Battery Connections

2.2.
Battery cables provide the link between the batteries, equipment and charging system.
Faulty connections can lead to poor performance and terminal damage, meltdown or
fire. To ensure proper connections, please use the following guidelines for cable size,
torque values and terminal protection.

Cable Size

2.2.1.
Battery cables should be sized to handle the expected load. Refer to
the maximum current carrying capacity (amps) based on the cable/wire gauge size.
Table 1
Table values are for cable lengths less than 6 feet (1829 mm). In series/parallel
battery banks, it is preferable for all series cables to be the same length and all
parallel cables to be the same length.
For more information refer to the National Electric Code for correct cable/wire size,
which can be located at www.nfpa.org.
