Notes: The NEC requires
overcurrent protection for wiring
and equipment in both AC and DC
circuits. As shown in this diagram,
the RVIA allows the following
application when an inverter is
installed in a RV.
Pass-thru mode: When the AC
source (generator or shorepower)
powers loads through a transfer
switch (i.e., pass-thru mode),
the conductor from the transfer
switch to the dedicated load
will be protected as long as the
branch rated circuit breaker at he
AC source does not exceed the
ampacity of the conductor feeding
the dedicated load.
Inverter mode: When the
inverter is powering loads using
power from the battery (i.e.,
Inverter mode), the conductor
from the inverter output to the
dedicated load will be protected
as long as the ampacity of the
conductor is sized based on the
inverter’s AC output rating. In
Inverter mode, the inverter has
overcurrent protection to limit the
output current and to protect the
conductor.
