4.3 Cables
4.3.1 GPSW150 – 12 V / 24 V
Use the included 3 feet (0.91 m) of #14 AWG wire and automobile DC plug.
When used in conjunction with an automobile DC socket, ensure the DC socket
fuse in the automobile fuse box is rated to the inverter load.
For example:

100 W = 10 A fuse
 150 W = 15 A fuse
If the DC automobile plug is removed and/or the inverter is not attached to a
battery via an automobile fuse box, attach a 20 A fuse in line with the positive
conductor as close to the battery as possible. Extending the included cables may
result in excessive voltage drop. Increase the overall cable gauge to the next
larger standard size for every 3 feet (0.91 m) extended and do not exceed 10 feet
(3.05 m) total inverter cable length.
For example: 10 feet (3.05 m) cable = 10 gauge wire
4.3.2 GPSW300 – 12 V / 24 V
Use the included 4 feet (1.22 m) of #10 AWG wire and Anderson Power Pole
connectors.
Attach a 40 A or 20 A when using 24 volt version fuse in line with the positive
conductor as close to the battery as possible. Extending the included cables may
result in excessive voltage drop. Increase overall cable gauge to the next larger
standard size for every 3 feet (0.91 m) extended and do not exceed 10 feet (3.05
m) total inverter cable length.
For example: 10 feet (3.05 m) cable = 6 gauge wire
4.4 Grounding
The inverter has a chassis ground lug on the rear panel allowing you to connect
the chassis of the inverter to ground. The ground terminals in the AC outlets on
the front panel of the inverter are internally connected to the chassis ground. If
available, the chassis ground lug should be connected to a grounding point,
which will vary depending on where the inverter is installed. In a vehicle, connect
the chassis ground to the chassis of the vehicle. In a boat, connect the chassis
ground lug to the boat's grounding system. In a fixed location, connect the
chassis ground lug to an earth ground.
The neutral (common) conductor of the inverter AC output circuit is connected
(bonded) to the chassis ground inside the inverter. Therefore, when the chassis
is connected to a ground, the neutral conductor is also grounded. These
grounding connections conform to national electrical code requirements which
state that separately derived AC sources (such as inverters and generators) have
their neutral tied (bonded) to ground in the same way that the neutral conductor
