UL 508A Control Panel Manufacturer
Custom industrial control panels for North American projects. PLC, VFD, motor, pump and automation panels engineered from your SLD, BOM and project specifications.
Riches Power Tech designs and manufactures custom industrial control panels for North American applications, including PLC control systems, VFD panels, motor control panels, pump control panels and machine automation systems.
Our engineering team works from customer-provided single-line diagrams, electrical schematics, bills of materials, equipment schedules and project specifications to develop control panel solutions suited to the application.
For U.S. projects, panel construction and component selection can be engineered around applicable North American requirements, including UL 508A, NEC and NFPA requirements where applicable to the project.
Custom Industrial Control Panels
Industrial control panels are often different from standard electrical distribution equipment. The panel may need to integrate programmable controllers, variable frequency drives, motor starters, relays, power supplies, disconnects, terminal blocks, safety devices, communication equipment and field wiring interfaces.
Riches Power Tech provides custom control panel engineering based on the customer's application and electrical documentation. Typical panel configurations include:
- PLC control panels
- VFD control panels
- Motor control panels
- Pump control panels
- Machine control panels
- Automation control panels
- HVAC control panels
- Process control panels
- Dust collection control panels
- Conveyor control panels
- OEM machine control panels
- Industrial automation panels
Panel architecture can be developed according to the required control logic, power distribution, I/O requirements, communication system and field-device connections. The final configuration depends on the project specification and customer-approved design.
UL 508A Panel Engineering
UL 508A is a key North American standard associated with industrial control panels. For a project requiring UL 508A, the engineering process should consider the panel's electrical construction, components, wiring, enclosure, overcurrent protection, SCCR and other applicable requirements.
Riches Power Tech can review customer documentation before manufacturing to identify important engineering requirements. Typical engineering inputs include:
Electrical Documentation
- Single-Line Diagram (SLD)
- Electrical schematic
- Control schematic
- Panel layout
Project Documentation
- Bill of Materials (BOM)
- Equipment schedule
- Motor list
- Load list
Control Documentation
- PLC I/O list
- VFD schedule
- Communication requirements
- Enclosure requirements
This project-based approach helps reduce design changes during manufacturing and allows the control panel configuration to be reviewed before production.
Electrical Ratings
Control panel ratings are determined by the project application and the equipment installed inside the panel. Typical parameters may include:
| Parameter | Typical Project Range / Configuration |
|---|---|
| Product Type | Industrial Control Panel |
| Applications | PLC, VFD, Motor, Pump, Automation, OEM |
| System Voltage | Project dependent |
| Control Voltage | Project dependent |
| PLC Platforms | Siemens / Allen-Bradley / Inovance / specified platform |
| VFD | Project specified |
| Motor Control | Starter / VFD / Soft Starter where applicable |
| Enclosure | NEMA 1 / NEMA 3R and project-specific configurations |
| SCCR | Project-specific engineering determination |
| HMI | Project specified |
| Communication | Industrial Ethernet / project specified |
| Testing | Project-specific inspection and testing |
| Documentation | SLD / BOM / drawings / test documentation as applicable |
| Certification | Subject to actual product certification arrangement |
| Market | United States / Canada / North American Projects |
Important: Actual ratings must be confirmed against the final electrical design and component documentation. Numerical values should not be assumed simply because they are common industry configurations.

SCCR and Short-Circuit Requirements
Short-circuit current rating (SCCR) is an important consideration when engineering an industrial control panel for the North American market. The SCCR of the overall panel is affected by the components and configuration used within the control panel.
The engineering process may require review of:
- Overcurrent protective devices
- Branch circuit components
- Power supplies
- Motor starters
- Contactors
- VFDs
- Transformers
- Busbars
- Terminal blocks
- Disconnects
- Manufacturer component ratings
- Combination ratings where applicable
SCCR should be determined using the applicable requirements and the actual components used in the panel.
Riches Power Tech does not assign an SCCR value simply for marketing purposes. The final SCCR should be supported by the applicable engineering calculation, component documentation and project requirements.
Enclosure and NEMA Configurations
Industrial control panels can be manufactured in different enclosure configurations according to the installation environment.
NEMA 1
Suitable for many indoor industrial and commercial applications where protection against accidental contact and limited environmental exposure is required.
NEMA 3R
Used for applicable outdoor installations where protection against rain and environmental exposure is required.
Other enclosure types may be considered according to the project environment. The final enclosure selection should consider:
- Indoor or outdoor installation
- Temperature
- Moisture
- Dust
- Corrosive environment
- Washdown requirements
- Available installation space
- Cable entry
- Heat dissipation
- Cooling requirements
Engineering Process
Our project engineering process can begin with the customer's existing electrical documentation.
Project Requirement Review
We review voltage, load, control requirements, environmental conditions, enclosure requirements, applicable standards, quantity and delivery requirements.
SLD Review
Customers can provide their Single-Line Diagram (SLD). Our engineering team can review the electrical architecture and identify the major equipment and protection requirements.
BOM Review
The customer can provide a Bill of Materials (BOM). We can review component models, ratings, quantity, availability, manufacturer requirements and electrical compatibility.

The panel layout is developed according to the approved configuration.
Electrical Assembly
Components are installed and wired according to the approved documentation.
Inspection and Testing
The completed panel is inspected and tested according to the project requirements and applicable procedures.
Testing and Quality Control
Quality control is performed throughout the manufacturing process rather than only at the end of production. Typical inspection activities may include:
Visual and Mechanical Inspection
- Incoming component inspection
- Enclosure inspection
- Component verification
- Wiring inspection

Testing procedures depend on the customer's project requirements and the equipment configuration. Any certification, listing or third-party inspection claim must be based on actual applicable documentation.
Standards and Certification
Riches Power Tech designs and manufactures electrical equipment for North American projects with consideration of applicable industry standards and project specifications.
For UL 508A projects, the specific certification or listing status depends on the actual manufacturing and certification arrangement for the product.
