"Designed for heavy-duty grounding, bonding, and primary power distribution, this 2/0 AWG Stranded Bare Copper wire is engineered for high-capacity electrical performance. Featuring a high-flexibility 19-strand construction, it provides the ideal combination of pliability and physical mass, making it a reliable solution for utility, industrial, and commercial grounding systems."
This conductor is a primary choice for substation grounding grids, heavy commercial buildings, industrial processing plants, and robust lightning protection systems. Moving up to the 2/0 gauge provides a massive increase in cross-sectional mass over smaller wires, ensuring a safer, ultra-low-impedance path to ground for critical infrastructure. Its premium 19-strand design ensures highly manageable installation and smoother bending in the field, while the high-purity copper guarantees an unmatched structural lifespan.
High Conductivity: 99.9% pure copper provides a massive, low-impedance path to ground to clear high-magnitude fault currents safely.
Soft-Drawn & Annealed: Combined with the 19-strand layout, the thermal annealing process ensures the wire remains highly flexible for wrap-arounds, routing through tight trenches, and pulling through conduit.
High-Flexibility 19-Strand Construction: Utilizing 19 individual interwoven strands rather than the rigid 7-strand alternative drastically improves bendability without sacrificing cross-sectional area or tensile integrity.
Environmental Resilience: Bare copper offers natural, long-term resistance to galvanic corrosion in soil and concrete without requiring a protective jacket.

2/0 bare copper wire is commonly used for commercial and industrial grounding systems. It is the go-to standard for grounding grids, electrical substations, lightning protection down-conductors, and bonding heavy equipment or structural steel to the earth.
The main difference is flexibility. Solid bare copper is a single, stiff strand of wire that holds its shape well, making it ideal for permanent overhead runs or direct burial applications where movement is not required. Stranded bare copper is made of multiple smaller wires twisted together. This makes it highly flexible, much easier to pull through tight conduit runs, and highly resistant to vibration or mechanical fatigue.
Yes. Bare copper is naturally highly resistant to soil corrosion, allowing it to be directly buried in trenches or concrete slabs without any protective insulation or conduit. This is standard practice for creating "ground rings" or connecting grounding electrodes (ground rods) to a main service panel.
Note: While copper resists most soil conditions, always check local codes if you are dealing with highly acidic or chemically treated soils.
If you are routing a single 2/0 bare copper grounding wire through a protective conduit, a 1-inch conduit (PVC or Rigid Metal) is standard and offers plenty of fill room for an easy pull. Always consult NEC Chapter 9, Table 4 for specific fill-capacity limitations if routing it alongside phase conductors.
The temper refers to how malleable or stiff the metal is.
The nominal outside diameter (OD) of 2/0 stranded bare copper is 0.418 inches (10.62 mm).
Absolutely. Our 2/0 stranded bare copper is made of soft-drawn, high-conductivity copper that is perfectly suited for exothermic welding, mechanical ground clamps, and compression lugs. It provides a permanent, low-resistance connection that won't degrade underground.
