Multicable
In stage lighting, a multicable is a type of heavy-duty electrical cable used in theaters to power lights. The basic construction involves a bundle of individual conductors surrounded by a single outer jacket. Whereas single cables only have three conductors, multicable has ten or more. They are configured to run in six or eight-circuit varieties. Typically, both ends of multicable have a specific connector known as a Socapex Connector. Technicians then combine the cables with break-outs and break-ins, which essentially are an octopus-like adapter with one Socapex end and six to eight Edison, twist-lok, or stage pin style connectors.
Use
Multicable is used when technicians need to mount lights where no permanent circuiting options exist. Typically, mounting pipes designed for lighting use have enclosed raceways with permanent power outlets, running to a remote dimmer unit somewhere in the theater. When such options are not available, technicians have to run cable to these positions instead. In traveling lighting installations or tours, prerig lighting trusses like the GT PLUS system from Tyler Truss systems are pre-built with lighting fixtures, data distribution, and cables aside from primary power delivery.Specific methods of usage
Originally, running cable to trussing had to be done with cable bundles, running single extension cords long distances and tying or taping them into groups, or just running cable in a disorganized mess. Loose multicable is commonly used in 'one-off' shows. This method often includes labeling but not bundling multiple cables that are routed to the same truss. Instead, several circuits can be run in a single cable, using multicables. These are used most often in theaters without on-stage raceways or in systems with portable dimming racks, which are not wired into the building. Multicable is a quick, organized way of getting a large amount of circuits away from the dimmers to the lights.Cable bundling is a practice that involves taping multiple cables together for convenience during load-in and load-out. These bundles may also include motor cables for chain motors, data cables, network cables for cameras or lighting data, and more. Various methods are used to build these bundles including ceiling-mounted empty cable drums similar to cable reels, as well as custom solutions like Christie Lites' Cable Bundling Assembly. This practice is common for tours, large productions,
