Automotive Primary Wire Ampacity

Automotive voltage is not 12 volts.

Automotive primary wire ampacity.

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. Automotive wiring is not exactly 12 volt. 50v gxl automotive. Gxl wire is a specific type of wiring that is used for automotive primary wiring.

This is good for signal wires but not for hi current applications. 6 4 volts for a 6 volt lead acid battery. This typically allows for a 10 15 variance in draw so the window motor only draws roughly 20 amps. During another project you pinched the wire in the door and now you have to replace it.

The floodlights draw 15 amps of current. 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. 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. 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.

Standard automotive primary wire is 18 gauge. Wire amperage capacity chart in order for your automotive electrical system to perform properly your wire must be sized properly based on the amount of current amperage the wire must carry and the length that the wire needs to be. For example you want to add some flood lights to your vehicle. Primary hook up wire.

Outside engine compartments the ambient temperature should generally be 20 c.
