The EPEXC-4X-12.3-100 explosion-proof extension cord from Larson Electronics is designed to extend the reach of equipment in hazardous locations where power receptacles are not in close proximity to the work space. The explosion-proof extension cord is built with 100 feet of 12/3 SOOW explosion-proof cord that is rated at 20 amps of continuous service, providing ample length for moving about the work space. This cord is fitted with four explosion-proof twist lock receptacles constructed of non-sparking aluminum for connection of equipment in hazardous locations. A 20-amp explosion-proof plug is terminated at the end of the 100-foot cord to provide power to the four outlets. This cord, and its plug and receptacles are a 3-pole, 2-wire design, which works with most common explosion-proof equipment. This explosion-proof extension cord is Class 1 Division 1 Groups C, D and Class 2 Division 1 Groups E, F, and G rated, making it ideal for use in hazardous locations where flammable gases and vapors are present. The cord is oil, chemical and abrasion resistant for durability and the receptacles feature deep recessed contacts for protection against arcing and a powder coat finish for resistance to corrosion. This cord is perfect for connecting explosion-proof lighting, fans and blowers, and extending the range of portable power supplies and substations within the hazardous work area.
