GXL vs. TXL Primary Wire
Both GXL and TXL primary wire are insulated with high-temperature resistant cross-linked polyethylene. TXL, however, has thinner insulation and lower weight than its GXL counterpart. In practice, the thicker GXL is often used for engine compartment wiring while the thinner, more flexible TXL is used for everything else.
But in the end, there’s not much difference between TXL and GXL. With either wire, you’ll get the proven resilience, quality, and low cost that car enthusiasts need.
What size wire do you need?primary wire is designed for automotive circuitry
Choosing the correct size automotive primary wire depends on the acceptable voltage drop, length of the feeder/branch circuit conductor, load amperage, and the ambient temperature of the compartment where the wire will pass through (or originate from).
