A correctly designed and installed wiring system is crucial to the safety and reliability of any vehicle. The correct size and type of cables and terminals must be used to interconnect the components. Most cables are made up of thin strands of cop- per. Cables sizes are denoted the number of strands and the individual strand thickness. E.g. 14/030 cable has 14 strands of wire each 0.3mm diameter. This cable will safely carry a continuous current of 5.75 amps. 28/030 –17.5 amps, 44/030— 25.5 amps etc. Use the cable sizes listed in the wiring schedule only as a guide. If, for example, you are using high wattage headlight bulbs or powerful HiFi equipment then increase cable sizes accordingly. To calculate current (amps) drawn by a component simply divide the wattage by the voltage. For instance, a 100 watt headlight bulb will draw 100/12 = 8.3 amps.
