Ancor Brown 18 AWG Tinned Copper Wire - 500'

Ancor Brown 18 AWG Tinned Copper Wire - 500' is the marine electrician's go-to choice for permanent boat wiring installations, engine harnesses, and bilge pump circuits. After years on the water, any experienced boater knows that saltwater corrosion destroys inferior wire faster than a storm surge. This bulk spool delivers the reliability demanded by U.S. Coast Guard charter boat standards and ABYC specifications, making it the foundation of safe, code-compliant marine electrical systems.

The tinned copper construction resists oxidation and corrosion far better than bare copper, a critical advantage in the harsh marine environment where moisture and salt spray are constant threats. The 18 AWG gauge provides sufficient ampacity for moderate loads—lighting circuits, instrument clusters, accessory switches, and low-draw solenoids—while the premium vinyl insulation is rated to 600V and exceeds UL 1426 and CFR Title 46 standards. The 500-foot length (approximately 5.5 lbs per spool) allows installation across large vessels without excessive splices, reducing potential failure points and voltage drop across longer runs.

Both DIY boaters upgrading navigation systems and professional marine electricians rely on Ancor marine-grade wire for permanent installations where longevity and code compliance cannot be compromised. The brown insulation helps distinguish auxiliary circuits from standard black and red power/ground lines, simplifying troubleshooting and future maintenance. This product is compatible with standard crimp terminals, solder lugs, and panel connectors; install it with marine-rated inline fuses and breakers sized appropriately for the 18 AWG ampacity to ensure full system safety and longevity in saltwater service.
