UL 508A - Industrial Control Panels
Industrial Control Panels manufacturerd for both the US and Canadian markets
UL 508A SERVICES
JAJO Automation Services is one of a select group of UL 508A approved industrial control panel builders in the UK, certified to design and manufacture panels in accordance with recognised North American electrical standards.
UL 508A governs the construction of industrial control panels for compliance with the National Electrical Code (NEC) in the United States and Canada.
As a participant in the Industrial Control Panel Shop Program, with a qualified UL 508A technical representative in-house, we are authorised to design, build and apply UL labelling to both standard and custom control panels without the need for individual design re-evaluation. This enables our customers to confidently specify and supply fully compliant panels for projects requiring UL-certified equipment

UL508A Industrial Control Panels for Export Machinery
Designed for compliance. Built for reliability. Ready for installation
Supplying machinery to the United States or Canada often requires more than CE marking alone. Many installations must comply with recognised North American electrical safety standards, and without the correct certification equipment can be delayed, modified on site or even refused connection. A properly designed UL508A industrial control panel helps ensure your machine is accepted by inspectors and ready for installation when it arrives on site.
We design and build control panels specifically for export machinery and industrial automation applications. Whether you are an OEM manufacturer, machine builder or end user upgrading equipment, we provide practical guidance from specification through to completed panel build. Our aim is to help you meet compliance requirements first time, avoiding costly redesigns and project delays.
Panels can be supplied for new equipment, control system upgrades or retrofit projects, and can incorporate PLCs, drives, safety systems and operator interfaces as required. By working with a UL-compliant panel builder at an early stage of your project, you can be confident your equipment will meet the electrical expectations of North American customers and authorities having jurisdiction (AHJ).
When Do You Need UL508A?
UL508A certification is typically required when machinery or equipment is being supplied to North America. While CE marking satisfies European safety requirements, installations in the United States and parts of Canada are usually inspected against recognised electrical standards before they are allowed to be connected to the power supply.
You are likely to require a UL508A control panel if:
-
Your machine is being exported to the USA or Canada
-
The end user specifies UL compliance in their purchase order
-
The installation will be inspected by an Authority Having Jurisdiction (AHJ)
-
The equipment is being installed in a factory, warehouse or production facility in North America
-
Your customer’s insurer requires recognised electrical certification
-
A systems integrator or contractor requests UL-compliant equipment before installation
Without a compliant panel, machines can be delayed at site while modifications are made, components replaced or wiring reworked to meet local inspection requirements.
Why It Matters
North American inspectors do not assess machines in the same way as European installations. Even well-built equipment may be refused connection if the control panel does not meet recognised electrical construction standards. Common issues include incorrect circuit protection, unsuitable components or missing fault current ratings.
Providing a properly designed UL508A panel helps:
-
Avoid on-site modifications and rewiring
-
Prevent installation delays and additional costs
-
Give confidence to customers and contractors
-
Support acceptance by inspectors and insurers
-
Allow the machine to be powered and commissioned sooner
Engaging a UL-compliant panel builder early in a project is usually far simpler and more cost-effective than attempting to modify a machine once it has arrived overseas.

Information Required to Quote a UL508A Control Panel
Providing clear technical information at an early stage allows us to design a control panel that meets UL508A requirements without unnecessary revisions. It ensures the correct components are selected, the required Short Circuit Current Rating (SCCR) is achieved, and the panel is suitable for the intended installation.
We don’t expect every detail to be fully defined, but the following information helps streamline the process and improve accuracy:
Typically, we will ask for:
Electrical Schematics (if available)
Existing drawings or wiring diagrams provide a useful starting point, helping us understand the control philosophy and identify any areas that may need to be adapted for UL compliance.
Motor and External Load Details
Information on motors, drives, heaters, and other connected equipment allows us to correctly size components, protection devices, and internal wiring.
Supply Characteristics and Fault Current Information
Details of the incoming supply are important, including:
-
Voltage and frequency
-
Phase configuration
-
Available fault current
This information is used to determine the panel SCCR in line with UL508A and to ensure all components are correctly rated for the application.
Machine Function or Process Description
A clear overview of how the machine operates helps ensure the control system is designed appropriately, including sequencing, interlocks, and safety integration.
Installation Environment and Location
Understanding where the panel will be installed allows us to select and design the correct enclosure and thermal performance. This may include:
-
Indoor or outdoor installation
-
Ambient temperature
-
Dust, moisture, or washdown conditions
This ensures the enclosure type rating is appropriate and that internal temperatures remain within acceptable limits under normal operation.
Working With Early-Stage Projects
If some of the above information is not yet available, we can still assist.
We regularly support projects at an early stage, helping define requirements and develop a practical, compliant solution.
Why This Is Important
Providing this information early helps to:
-
Achieve UL508A compliance first time
-
Avoid redesign or on-site modification
-
Reduce project delays
-
Support smooth approval by inspectors and Authority Having Jurisdiction (AHJ)
