"Designed for high-conductivity grounding and bonding, this 2 AWG Stranded Bare Copper wire is engineered for peak performance. Featuring soft-drawn (annealed) construction, it provides the perfect balance of flexibility and strength, making it a reliable solution for residential, commercial, and industrial grounding systems."
As electrical infrastructure scales up, so does the demand for a low-impedance path to ground. This 2-gauge conductor is the industry standard for grounding major service equipment and creating comprehensive grounding rings. Its stranded design is essential at this thickness, offering a significant labor advantage over solid wire by allowing for manageable bends and superior contact within high-torque grounding lugs.
Massive Fault-Current Capacity: 99.9% pure copper ensures maximum safety for high-voltage and high-amperage systems.
Installer-Friendly Annealing: Heat-treated to be as pliable as possible, reducing the "spring-back" common in large-gauge conductors.
Heavy-Duty 7-Strand Build: Optimized for mechanical durability in direct-burial trenches and heavy-wall conduit.
Oxidation Resistance: Naturally resilient against soil chemicals, ensuring a long-term, reliable connection to earth.
Commercial Code Compliance: Meets strict NEC requirements for grounding electrode conductors in large residential and industrial services.

#2 AWG bare copper wire is the industry standard for residential and light commercial electrical grounding systems.
Main Panel to Ground Rods: Connects the main service panel to the ground rods outside the house.
Commercial Grounding Grids: Used to bond steel structures and equipment in warehouses and retail spaces.
Lightning Protection: Serving as the main down-lead conductor to safely carry lightning strikes from a roof-mounted rod to the earth.
Data Centers: Providing a low-impedance ground to protect sensitive servers from static and surges.
Solar Farm Infrastructure: Grounding mounting racks and frames for large-scale photovoltaic arrays.
The OD of #2 bare copper wire is 0.292 inches
While both solid and stranded copper have the exact same electrical capacity, stranded wire is highly preferred by installers for its flexibility. Solid copper wire in larger gauges is incredibly rigid and behaves like a stiff metal rod in the field. Stranded wire allows installation crews to easily manipulate the conductor, bend it around foundation walls, and cleanly transition it into service panels without kinking or fighting the metal.
Yes. 2 AWG is the standard minimum size for a "Ground Ring" that encircles a building or structure. Its heavy gauge and stranded construction make it ideal for direct burial in a trench around the perimeter of a facility to provide a low-impedance path to earth for lightning and surge protection.
Yes. 2 AWG is a popular choice for concrete-encased electrodes (Ufer grounds). Its high purity and corrosion resistance ensure a permanent, high-quality connection between the building's rebar and the main electrical service.
Yes, our 2 AWG stranded bare copper is manufactured to meet ASTM B-3 (for soft or annealed copper) and ASTM B-8 (for concentric-lay-stranded conductors). This ensures it meets all professional requirements for conductivity, tensile strength, and structural integrity.
While standard 2 AWG Bare Copper is the go-to for most grounding jobs, Tinned Copper is recommended for "extreme" environments. If your project is located in a high-salt coastal area, a wastewater treatment plant, or an area with highly acidic soil, the tin coating will prevent the copper from oxidizing (turning green) and ensure the connections remain highly conductive for decades.
You should use a clamp specifically rated for #2 AWG. If the connection is being made underground or to a ground rod, ensure the clamp is UL listed for Direct Burial (marked "DB") to prevent galvanic corrosion over time.
