The design and construction of custom electrical components is regulated by the National Electrical Code (NEC). Sponsored by the National Fire Protection Association (NFPA), the NEC is approved as the American national standard by the American National Standards Institute (ASNI). First published in 1897, the NEC is the decisive authority on electrical safety and its standards are used by municipal permitting authorities across the U.S. Under Writers Laboratory (UL), a global independent safety science company, is the primary certification agency for electrical components used in industrial panel control equipment and electrical components. It certifies, validates, tests, inspects, and audits products for initial and ongoing compliance; advises companies; and trains employees of certified companies.
UL 508A sets the minimum standards for devices with 1500 volts or less used in an ambient temperature of 32° to 104°. These industry standards, and the associated mark on the product, provide evidence and assurance to municipal inspection agencies that the components and control panel meet safety criteria.
BLOC Design-Build understands the importance of complying with the NEC and UL standards and the value of the UL mark on its control panels. When presented to clients, components and systems with the UL 508A certification mark are readily accepted for integration into their systems. As a leader in designing and building custom control panels, BLOC ensures that its products and production laboratory meet both NEC and UL standards.
BLOC regularly designs and builds custom control panels for a variety of instrumentation and control systems, including SCADA, for municipalities, industrial/manufacturing clients, and oil and gas producers. Using a variety of products from integrated service partners, BLOC will specify, design, and install a proprietary or nonproprietary system for each client based on its particular needs and to meet its budget and installation time requirements.
