Southwire Building Wire 10GA Black 100 22973284

The Southwire 22973284 is 10 gauge black building wire supplied in a 100 foot length for branch circuit and equipment feeder wiring.

Ten gauge copper conductor is rated for 30 amps in standard building applications, making it a common choice for air conditioning condensing unit circuits, electric water heaters, dryer circuits, larger motor loads, and equipment subfeeds. Conductor selection must follow the equipment nameplate minimum circuit ampacity and be coordinated with the maximum overcurrent protective device rating.

Black identifies an ungrounded conductor by convention, typically the first phase in a multi-conductor run. Maintaining consistent colour coding across an installation allows a technician arriving later to identify conductor function without tracing, which reduces both service time and the risk of misconnection.

Ten gauge is also selected on longer runs at lower amperage to limit voltage drop. This is a genuine consideration for HVAC equipment: a compressor operating at reduced terminal voltage draws higher current, runs hotter, and suffers shortened winding and contactor life. On long runs to detached garages, rooftop units, or remote equipment, upsizing the conductor is often the correct call even where the ampacity table permits smaller wire.

Applications include condensing unit and heat pump branch circuits, disconnect switch feeds, electric heat circuits, subpanel feeders, and general commercial and residential distribution.

Confirm insulation type and temperature rating suit the installation environment and terminations, apply required derating for conduit fill and ambient temperature, and verify compliance with applicable electrical code.
