1 Gauge Battery Cable Size 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.

1 gauge battery cable size chart. 4 0 364 30 simply refers to a 4 awg cable made with 364 strands of 30 awg wire. 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. So all interconnecting cables are 2 0 based on the chart below. D intersect current in amps with length in feet to identify the wire size.

Find the current consumption of the load on the horizontal axis of the chart. Click the image below to enlarge. Battery wire size per voltage amperage load and length chart below shows minimum cable size to use awg wire. Actually for my current installation i ve sized all of my dc cables to meet the 175 amp worst case scenario.

The reason this sizing is used is because wire sized using the sae wire gauge have larger and fewer strands than those sized using the standard american wire gauge. D n in 0 005 in 92 36 n 39. Voltage system allowing a 20 voltage drop. The n gauge wire diameter d n in millimeters mm is equal to 0 127mm times 92 raised to the power of 36 minus gauge.

American wire gauge size calculator and chart. See adjacent charts 25 coils 100 coils or oem reels length depends on awg please consult a sales representative for 80 1434 03082reel dimensions battery cable load charts length to load these charts will show length in feet. The fine stranded wire will pass more amperage than course stranded wire that has a lower strand count. They don t really understand why it s better.

Sae wire gauge size and amperage for a d c. 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. 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. A windlass rated 80a is 25 from the battery.

Now lets say that you are using a smaller gauge cable for that same length and your voltage drop is 10. A size of 4 0 364 30 indicates the gauge size as well as the strand count. 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. The following maximum amps versus cable size awg come from the nec version 2011.

Circuit length is 50 circuit type is non critical and correct wire size is 4 awg. The wire size listed in the graph at the intersection denotes the gauge of wire to use. 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.
