Safety Testing and Compliance Verification for Busways
The International Electro-technical Commission (IEC) 61439 series of standards provides a frame work to meet the needs of all associated stake-holders in today’s Electrical assemblies Global Supply Chain trends (original manufacturer, assembly manufacturer, Component manufacturer, Installer, Specifier etc.). IEC 61439 series of standards considers a practical approach with multiple design verification options, clearly specifying  the safety and performance requirements for reference and use by  Engineering consultants, Manufacturers, planners, system engineers, testing lab and end users in order to define the protection objectives for people and  plants in electrical installations. This standard has now been widely accepted Globally and more than 25 countries across the world have either adopted, or harmonized their national standards with the IEC 61439 series, making it truly international for testing and certification of assemblies including busways. The IEC 61439 series applies to low-voltage switchgear and control-gear assemblies, for rated voltage up to 1,000 V (AC) and 1,500V(DC).

UL Standard for Safety for Busways (UL 857)
In North America, UL 857 / NMX-J-148-ANCE / CSA C22.2 No. 27 is the harmonized tri-national Safety Standard for Busways with NMX-J-148-ANCE (3rd edition) for Mexico, CSA C22.2 No. 27 (6th edition) for Canada, UL 857 (13th edition) for USA. The first edition of UL 857 was published in 1948.  The requirements have been developed to ensure compliance with the National Electrical Code (NEC), NFPA 70.  Application within the NEC includes installations in accordance with Article 368 (2017 Edition) and use in Service Entrance applications (NEC Article 230).  UL 857 was harmonized with the Canadian Standards Association (CSA) and the Association of Standardization and Certification (ANCE) in 2001 to ensure compliance with the Canadian Electrical Code (CE Code – CSA C22.1).  UL 857 is the American National Standard for Busways as accredited by the American National Standards Institute (ANSI).

Benefits of UL Type Testing and Certification Services.
• Demonstrates Compliance / Verification to applicable safety standard as required by Engineering consultants / specifiers and end users.
• UL Type test certificates, Test Reports and UL mark certification are well accepted by stakeholders including regulatory organizations, Manufacturers, Specifiers and have International Recognition.
• Helps in Risk and Plant Safety Management for specifiers and Installers.
• Type test Flexibility:  Specific type tests can be added or updated depending on the needs of the specifier / engineering consultant / end user or based on application if additional tests are required later or in case of standards revision in case of UL Selected type test programs after UL’s engineering review.

UL mark certification programs to IEC and UL standards consider unique product safety due diligence approach through
• Detailed product construction review / documenting product construction, ratings, marking and critical components.
• Follow-up verification of products at manufacturer’s facility through un-announced inspections for construction compliance to the ones originally evaluated.
• Mitigation of risk of counterfeits.  
• On-line traceability and verification of certification at

This workshop will provide you with the first hand, real time, industry critical information. It not only covers IEC and UL standards but also address specific topics intended to help you create and/or install safe products, increase efficiency and provide a faster time to market.
