2 Gauge Battery Cable Wire Diameter

Wire gauge calculations wire diameter calculations.

2 gauge battery cable wire diameter.

For three our more parallel strings you could reduce by 1 2 cross sectional area 3 awg gauges smaller. Using wire size calculators or our wire gauge chart s can make it easier to determine voltage drop. Now technically one does not have to wire each string series of batteries with the 2 0 wire as you did a simple 8ga wire would should do. The fine stranded wire will pass more amperage than course stranded wire that has a lower strand count.

For one or two parallel strings i would use full size cable for batteries. 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. Wire sizing for battery interconnecting cables 2 0 or 4 0. 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.

Battery wire size per voltage amperage load and length chart below shows minimum cable size to use awg wire. They don t really understand why it s better. 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 number n divided by 39. Negative cable length kit not yet reviewed part number.

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 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. Battery cables grounding 2 gauge black and red 120 in. 2 awg has 665 strands of copper 30 awg ea strand rope lay class k with an outside diameter of stranded copper at 0 320 inches nominal and an overall outside diameter of finished cable at 0 510 inches nominal.

Again my personal opinion. Positive cable length 144 in. D n in 0 005 in 92 36 n 39.
