1 Gauge Battery Cable Size Chart

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.

1 gauge battery cable size 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. American wire gauge size calculator and chart. A windlass rated 80a is 25 from the battery. 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.

Actually for my current installation i ve sized all of my dc cables to meet the 175 amp worst case scenario. Cable size ampacity chart. 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. The fine stranded wire will pass more amperage than course stranded wire that has a lower strand count.

D intersect current in amps with length in feet to identify the wire size. Fine stranded stereo wire makes great battery cable giving the best gage wire for proper battery charge. Find the current consumption of the load on the horizontal axis of the chart. 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. The following maximum amps versus cable size awg come from the nec version 2011. Sae wire gauge size and amperage for a d c. D n in 0 005 in 92 36 n 39.

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. A size of 4 0 364 30 indicates the gauge size as well as the strand count. Circuit length is 50 circuit type is non critical and correct wire size is 4 awg. 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.

As far as i know these values are valid as of today. Now lets say that you are using a smaller gauge cable for that same length and your voltage drop is 10. 4 0 364 30 simply refers to a 4 awg cable made with 364 strands of 30 awg wire. Battery wire size per voltage amperage load and length chart below shows minimum cable size to use awg wire.

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. The wire size listed in the graph at the intersection denotes the gauge of wire to use. So all interconnecting cables are 2 0 based on the chart below. They don t really understand why it s better.
