UL CONTROL PANEL DESIGN & FABRICATION

An industrial control panel is an assembly of electrical and control components used to monitor, operate, and automate industrial equipment or processes.

Depending on the application, a control panel may contain PLCs, motor controls, variable frequency drives, power supplies, circuit protection, relays, industrial network equipment, operator interfaces, and connections to field instrumentation. The panel provides an organized interface between electrical power, the control system, and the equipment being controlled.

No. Industrial control panels can vary significantly depending on the equipment being controlled, operating environment, electrical requirements, level of automation, applicable codes and standards, and customer requirements.

A panel designed for a municipal pump station, for example, may have very different requirements from a robotic manufacturing cell or a panel installed in a hazardous classified location. CID designs each panel around the application while also considering installation, operation, maintenance, and future support.

Electricians frequently install, connect, troubleshoot, and modify industrial control panels, but panel design and fabrication can require specialized engineering, documentation, testing, and certification capabilities.

CID designs its panels with the installing electrician in mind, including thoughtful equipment layouts, accessible field termination points, clear labeling, and complete electrical documentation.

Motor control refers to the electrical equipment and control methods used to start, stop, protect, monitor, and regulate electric motors.

Motor-control systems can range from conventional starters and overloads to intelligent motor protection devices, soft starters, variable frequency drives, networked motor control centers, and PLC-based automation.

A variable frequency drive (VFD) controls both the frequency and voltage supplied to a motor, allowing its speed and torque to be controlled during operation. A soft starter primarily reduces the electrical and mechanical stress associated with starting and stopping a motor.

A soft starter can be a good choice when a motor normally operates at full speed but needs a controlled start. A VFD is typically used when the process benefits from variable speed, tighter process control, energy optimization, or more advanced motor-control functionality.

A UL panel shop is a control panel manufacturer participating in UL Solutions' Industrial Control Panel Shop Program and authorized to apply applicable UL Certification Marks to panels manufactured within the scope of its certification.

CID maintains UL-certified panel capabilities for general industrial control panels as well as specialized hazardous-location applications.

UL 508A is the primary standard for industrial control panels. UL 698A addresses industrial control panels relating to hazardous classified locations, typically where a panel installed in an ordinary location contains intrinsically safe circuits extending into a hazardous location.

NNNY is a UL product category covering control panels and assemblies for use in hazardous locations themselves. CID's panel shop has capabilities covering UL 508A, UL 698A, and applicable NNNY hazardous-location panel applications.

A hazardous classified location is an area where flammable gases or vapors, combustible dusts, or other ignitable materials may create an increased risk of fire or explosion.

CID has extensive experience with NEC Articles 500-503 requirements and can help customers and electricians develop appropriate control-panel and field-installation approaches for hazardous applications.

A purge and pressurization system uses a protective gas, commonly clean air or an inert gas, to reduce or remove a potentially hazardous atmosphere from an enclosure and maintain positive pressure to help prevent the surrounding hazardous atmosphere from entering.

The appropriate protection technique depends on the area's classification and the equipment being installed.

PLC modernization is the process of replacing or migrating aging control-system hardware and software to a current, supportable platform while preserving the required operation of the process or equipment.

CID has experience modernizing systems based on Rockwell Automation, Siemens, Modicon, and other industrial control platforms.

Obsolete control hardware should be evaluated before a component failure or support issue forces an emergency replacement.

CID can evaluate an existing system, identify lifecycle risks, and develop a phased or complete modernization strategy that considers operations, maintainability, spare parts, cybersecurity, and downtime requirements.

Yes. CID designs and integrates control systems for industrial robotics, motion control, and other specialized automated machinery, with experience across FANUC, Epson, ABB, Nachi, and DENSO robotic systems.

Yes. CID can provide build-to-print panel fabrication using customer-supplied electrical drawings and specifications, allowing CID to function as an extension of an existing engineering or manufacturing organization.

Yes. CID can provide complete electrical design and panel fabrication when finished electrical drawings are not available, starting from equipment specifications, P&IDs, I/O lists, sequence descriptions, existing drawings, or defined operating requirements.

Yes. CID can develop electrical drawings and fabricate panels in accordance with established customer standards, including preferred manufacturers, drawing formats, naming conventions, wire and terminal numbering, labeling practices, and title blocks.

Yes. CID can provide supplemental engineering and panel-fabrication capacity for customers who need additional resources to support project schedules or production demand, without requiring a compromise on standards or workmanship.

Documented processes and quality checks are incorporated throughout the project, not just a final inspection after fabrication, to promote consistency, traceability, repeatability, and continuous improvement.

No. CID supports customers and projects beyond its local Bend, Oregon area and serves customers throughout the West Coast. Panels can be engineered, fabricated, tested, documented, and prepared for shipment before arriving at the project site.

Yes. CID can review your panel requirements and prepare a proposal so you can evaluate cost, schedule, scope, and technical approach before moving forward. The more information available, such as electrical drawings, BOMs, and required delivery dates, the more accurately CID can evaluate the project.
