Ancor Black 18 AWG 250ft Tinned Copper Wire

Eighteen gauge is the lightest wire in this group, and this black Ancor 18 AWG spool runs 250 ft. It suits low-current circuits like instrument lighting, sensors, and signal leads. Pair it with red 18 AWG for the positive side of each circuit.

Every strand is tinned to keep corrosion out, so connections stay clean and resistance stays low for years. The ultra-flexible Type 3 stranding makes small wire easy to route through tight chases and behind panels. It also resists breaking from vibration.

The vinyl jacket handles cold without cracking and resists fuel, oil, acid, salt water, and sunlight. Ratings are 600V, 105°C dry, and 75°C wet. It exceeds UL 1426, ABYC, and US Coast Guard charter boat standards. Browse more Marine Wire for heavier gauges.
