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 17 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 branch-rated circuit breaker or fuse (connected
through hard wiring) that is used to supply the
Freedom XC must be rated at no more than 15A
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 branch-rated 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.
