AC Shore Power
A source of 120 volts AC 60Hz sine wave alternating current
provides energy to pass power through to AC loads. This source
is usually the utility grid (power company) or an AC generator. An
automatic or manual AC source selector switch can be used to
switch between the multiple sources of shore power to the
Freedom XC system.
The AC source feeding the Freedom XC must have the neutral
conductor bonded to ground. When the inverter/charger passes
shore power through, it will lift its internal bonding relay on the
output and will rely on the input neutral being bonded in order to
ensure that the power delivered to a sub panel is properly bonded.
See
AC Output Neutral Bonding on page 19 for more information
on bonding relay operation.
NOTE : Throughout this guide, the term “shore power” refers to AC
input power from a utility grid, generator, or other AC source.
AC Disconnect and Over-Current
Protection Device
Most safety requirements and electrical codes require the
Freedom XC’s AC and DC inputs and outputs to be provided with
over-current protection (such as circuit breakers or fuses) and
disconnect devices.
AC Input
The circuit breaker or fuse (connected through hard
wiring) that is used to supply the Freedom XC must
be rated at no more than 30A and must be approved
for use on 120 volts AC branch circuits. The wire
used between the breaker and the Freedom XC
input must be sized adequately to carry current up
to the rating of the input breaker and in accordance
with the electrical codes or regulations applicable
to your installation.
AC Output
The circuit breaker or fuse must be rated at no more
than the rating of the input breaker in the installation
and must be approved for use on 120 volts AC
branch circuits. The wire used between the
Freedom XC and the AC output breaker must be of
adequate size to match the AC input circuit
breaker’s rating. The wiring from each AC output
breaker to each of the loads must be adequately
sized to carry the current rating of the individual AC
output breaker.
