Top Definition

A hollow, metal, flexible conduit system made of either steel or aluminum. Wires are pulled through them in accordance with NEC 350, 430-123, 502-4, 503-3, 517-30, 645-5. You find this used most often for fixture whips, motor attachments to safety switches, and other short run connections where a flexible system is more suitable than a rigid pipe system.
