Battery Cable Wire Size Chart. The fine stranded wire will pass more amperage than course stranded wire that has a lower strand count. The manufacturers make stock battery cables as small as possible but still get the job done. 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.
If you want to limit your losses to 2 simply divide the distance by 2 5. The wire sizing guide below provides the minimum wire size needed to limit voltage drops to 5 at a given distance in a 12v or 24v system.
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.
Wire gauge calculations wire diameter calculations. If you want to limit your losses to 2 simply divide the distance by 2 5. The following maximum amps versus cable size awg come from the nec version 2011. 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.
