An 18-foot Socapex fanout cable is a specialized breakout assembly designed to bridge the gap between a multi-circuit power distribution system and individual lighting fixtures or devices. It functions as an adapter, consolidating multiple independent electrical paths into a single, manageable connection point. On one end, it features a single male or female 19-pin Socapex connector, which plugs into a dimmer rack, power distribution panel, or another Socapex cable run. The other end terminates in a cluster of individual, labeled connectors—most commonly Edison-style (NEMA 5-15) plugs, Stage Pin (Bates) connectors, or PowerCON—each corresponding to a specific pin or pair of pins within the Socapex standard. This design allows a single, thick multi-core cable to be efficiently fanned out into several standard power cords for individual fixtures.

The construction of this cable is critical for safety and performance, utilizing heavy-gauge, color-coded internal wiring that is precisely mapped from the Socapex pins to the correct output connectors. This precise pinout mapping follows established industry standards to ensure that each circuit is correctly identified and delivers the intended dimmer channel or non-dim power to its designated fixture. The 18-foot length provides a practical amount of flexibility for routing from a central power drop to a cluster of nearby lights, reducing cable clutter and eliminating the need for multiple individual extension cords from a distant source. The cable jacket and individual fanout legs are built to withstand the physical rigors of touring and stage use, offering resistance to abrasion, crushing, and heat.

In practice, this cable is an indispensable tool for lighting technicians and production electricians, dramatically speeding up the wiring process for lighting rigs. It enables clean, organized power distribution from a Socapex-based system to conventional fixtures, making it a standard piece of equipment in theater, television studios, concert touring, and corporate event production. By using a fanout, technicians can ensure consistent and reliable connections, simplify troubleshooting, and maintain a safer work environment by reducing trip hazards and clearly organizing circuit assignments. Its specific length of 18 feet is often chosen to offer sufficient reach while remaining manageable for coiling, transport, and storage.
