Electronix Express 18 Gauge Stranded Hookup Wire Black 100 Feet

18 Gauge Stranded Hookup Wire

This 18 gauge stranded tinned copper wire suits hobbyists, students and technicians building low-voltage circuits, breadboard prototypes or automotive accessory looms. The flexible stranded construction eases routing through tight chassis channels and around corners. Black insulation provides simple visual identification in multi-wire harnesses.

Practical limits of 18 gauge hookup wire

At 18 gauge the conductor handles only modest current, making it unsuitable for high-power distribution or starter-motor cables. Voltage drop becomes noticeable on longer runs, so keep individual circuit lengths short. The insulation is rated for general-purpose low-voltage use and not for mains-voltage or high-temperature engine-bay exposure.

Capacity and headroom for 100 foot spool

One hundred feet supplies enough length for several small projects or a complete vehicle accessory rewire with wire left over for future repairs. The spool covers typical dashboard lighting, sensor leads and radio power feeds without joining multiple shorter pieces. Large-gauge power feeds, battery cables or inverter inputs will require heavier conductor stock.
