Split
phase
input:
No more than 30 amps max in each line.
Because the two lines are out of phase, the
currents from each line subtract in the neutral, and
the neutral current will be approximately zero if the
loads are equal. For example, if Line 1 is supplying
20 amps and Line 2 is supplying 15 amps, the
current in the neutral will be 5 amps.
n
Dual
input:
The neutral current in a dual-input system is the
sum of the two line currents, and must be limited to
60 amps maximum to protect the transfer relay in
the Freedom SW-RVC. Each breaker must not
exceed 30 amps, and the total (sum) of the ratings
of the two breakers must not exceed 60 amps.
AC Output
Protection
The breaker between the Freedom SW-RVC AC
output and the AC loads must be rated to protect
the AC output wire size used. If the AC output
wiring is based on the full 30-amp pass-through
rating, then a 30-amp output breaker is acceptable.
If the AC output wiring is smaller, then the breaker
size will have to be smaller as well, in accordance
with applicable electrical installation codes.
GFCI
Requirement
A GFCI (ground fault circuit interrupter) is a device
that de energizes a circuit when a current to ground
exceeds a specified value that is less than that
required to open the circuit breaker. GFCIs are
intended to protect people from electric shocks and
are usually required in wet or damp locations.
Installation in recreational vehicles requires GFCI
protection of certain branch circuits. Consult all
applicable codes.
Tested GFCIs
Compliance with UL standards requires that the
manufacturer test and recommend specific GFCIs
for use on the output of the inverter. Table 1 lists
models that have been tested and will function
properly when connected to the AC output of the
Freedom SW-RVC.
