Conductive material Wire size to conduct 30 amps Wire size to run 50 amps Aluminum 0.1819 inches 0.2576 inches Copper 0.1443 inches 0.2043 inches Distance Needed To Be Covered For An RV Service To conduct 30 and 50 amps of current over 50 feet (15 meters), you need the following wire sizes. The Material Which The Wire Cable Is Made Fromĭifferent conducting materials used in wires have different resistances, and therefore the size of the wire used will depend on this factor.Īluminum wires have less conductivity (higher resistance) than copper wires. To ensure that you have a wire capable of managing the flow of electricity, consider the following variables. The smaller the gauge, the bigger the diameter is, and the greater the wires’ ability to transport bigger amperages. Strangely as the gauge of the wire increases, the diameter of the wire reduces. The diameter of the wire equals the gauge assigned by the AWG system. Knowing the correct wire size or gauge is key to making the right choice with any of these wire types.Ī wire is sized by the American Wire Gauge (AWG) system. When looking for the correct wire for your RV’s 30-amp or 50-amp system, you need to make the right choices. Each wire type is intended for a specific application.
If you’ve ever gone to the shops looking for electrical wire, you will know that there are a mind-bending number of wire types and sizes which you can choose from. Thus, using the correct wire size depending on the Voltage and amperage is crucial to avoid such accidents. The higher the circuit’s amperage rating, the larger the electrical cables you need to avoid excess heat that can melt wires and cause fires. Wires are rated for the voltages and amps that the wire can carry.Ī larger diameter wire can carry more current than a smaller one. Conclusion Why Does RV Wire Size Matter For An RV Service?.
