Automotive Primary Wire Ampacity

Choosing the correct gauge automotive 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 primary wire will pass through.

Automotive primary wire ampacity.

Gxl wire is a specific type of wiring that is used for automotive primary wiring. More current draw higher amperage requires a larger wire gauge to safely power the accessory. Made is the usa our automotive wire is wrapped in a thermoplastic pvc insulation is smooth for pulling through wire loom and conduit tough enough to resist grease oil and acid and has a temperature rating of 176 f 80 c. Outside engine compartments the ambient temperature should generally be 20 c.

Automotive voltage is not 12 volts. Standard automotive primary wire is 18 gauge. This typically allows for a 10 15 variance in draw so the window motor only draws roughly 20 amps. The floodlights draw 15 amps of current.

This is good for signal wires but not for hi current applications. 50v gxl automotive. The actual resting voltage of a fully charged 6 cell automotive lead acid battery is about 12 7 volts or about 2 1 volts per cell. Automotive wiring is not exactly 12 volt.

Our gxl wire has thin walls along with a single conductor to make it one of the thinner primary wiring solutions that is great for automotive applications. For example you want to add some flood lights to your vehicle. The bare copper wire conductor is wrapped with cross linked polyethylene and allows for 50 volts. 6 4 volts for a 6 volt lead acid battery.

Whether your vehicle is a ford or a ferrari our automotive wire is the optimum choice for 12 volt and 24 volt dc electrical systems.
