The importance of getting a medium voltage certification
In the past, equipment operating above 600 volts (V) was generally considered to be under the control of the local serving utility. Recently, the responsibility for the installation and maintenance of electrical distribution has shifted from utilities to the site or building owner. This shift has caused an expansion in the requirements of the National Electrical Code (NEC) and National Fire Protection Association (NFPA) 70, as well as increased responsibility for local authorities having jurisdiction (AHJ).
If you’re a building owner who now has the responsibility of meeting these requirements, it can seem like quite a challenge. How do you keep up and comply with the latest regulations in an ever-evolving industry?
Fortunately, we’ve designed a service to help you do that. We provide testing and certification services to cover all types of medium voltage distribution equipment. Receiving UL certification is an effective way to satisfy insurance requirements and to help ensure a code-compliant installation.
