In stage lighting, a multicable (otherwise known as multi-core cable or mult) is a type of heavy-duty electrical cable used in theaters to power lights. The basic construction involves a bundle of individual conduc ...
. They are wired with six hot/live pins, six neutral pins, six ground/earth pins, and a final central pin used to aid alignment of the male end of the connector with a female receptacle. The Socapex was first created by a company called Socapex in 1961, which later on became Amphenol Socapex. "Socapex" became a brand name owned by Amphenol Socapex, the term "Soca" is now often applied to similar off-brand connectors as a
genericized trademark.
"Breakouts" are often used to connect fixtures to the cable. The breakout consists of a male Socapex connector with six "tails" with female
parallel blade receptacle,

Some fixtures and assemblies containing several lamps, such as
PARbars, may use a panel mounted Socapex connector to avoid the need for a separate breakout, and many such fixtures also incorporate a female Socapex connector to allow further similar fixtures to be chained from the same supply.
Amphenol Socapex is still manufacturing and selling the original Socapex. These connectors are keyed to prevent insertion into a circuit with the wrong voltage, or to prevent insertion of audio cables on power circuits.
