What is UL 508A?

The UL 508A certification is a third-party certified standard for the assembly and manufacturing of industrial control panels. Contract manufacturers must assemble and adhere to the requirements to offer UL-certified project services. Industrial control panels with the UL 508A certification should successfully include listed critical components, proper spacing, regional electrical codes, circuit protection protocols, and correct identifiable labels. In meeting such specifications and necessary inspection, manufacturers can place the UL mark of approval for the respective control panels. The UL 508A certification and marked products are beneficial to both manufacturers and customers as it provides additional accountability and safety in the production and service of industrial control panels. The four main benefits of the certification include company credibility, component selection, safety, and circuit protection.

With third-party certification, MIS gives customers complete transparency and credibility for each designated project. The UL guidelines highlight assembly procedures to establish the reliability of certified manufacturers. Additionally, manufacturers can widen the accessibility of industrial control panel projects and ultimately gain more customers.

Component Selection

With the presence of UL certification, manufacturers must use particular components within control panel assembly and design for the highest efficiency level. Listed on UL sources, the critical components minimize productivity errors while maintaining control panel assembly time. All in all, customers are knowledgeable about the possible components, creating further design transparency.

In addition to proper spacing and labeling requirements, a UL certification creates an additional layer of product protection and employee safety. All components and conductors must contain standard labels for easy identification and assembly. Similarly, all industrial control panels must match electrical spacing specifications to increase safety precautions.

Circuit Protection

UL-certified panel projects must incorporate a required circuit protection standard to limit potential electrical shock incidents to both the panel and its users. Additionally, manufacturers calculate short circuit current ratings to mark the lowest rated device on each panel.

Take “MIS” Control

Overall, MIS ensures all customers have the highest quality control panels that meet the UL 508A certification protocol. Customers seeking certified industrial control panels and other unnecessary certification projects are guaranteed product safety and efficiency from MIS.

Five Initial Steps Before Panel Assembly

   |   By  |  0 Comments

5 Initial Steps Post

Above all, with every assembly comes the steps before wiring electrical connections. Each step is vital in not only assembling a reliable finished build but also one that meets all customer specifications. Whether assembling a simple panel or a complex electrical system, every customer needs to know the process, and every manufacturer needs to be transparent about their operations. This post refers to the steps before assembly; for a look at the steps during assembly, check out the MIS 5-Step Manufacturing Plan, click here.

Discussion Discussion

Before diving straight into a new project, thorough discussions with the manufacturer determine the scope, functionality, and longevity of the build at hand. Additionally, these conversations decide if that particular provider is the right company for the job, making this the most important out of the steps. In that case, you should ask as many questions as you need to analyze the potential relationship; these questions should include:

            • How transparent is communication throughout the project?
            • What kind of certifications are in place / how do they benefit me?
            • Is the equipment up-to-date?
            • What other customers and industries do you service?


Given that you have chosen the perfect provider, they take over the project, starting with the initial quote. At this point, the quoting process involves a collaboration between the sales team, quoting department, manufacturing floor, and company leaders, so depending on the scope of the work, the timing of this step varies. Due to detailed discussions about the assembly needs, along with assessing their own capabilities, the manufacturer will add significant points to the document, including:

  • The provider’s business details
  • Breakdown of costs with total
  • Space for variations and revisions
  • Payment terms and conditions
  • Preferred payment method
  • Schedule of work with the document expiration date
  • Customer signature area



Bid PrintsReview Bid Prints

During the above step, providers necessitate further cost and power breakdowns in the form of bid prints for high-level projects. Compared to the quote, a bid print would include deeper details for all aspects of the build, with the agreed-upon work process becoming non-negotiable. For this amplified description of services, the provider must take specific actions to assess themselves before taking on the job, such as:

                  • Assess profitability
                  • Determine definite capability
                  • Review past bids/success
                  • Consider long-term strategy
                  • Prioritize a breakdown of risks


Review Build PrintsBuild Prints

Finally, when the customer approves the quote or bid, analysis of the building process begins. This internal evaluation of both equipment and personnel guarantees the proper steps are completed by the best method possible. Comparing automatic to manual assembly while judging workers’ skills only benefits the time frame and accuracy of the final product. Specifically, building to client work instructions, or build-to-print materials, gives power to the client’s vision; these prints may contain:

  • Assembly drawings
  • Bill of Materials
  • Controls programming
  • Lists of components
  • Descriptions of final use



Wiring MethodsWiring Methods

At this time, electrical machine tool equipment may vary from simple, single-motor machines with repetitive operations to huge, complicated automatic machines, which contain highly complex electrical control systems. Typically, these machines are specially designed, wired with specific intentions, tested by the builder, and then erected in the plant. For this purpose, based on the required certifications and intended use of the panel, manufacturers must install wiring based on these elements:

              • NEC vs. NFPA 79 requirements
              • Wire color and specific use
              • Exceptions to allowances
              • Panel vs. Machine wiring
              • Enclosure type
              • Materials used
              • Customer specifications


Overall, using these initial steps to build a solid relationship between customers and MIS Controls is the most significant benefit. If providers go through these steps by honestly relaying their capabilities and requirements for the customer’s project, then the best plan is set forth. In turn, with a specific plan established by the quote or bid, the particular intentions for the build come together in the physical assembly work.
