Wiring the Inverter/Charger

AC Wiring
Overview The U.S. National Electrical Code (NEC) defines the standards for AC and DC
installation wiring in RV applications, but there are still many installation
variables. Most are determined by the level of automatic switching desired and the
amount of external AC power to be switched.
Installation should be done by a qualified electrician. Consult local code for the
proper wire sizes, connectors and conduit.
The AC and DC terminals are located on the same end of the chassis as the status
LED and power switch. A six station terminal block is provided to connect the AC
input and AC output. All terminals are labeled on the inverter. Consult your local
code for proper wire sizes, connectors, conduit, and so on. See Table 2-1 for
minimum recommended wire sizing. Code requires that an external disconnect
switch be used in the AC input wiring circuit. The AC breakers in a sub panel will
meet this requirement.
