12 Gauge Cross-Linked SXL Wire. is a higher performance automotive wire typically used for 20 amp circuits in a standard automotive circuit. The actual amperage that 12 gauge wire can handle depends on the length of the wire. SXL wire has a PVC insulation that has undergone a process that chemically alters the molecules of the insulation - cross-linking - which provides superior resistance to abrasion, moisture, oil, grease, gasoline, and other solvents. Works well in engine compartments. Rated to 60 volts DC or 25 volts AC. The temperature rating of SXL wire is -40°F to 257°F (-40°C to 125°C). The inside stranded core of the wire typically consists of 19 Strands of 25 gauge pure copper. With the insulation coating the wire, the nominal outside diameter is 0.161''. Made in the USA and RoHS compliant.
