12 Awg Cable Ampacity

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.

12 awg cable ampacity.

Be aware that the current load depends on installation method the enclosure and how well the resistance heat is removed from the cable. Use the stayonline wire ampacity chart to look up the rated amperage of different sizes and types of cords. 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.
