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.
2 gauge battery cable diameter.
Using wire size calculators or our wire gauge chart s can make it easier to determine voltage drop.
Positive cable length 144 in.
Gauge size awg stranding insulation thickness cable diameter weight per 1000 ft.
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.
1 0 makes great battery cable for large or hi performance 6 cylinder engines and stock v8s.
Use 2 0 battery cables for hard to crank engines like high compression big blocks or diesel engines electric vehicle battery banks depending on controller amperage and large rv power converters house batteries.
As far as i know these values are valid as of today.
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.
Battery cables grounding 2 gauge black and red 120 in.
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.
2 awg 2 gauge battery cable red premium copper battery cable sold by the foot just enter the quantity of feet in the quantity box so 10 is 10 foot length 40 is a 40 foot length etc.
Cable size ampacity chart.
Actually for my current installation i ve sized all of my dc cables to meet the 175 amp worst case scenario.
The following maximum amps versus cable size awg come from the nec version 2011.
Wire gauge calculations wire diameter calculations.
For example for a 12 volt dc system if your load current is 10 amps and your distance of cable is 20 feet your voltage drop would be 1 0 or 11 8 volts at the end of your cable run using a 4 gauge battery cable.
