Select a cable with thickness that will meet expected level of resistance. Percentage volt drop= % of volt drop that is acceptable for the circuit. VDI=AMPS by FEET dived by PERCENTAGE VOLT DROP by VOLTAGE Voltage drops when current pass through a conductor. The resistance is inversely proportional to the cable’s diameter and directly proportional to length. It is important to get the properties right before selecting a cable.Ĭables have amount of resistance. These materials have different properties for various purposes. Others are made of tinned copper cable and double insulated cable. Thin wall have less wall thickness insulation unlike a standard PVC insulation. Furthermore, choose a cable that has additional capacity.Ĭables exist in different materials. Therefore, you can use a cable with a rating of 4.17A or above. As an example, we have a power rating of 50W, use the equation of I=P/V, the current drawn will be 50W/12V=4.17A. Despite the cable has fuses in the circuit to offer protection, it should not over- heat. If not, the power supply will catch fire. The cable should carry the expected current and safety margin. Make sure the cable is not too large because it can cause problems.Įvery appliance linked to circuit has a current draw back that is connected with the operation. However, the voltage drop will not be useful like the one resisted along a bulb. Similarly, Copper conductor will also convert energy conducted.

For example, a bulb will change electrical energy to light and heat. For this reason, energy will be lost as voltage drop got from the length of cable. Battery cable size is based on length cable and amperage.ġ AWG handles 200amps at length of 9.4feet, use 1 gauge cable.ĢAWG has 150amps at 10feet, use 2 gauge cable.ĤAWG has 100amps at 9.4feet, use 4 gauge cable.ĦAWG has 50amps at 11.8feet, use 6 gauge cable.ģ/0 AWG battery cable has 300amps at 5 feet.Ĥ/0 AWG battery cable has 600amps at 9 feet.Īll electrical circuit including cables has resistance.

For instance, a vehicle will alert the driver in case a problem has occurred hence needs to be serviced. You should always monitor the cables to determine any fault.

Even though their build and operation are simple, they can result in problems in the device. Cables are made of strong gauge wire and insulation because of high flowing current. They connect the battery to the device to allow the flow of current.

Battery cables are essential to any electrical system.
