N ot es: 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 where an
inverter is installed in a RV.
Pass-thru m ode: When the AC source
(generator or shorepower) powers
loads thru 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 the
AC source does not exceed the
ampacity of the conductor feeding
the dedicated load.
I n vert er m ode: 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.
