When selecting hardware for an industrial control panel, The most important thing when building a UL listed panel is the hardware that we are using. Let's go through some of the main requirements that must be met when building a UL listed panel. In many cases, UL goes one step beyond these codes and has set even higher standards for panel builders. The main purpose of UL listing is to ensure that the panel meets all codes set in place by the NEC or national electric code.
When building an industrial control panel that is going to be UL listed, there are several requirements that have to be met in order for this certification to occur. We will also discuss the requirements of the manufacturing facilities where UL panels originate, and the training required for individuals at those manufacturing facilities. Today we will discuss what those standards are and why it might affect the type of panel that is being fabricated. That is given which states that panels fabricated with the intent of being UL listed A UL listed panel is simply a third party certification. Protections defined by UL 508A and different types of motor starters chosen according to the protection devices In the US there are several types of motor starters (Type A, Type B, Type C, Type D, Type E and Type F) which differ according to the protection devices used. that can be given to a panel shop located within North America. When talking about UL listed control panels, we are talking specifically about panels that are listed under the UL 508 certification For more information about the basics of industrial control panels, please see our other video which we will link in the description below. More specifically, we will be taking an in depth look at what it means when a panel is UL listed.
Today we're going to be talking more about industrial control panels.
UL 508A MANUAL GENERATOR
In order to uphold our commitment to provide our customers with safe, high-quality standby power equipment, our StormSwitch Manual Transfer Switches and TempTap Generator Docking Stations are UL 1008 Listed to ensure safe performance during times of need.Hi I'm Josh Bloom, welcome to another video in the RSP Supply education series. More and more municipalities are requiring their manual transfer switches to be UL 1008 Listed to ensure safety and reduce liability. With an ever-growing demand for safety, it is important to know the difference between the different UL certifications.
UL 508A MANUAL PLUS
This does mean that the whole assembly (enclosure plus components) has undergone testing for the intended application. UL 50 Enclosures for Electrical EquipmentĪ UL 50 Listing only certifies that the actual box is UL Listed for a specific environmental condition (Type 1, Type 3R, etc.). Instead it covers industrial control devices such as relays, contactors, motor starters, and programmable controllers. This standard does not apply to transfer switch equipment. These devices are not Listed for the purpose of transfer switches and may not meet your project’s specifications. The UL 98 standard applies to double throw or knife edge switches (air switches), and does not allow the incorporation of circuit breakers. This standard is intended for applications that are hard-wired via terminals (usually permanent) and does not contain switching equipment or controls. The inspection process is also easier when emergency power transfer switch equipment is UL 1008 Listed.
UL 508A MANUAL CODE
Non-Automatic transfer switches that are Listed under the UL 1008 standard are evaluated in accordance with Articles 517-Health Care Facilities, 702-Optional Standby Systems of the National Electrical Code (ANSI/NFPA 70) and the National Fire Protection Association Standard for Health Care Facilities (ANSI/NFPA 99).
Products with a UL 1008 certification means the whole assembly is certified and has undergone rigorous testing to ensure performance, safety, and reliability. UL 1008 is specifically designed for transfer switch equipment. The most common UL Listings on emergency power connection equipment are as follows: You may not always be purchasing what you think you are. When comparing NRTL Listings of different products, it is important to know what the appropriate UL standards are and how they apply to your specific application.
