Battery Cable Gauge Diameter Chart
Find the length of the circuit on the vertical axis of the chart noting that the length is the round trip distance from the panel or battery to the load and back.
Battery cable gauge diameter chart. American wire gauge size calculator and chart. The wire size listed in the graph at the intersection denotes the gauge of wire to use. The n gauge wire diameter d n in inches in is equal to 0 005in times 92 raised to the power of 36 minus gauge number n divided by 39. 4 0 364 30 simply refers to a 4 awg cable made with 364 strands of 30 awg wire.
Wire gauge calculations wire diameter calculations. Battery cable is used to power your electrical system and is sized according to the american wire gauge or awg for short specification for electrically conductive cables. Sae wire gauge size and amperage for a d c. Strands x sbc inches mm inches mm color put up.
They don t really understand why it s better. Now lets say that you are using a smaller gauge cable for that same length and your voltage drop is 10. Voltage system allowing a 20 voltage drop. 18 gauge wire awg 7 3 ft.
A size of 4 0 364 30 indicates the gauge size as well as the strand count. Welding cable tends to be large gauge wire so i think the guys that claim welding cable is the very best stuff to use do so because they are comparing very large 2 0 welding cable to a small 2 gauge battery cable. Find the current consumption of the load on the horizontal axis of the chart. Now your voltmeter at the other end of your battery cable will read 10 8 volts 12 volts 10 and that same 100 amp current draw will cause your battery cable to absorb 120 watts 10 amps of power leaving only 90 amps available.
D n in 0 005 in 92 36 n 39. Spartan power 2 foot 1 0 awg 0 gauge battery cable set made in america many wire lengths to choose from 2 foot 3 8 ring terminals 4 8 out of 5 stars 62 34 00 34. Our battery cable is american made and comes in gauge awg sizes of 6 4 2 1 1 0 2 0 3 0 and 4 0 with 6 gauge being the smallest and 4 0 gauge being the largest. Battery cable load charts length to load these charts will show length in feet.
Automotive wire amperage capacity chart recommended length and amperage for automotive wire while maintaining a 2 or less voltage drop at 12 volts automotive wire size 5 amps 10 amps 15 amps 20 amps 25 amps 30 amps 20 gauge wire awg 4 5 ft 2 2 ft 1 6 ft.
