This full roll of green circuit wire delivers 100 yards (300 feet / 91.4 meters) of high-quality electrical conductor, designed for internal point-to-point chassis wiring, control panels, and general electronics prototyping. Housed on a durable spool for clean dispensing, this wire features a flexible conductive core insulated by a smooth plastic jacket, making it a staple material for engineers, hobbyists, panel builders, and technicians alike.

Specifications

• Length: 100 Yards (3000 feet / 91.4 meters)
• Conductor Type: Typically available in Stranded (high flexibility for motion) or Solid Core (holds its shape for breadboarding)
• Core Material: Tinned Copper or Pure Copper (provides excellent solderability and corrosion resistance)
• Insulation Material: PVC (Polyvinyl Chloride) or High-Temperature Silicone
• Voltage Rating: Typically 300V - 600V (Depending on standard certifications like UL1007 or UL1015)
• Temperature Range: -20℃ to 80℃ Up to 200℃ silicone variants)
• Color: Solid Green

Features

• High-Purity Copper Core: Tinned copper strands resist oxidation and prevent the wire from tarnishing when exposed to humidity, ensuring your solder joints remain chemically stable for years.
• Clean Spool Dispensing: Shipped on a heavy-duty plastic or cardboard spool wheel. This prevents tangles, kinks, and knots on your workbench, allowing you to pull and cut precise lengths smoothly.
• Easy Stripping Insulation: The outer PVC sheath is formulated to cut cleanly with standard wire strippers without tearing or tearing away the underlying metal conductor strands.
• Excellent Thermal Memory (Solid Variant): If selected in solid-core format, the wire bends smoothly into crisp 90℃ angles, making it perfect for layout routing across surface matrices.

Common Applications

• Control Panel Building: Wiring industrial relay bays, PLC terminals, and safety ground networks inside equipment enclosures.
• Breadboard Prototyping: Cutting custom-length jumper leads for microcontrollers like Arduino, Raspberry Pi, and ESP32.
• Custom Wire Harnesses: Wrapping and bundling specific multi-pin cable channels for automotive or robotics chassis arrays.
• Academic Labs: Outfitting engineering departments, school electronics kits, and Maker Spaces with baseline bulk wire stock.

Bench Tips for Best Results

• Match Current to Gauge: Never push more current through a thin wire than its AWG rating allows. Forcing 15A through a 24 AWG wire will cause the insulation to melt, short-circuit, and potentially catch fire.
• Use the Right Stripper Slot: Always match the wire gauge to the corresponding numbered indentation notch on your wire stripping tool. Using a slot that is too small will accidentally snip away outer copper strands, decreasing the wire's current capacity at that point.
• Pre-Tin Stranded Tips: If you are using the stranded variant and plan to insert the wire into a screw terminal block or solder it to a pad, twist the bare strands tightly together and apply a light glaze of solder (tinning) first. This stops individual threads from fraying outward and creating accidental short circuits with nearby components.
