manufacturer provides commented code, original project files, and detailed documentation. For build-to-print projects where you provide the program, verify their process for securely loading and testing your proprietary code, often involving dedicated programming stations and strict access control.
What NEMA rating do I need for an outdoor control panel, and how does that affect cost?
For outdoor applications, you'll typically need a minimum of NEMA 3R, NEMA 4, or NEMA 4X. NEMA 3R protects against rain, sleet, and external ice formation. NEMA 4 adds protection against windblown dust and hose-directed water. NEMA 4X provides additional corrosion resistance, crucial for environments with chemicals, salt spray, or frequent washdowns. Higher NEMA ratings involve more robust materials, seals, and construction (e.g., stainless steel for NEMA 4X), which directly impacts material and labor costs, making the panel more expensive than an indoor NEMA 12 equivalent.
