The specification “2-2-2-4” describes a type of aluminum electrical conductor commonly used for residential power distribution. The numbers indicate the American Wire Gauge (AWG) size of the individual conductors within the cable. In this configuration, three conductors are size 2 AWG, and one conductor is size 4 AWG. These cables are designed for direct burial, meaning they can be installed underground without requiring additional protective conduit in certain applications. Availability from a major retailer specializing in home improvement indicates accessibility for both professional electricians and homeowners undertaking electrical projects.
Employing aluminum conductors offers a cost-effective alternative to copper, especially in larger wire gauges where material costs are significant. The direct burial rating simplifies installation procedures by eliminating the need for conduit, reducing both material and labor expenses. Widespread availability through established retail channels ensures convenient access to this type of electrical wiring for a broad range of consumers and contractors. The specific gauge configuration is often utilized for supplying power to detached garages, workshops, or subpanels within a residential property.
