"Engineered for superior conductivity and mechanical strength, this 8 AWG Stranded Bare Copper wire is a professional-grade solution for critical grounding and bonding. Featuring a flexible 7-strand, soft-drawn construction, it is designed for ease of installation in residential, commercial, and industrial electrical systems."
This conductor is the industry go-to for grounding electrical services and bonding specialized equipment. Its 7-strand design offers a significant advantage over solid wire when pulling through conduit, providing the flexibility needed for tight bends without sacrificing the high ampacity required for safety.
Maximum Conductivity: High-purity copper provides a low-impedance path to ground, essential for safety and surge protection.
Soft-Drawn Flexibility: Annealed for easier handling, reducing installer fatigue and "spring-back."
Rugged 7-Strand Build: Provides more surface area for grounding clamps while remaining durable enough for direct burial.
Code-Compliant Grounding: A standard choice for service entrance grounding and equipment bonding grids.
Weather & Soil Resistant: Naturally stands up to moisture and soil chemistry for reliable long-term performance.
Conductor Size: 8 AWG
Construction: 7-Strand
Temper: Soft-Drawn (Annealed)
Material: Bare Copper (Uninsulated)
Overall Diameter: 0.146 inches
Approx. Weight: 51 lbs per 1,000 ft
Standards: ASTM B-3 (Soft/Annealed), ASTM B-8 (Concentric-Lay-Stranded)
Structural Bonding: Frequently used for bonding grids in swimming pools and outdoor structures.
Service Grounding: Connects the main electrical panel to the grounding electrode system (ground rods).
Industrial Equipment: Ideal for grounding motors, transformers, and heavy machinery.
Lightning Protection: Used in buried grounding loops and down-conductors for lightning surge protection.
Technical Note: All values are nominal and subject to industry tolerances and manufacturer corrections. Specifications are subject to change without notice. It is the buyer’s responsibility to verify that all materials meet the specific requirements of the project and comply with local electrical codes.

Yes. 8 gauge bare copper is frequently used for grounding residential electrical services and bonding metal water piping or structural steel. It is a standard choice for connecting a service panel to a grounding electrode (ground rod) in many residential configurations, though you should always verify specific local code requirements regarding conductor sizing for your service entrance.
The primary advantage is flexibility. While solid 8 AWG can be very stiff and difficult to manipulate, the stranded construction allows the wire to be easily pulled through conduit and bent around tight corners without kinking or breaking. Additionally, stranded wire performs better in environments with physical vibration, as it is more resistant to fatigue than solid copper.
Absolutely. 8 AWG bare copper is the industry standard for pool bonding. It is used to create an equipotential bonding grid around the pool, connecting the pump motor, heater, and any metallic structural components to ensure there is no dangerous voltage difference between them.
You should choose Tinned Copper if your project is in a high-corrosion environment, such as near the ocean (salt air) or in industrial areas with heavy chemical exposure. Tinned copper has a microscopic layer of tin that prevents the copper from oxidizing and turning green. For standard residential grounding, interior electrical panels, or dry-soil burial, 8 AWG Bare Copper is the industry standard and more cost-effective. However, for marine use or if you plan on soldering your connections, Tinned is the superior choice.
Yes. 8 AWG (American Wire Gauge) is the technical term, while 8 gauge is the common name. Both refer to the same diameter and electrical capacity.
Yes. According to NEC Table 250.122, an 8 AWG copper conductor is typically the minimum size required for a grounding conductor on circuits protected by a 40-amp to 100-amp overcurrent device (depending on the specific application). Because this wire is 7-strand, it provides excellent surface area contact for grounding lugs, ensuring a safe trip path for your breakers in the event of a fault.
Note: Always consult with a certified local electrician who is up to date on all local codes before purchasing.
