2.2 Battery Connections (continue from pg 5)
If using washers, it is very important to ensure the battery wire connection is contacting the lead surface
of the terminal and the washer is placed on top of the wire connection. If you place the washer between
the terminal lead and the battery wire, this creates high resistance and can cause terminal meltdown.
2.2.1 Cable Size
Battery cables should be sized to handle the expected load. Refer to Table 1 for the maximum amps
based on the cable/wire gauge size.
Table 1
Cable/Wire Gauge Size (AWG) Ampacity (amps)
14 25
12 30
10 40
8 55
6 75
4 95
2 130
1 150
1/0 170
2/0 265
4/0 360
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.
