Ground Fault Circuit Interrupters (GFCIs)
A GFCI is a device that de-energizes a circuit when a current to
ground exceeds a specified value that is less than that required to
blow the circuit breaker. GFCIs are intended to protect people
from electric shocks and are usually required in wet or damp
locations.
Installations in marine and recreational vehicles require GFCI
protection of branch circuits connected to the AC output of the
Freedom XC.
The following GFCI receptacle will work correctly with the
Freedom XC in the inverter/charger’s AC output distribution wiring
system.

Alternatively, the Freedom XC GFCI kit (sold separately; order
PN: 808-9817) option is also available to use with the Freedom
XC inverter unit. See item 11 on page 9.
DC Cabling
This includes all the cables and connectors between the batteries,
the DC disconnect and over-current protection device, and the
Freedom XC. Most mobile installations require multi-strand
insulated cables for flexibility and durability in high vibration
environments and require disconnects and over-current devices.
Electrical wiring sizes in North America are indicated by AWG
notation. In other parts of the world, the metric system is used.
Under the AWG standard, a larger gauge number indicates a
smaller wire diameter. Wire size is usually marked on the larger
sized cables. Table 6specifies the minimum recommended DC
cable size and maximum fuse size for the Freedom XC. The DC
cables must be stranded, copper, and must be rated 90°C
minimum. The cables should be terminated with lugs that fit the
DC stud terminals snugly (

according to manufacturer-specified torque setting.
