Single-pole plugs and connectors attach to the ends of cables to supply or extend temporary power in high-current and industrial applications where larger or multi-conductor cables would get in the way or be impractical. Plugs have terminals that insert into single-pole connectors and receptacles, and connectors have receptacles that accept single-pole plugs. Typical uses include running power to and from portable machinery, generator docking stations, stage and studio equipment, and carnival rides.
