Calculating Cable Sizes
To operate safely and effectively, the Duracell needs proper cables and
fuses. Because the Duracell has low-voltage and high-current input, it is
essential that you use low-resistance wiring between the battery and the
inverter to deliver the maximum amount of usable energy to your load.
For safe and efficient operation, you will need to calculate cable sizes for
your:
• DC input cables from the battery to inverter (one way)
• Chassis ground cable from the grounding point to the chassis ground
screw on the inverter’s DC panel.
See Figure 3-3 on page 3–12.
Calculating Size of DC Input Cables
Refer to Table 3-1 to plan the DC input cabling for your particular
application:
• Keep all cables as short as possible, and ensure that each cable
between the inverter and the battery is no longer than 5 feet (1.5 m).
• Do not use aluminum cable. It has about 1/3 more resistance than
copper cable of the same size, and it is difficult to make good, low-
resistance connections to aluminum wire.
• We recommend that you use oil resistant cable.
WARNING: Fire hazard
Never use a cable longer than 5 feet (1.5 meters). A cable longer than 5
feet (1.5 meters) can potentially generate enough heat to start a fire or
result in poor inverter performance.

Note : Never use a cable longer than 5 feet (1.5 m) with the Duracell.
Appropriately sized cable can be bought at a welding supply house or a
marine supply store.
