The Southwire Company LLC 56422033 is a 16-gauge primary wire in a 24-foot length, finished in green insulation. Primary wire of this type carries low-voltage DC current in automotive, trailer, marine, and equipment wiring applications. At 16 AWG, it handles moderate current loads suited to lighting circuits, accessory feeds, and control wiring runs. The green color coding supports polarity and circuit identification on the job. Each card contains a 24-foot coil, making it a practical stock item for service vans and shop use. Licensed electricians, HVAC technicians, and equipment installers routinely keep primary wire on hand for control wiring and accessory circuit work.
This wire is packaged on a card and sold individually. It is well-suited for residential and light commercial wiring tasks where a short, pre-measured run of 16 AWG primary wire is needed. Typical applications include trailer wiring, small equipment harnesses, panel accessory feeds, and low-voltage control circuit repairs. The 24-foot length covers most single-circuit runs without splicing. Package quantity is 6 cards per case, making it easy to stock multiples for ongoing service work.
Designed as a general-purpose primary wire suitable for low-voltage DC wiring applications including automotive, trailer, marine, and light equipment harness work.
Primary wire installation should follow applicable NEC guidelines for the circuit type and environment. Disconnect or de-energize the circuit before stripping, terminating, or splicing any wire. Use the correct gauge wire strippers and crimp terminals rated for 16 AWG conductors. Avoid routing primary wire near sharp edges or heat sources without appropriate protective sleeving.
