The Southwire 55668333 is a 24-foot length of 16-gauge yellow primary wire designed for low-voltage automotive, marine, and general-purpose electrical wiring applications. This single-conductor wire is sold on a card and is suited for use in circuits requiring a flexible, color-coded conductor. The 16-gauge sizing handles typical accessory and lighting loads found in mobile and equipment wiring. The yellow jacket provides fast visual identification in multi-wire harness runs, reducing the chance of tracing errors during installation or service.
This primary wire is used in automotive electrical repairs, trailer wiring, marine accessory hookups, and general equipment wiring where a short, pre-cut length is needed. Electricians, auto technicians, and equipment service techs reach for carded primary wire when replacing damaged sections of wiring or adding circuits to vehicles and machinery. The 24-foot length covers most single-run repair and add-on jobs without waste.
Designed as a general-purpose primary wire replacement and add-on conductor for automotive, marine, and equipment electrical systems requiring 16-gauge wiring.
Installation is typically performed by auto technicians, marine electricians, or equipment service professionals. Disconnect the battery or power source before splicing or connecting any wiring to avoid shorts or accidental circuit activation. Use appropriately rated connectors, terminals, and heat shrink or electrical tape to secure all connections. Follow applicable wiring codes and manufacturer guidelines for the specific vehicle or equipment being serviced.
