Safety Comes First in Electrical Manufacturing

When it comes to designing housings and other components to store electrical equipment, safety considerations always come first. Sierra Pacific Engineering and Products recognizes the importance of establishing and maintaining rigid standards in our highly specialized industry and we strictly adhere to the standards set by the National Electrical Manufacturers Association and the Joint Industrial Council.

These trade groups are highly respected for their leadership role in ensuring affiliate organizations follow established regulations and laws in the design, production, and sale of electrical components. We support and promote these standards in making all of our electrical products, including enclosure hinges (NEMA hinges), which are used in industrial applications throughout the world.

We take great care in designing and engineering hinges, latches and other industrial hardware. When you purchase a NEMA enclosure or JIC box from SPEP, you can feel confident that it follows strict guidelines for the proper housing, storage and security of electrical equipment. Safety-compliant hardware that we produce for electronic enclosures includes the following:

•  Kits
