![]() ![]() This provides a greater margin of safety. Tip #3: It never hurts to choose one gauge larger, which means a lower AWG. The intersection between the selected row and column indicates the proper size of wire, in AWG or American Wire Gauge, you should use for the circuit. Choose a column that is equal to or greater than the maximum current draw of your light bar. The top row is the number of amps applied to the wire. The left column is the length of a wire, in feet. Below is a list of automotive wire sizes and their safe current ratings. So, you can easily choose the size of wire to feed it safely. Unlike water hoses, however, pushing excessive electrical current through a wire that is too small will melt the insulation or cause a fire.įortunately, you already know how much current your LED light bar requires. Many people make the analogy that electrical current through a wire is like water through a hose. Removing the positive terminal first risks you or a tool coming into contact with any metal connected to the negative terminal, which is most of the car. ![]() This greatly reduces the risk of shorting the battery, which is both exciting and very dangerous. Tip #2: Always remove the ground terminal clamp first followed by removing the positive side clamp. ![]() Your car or truck battery may appear dull and non-threatening, but it is a potentially life-threatening storehouse of electrons looking for any way out at the speed of light.īefore you start, disconnect the vehicle battery. ![]() Tip #1: Please do not skip over this section unless you have a great deal of experience with electrical wiring and components. Learning how to wire and LED light bar correctly ensures reliability and avoids unsafe operating conditions or damage to your vehicle. Once you have mechanically installed your new LED light bar, it is time to give it a steady supply of electrons so it has a steady supply of night vanquishing power. ![]()
