Car battery cable gauge size. Fine stranded stereo wire makes great battery cable giving the best gage wire for proper battery charge. 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. 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.

6 gauge awg 11 8 ft. 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. Very large wires may measure with numerous zeroes. Below we reference the two things you must double check when sizing your battery cables.

Now lets say that you are using a smaller gauge cable for that same length and your voltage drop is 10. 4 gauge awg 18 8 ft 9 4 ft. Wiring sizes measure from smallest to largest on a numerical scale that starts with a zero for the largest sizes and gets smaller as the numbers go up. But to enable this you need to make sure the sizing is correct.

6 3 ft 4 7 ft. 2 0 awg 2 0 gauge single red 2 feet w 5 16 lugs pure copper powerflex battery inverter cables for solar rv auto marine car boat 4 9 out of 5 stars 19 22 96 22. The fine stranded wire will pass more amperage than course stranded wire that has a lower strand count. A 000 gauge wire is bigger than a 00 gauge wire which is bigger than a 0 gauge wire.

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. It ensures you have power stay on task and avoid battery drain. 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 wire size per voltage amperage load and length chart below shows minimum cable size to use awg wire.

A size of 4 0 364 30 indicates the gauge size as well as the strand count. A battery cable with the wrong gauge is one of the most common issues in improper installations. 2 gauge awg 29 8 ft 14 9 ft 9 9 ft 7 4 ft 4 9 ft. Battery cable size 50 amps 100 amps 150 amps 200 amps 300 amps.
