Limited Production Certification (LPC)

We provide Limited Production Certification (LPC) for manufacturers of electrical equipment and electrical machines to be sold in North America.

This certification applies when only a few pieces (potentially just one) of the equipment are made.

The evaluation is performed at your production location, anywhere in the world, and includes applicable testing, an inspection of the equipment, the components used, the markings and the associated drawings. Once it has been certified and the ETL LPC label has been attached, your product can be sold anywhere in the United States and Canada. The local inspection body then checks the correct assembly and the correct electrical connection of the equipment.
