Comparison of Hazardous Location Standards

NEC 500 is the regulatory standard for electrical connectivity in hazardous/explosive locations in the Americas that compiles to requirements according to the EN 60079 standard. Similarly, the ATEX Directive complies to the EN 60079 standard for the European market and the IECEx standard complies to the EN 60079 standard internationally.

 

 

 

 

 

 

 

 

Features

1. Metal locking levers require tools to open

Advantage: Does not allow opening of levers by hand

Benefit: Prevents opening levers/connector unintentionally in an explosive atmosphere 

2. Quick connect and disconnect

Advantage: Increased installation speed without special tools and improved safety and vibration-proof 

Benefit: Reduces maintenance downtime and troubleshooting compared to hardwiring alternative 

3. High density contact inserts

Advantage: Increased number of poles within a defined profile 

Benefit: Space saving - ability to place additional conductors per each connector

American Standards for Hazardous Locations

This hazardous connection interface is designed to meet the requirements for ignition protection under a Class 1 Div ll environment according to the American standard NEC 500 (National Electrical Code). This standard describes different areas of possible explosive atmospheres and complies to the EN 60079 standard for explosive location applications. The picture to the left shows an environment where different classes and divisions may reside. According to NEC 500 for Class 1 Div ll, the presence of flammable gas, vapor or dust, classifies a location as a Class 1 environment. Furthermore, Class 1 is subdivided into three divisions depending on the probability of flammable substance in the respective location sufficient enough to ignite with a spark. Division ll, in normal operation, is defined as an area with low probability of containing dangerous concentration of flammable substances and also contains the substance in a closed system.
