Hazardous Location Straight-Blade Plugs and Receptacles
Use connectors where ignitable gas and dust may be present. They are UL listed for Class I, Division 1 and 2, Groups C and D; Class II, Division 1 and 2, Groups F and G; and Class III hazardous environments.
Receptacles are compatible with both the NEMA 5-15 and 5-20 plugs.
Note: The current rating of your plug should not exceed that of your receptacle.

Hazardous Location Safe-Break Pin-and-Sleeve Connectors
Use connectors where ignitable gas and dust may be present, such as in refineries and silos. They are CSA certified for Class I, Division 2, Groups A, B, C, and D; and Class II, Division 2, Groups F and G. All have a chamber that withstands the pressure of an internal ignition—isolating it from spreading to the surrounding environment. They're rated IP66 and IP67 for protection from washdowns and temporary submersion.
Finger drawplates (sold separately) create a grip around plugs and sockets or receptacles, making it easier to pull them together tightly when mating.
Caps (sold separately) protect plugs when not in use.

Extension Cords for Hazardous Locations
Use these cords where ignitable gas and dust may be present. The industry designation is SEOOW, so the inner and outer insulation resists oil.
Hazardous location environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it is rated for your environment. See About Hazardous Location Environmental Ratings.
