SKU: SMA-141-166F 16 Gauge Blue Primary Wire - 20 Foot Length for Agricultural Equipment Electrical Systems

Whether you're rewiring work lights on your combine or fixing trailer connections, 16 gauge primary wire is basic wire for autos, trucks and numerous other wiring projects. This blue wire gives you 20 feet to work with—enough for most repair jobs without having too much left over. When electrical gremlins start acting up, having quality wire on hand gets you back to work fast.

What You're Getting

• 16 AWG stranded copper wire that's flexible enough to route through tight spaces but tough enough to handle the current
• Vividly colored vinyl insulation on flexible stranded copper so you can easily identify circuits later
• Smooth surface wire that pulls through conduit, loom, and protective tubing without snagging
• GPT-rated insulation that handles extreme temperatures without cracking or becoming brittle
• Oil, grease, and acid resistant coating—because farm equipment sees it all

Built for Real Farm Work

This wire handles the electrical needs of tractors, combines, implements, and other agricultural equipment. The 16 gauge size is perfect for lighting circuits, auxiliary power feeds, and control wiring—basically anything that doesn't need heavy-duty battery cables. It's the same quality wire you'll find in original equipment harnesses.

Made to Last

Farm equipment electrical systems take a beating from vibration, moisture, chemicals, and temperature extremes. This wire's GPT insulation stays flexible in cold weather and won't crack from heat or UV exposure. The stranded copper core resists breakage from constant flexing and vibration.

Installation Notes

Always use proper gauge wire for your application—16 gauge handles up to about 22 amps safely. When splicing, use quality connectors and heat shrink tubing for connections that'll last. A quick tip: leave yourself a little extra length when routing wire—it's easier to trim than to splice in more later.
