THE ESSENTIAL CONDUCTOR FOR 20-AMP CIRCUITS
This listing offers a single, factory-fresh, and unopened 500-foot spool of 12 AWG (American Wire Gauge) Stranded Bare Copper Electrical Wire. This premium conductor is the gold standard for all high-quality electrical installations requiring a 20-amp circuit, providing superior conductivity and ease of use for electricians, contractors, and advanced DIY enthusiasts.
The wire features a tough dual-rated THHN/THWN-2 insulation/jacket system, making it suitable for virtually any interior or exterior application within a conduit system. The stranded construction, which typically includes 19 fine copper strands, dramatically enhances flexibility compared to solid wire, ensuring a faster, smoother, and less labor-intensive pull through electrical conduit and easier termination within panels and junction boxes.
Invest in quality and compliance. This wire meets or exceeds all current UL standards and NEC requirements for safe, long-term electrical performance.

Current Carrying Capacity (Ampacity)
Under normal conditions, 12 AWG copper wire is sized to protect the circuit up to a 20-amp breaker.
* Max Ampacity (75^{\circ}\text{C} Column): 25 Amps
* Max Ampacity (90^{\circ}\text{C} Column): 30 Amps
Note: While the wire is rated for 30 Amps at 90^{\circ}\text{C}, the NEC often restricts branch circuit breakers (like those in homes and offices) to the 20-Amp limit to protect the connected equipment.
WHY CHOOSE STRANDED 12 AWG?
The decision to use stranded wire over solid core wire is crucial for professional installation quality:
* Ease of Installation: The inherent flexibility dramatically reduces the physical effort required when pulling long runs or multiple conductors through rigid or flexible conduit, saving valuable installation time and preventing jacket damage.
* Longevity and Durability: Stranded conductors are far more resistant to metal fatigue and breakage caused by repeated bending or system vibration (common around large machinery, HVAC units, or motors).
* Superior Termination: While solid wire is easier to terminate with standard screws, the flexibility of stranded wire allows for superior, tighter packing and neat routing inside electrical panels, ensuring better long-term connections when using appropriate wire connectors (e.g., ferrules, split bolts, or pressure terminals).
IDEAL APPLICATIONS
This large spool is essential for the following major electrical projects:
* New Construction & Major Renovations: Full-scale wiring of electrical panels to feed numerous 20-amp branch circuits throughout a building.
* Dedicated Circuits: Installing dedicated lines for high-power devices such as appliances (microwaves, dishwashers), large computer equipment, servers, or workshop tools.
* Outdoor & Wet Installations: Perfect for lighting or power circuits in garages, basements, or outdoor runs when installed in appropriate conduit (THWN-2 rated for wet locations).
* Commercial Lighting & Power: Running power to commercial-grade lighting systems and heavy-duty receptacles in offices, retail, or industrial settings.
SALE AND SHIPPING INFORMATION
