According to the U.S. Energy Information Administration (EIA), “In 2016, customers experienced an average of 1.3 interruptions and went without power for four hours during the year.” As the demand for reliable energy grows, so too does the demand for transfer switches. Using switches in your equipment helps to keep your system fully protected by interrupting the current or diverting the current from one conductor to another. In doing so, separate circuits can be maintained within one system and emergency systems will remain powered without any interruptions.

To help streamline and accelerate the transfer switch testing and certification process for international market access, UL offers the UL and C-UL Mark for North America, as well as a UL Certified Mark to International Electrotechnical Commission (IEC) standards for markets outside of North America.

With combined testing and certification of transfer switches, you can decrease time and cost by reducing the number of required samples and the time in the laboratory.

Utilizing combined testing and certification offers:

  • Single submittal for transfer switch devices to be tested against multiple standards resulting in multiple country marks and certifications
  • Expected overall cost savings when combining investigations versus independent testing to IEC/EN and UL standards
  • Reductions in sample requirements and costs

UL offers testing and certification to UL 1008, the Standard for Transfer Switch Equipment, CSA C22.2 No. 178 and IEC 60947-6-1 for all your transfer switch equipment.
