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
X system.
The AC source feeding the Freedom X must have the neutral
conductor bonded to ground. When the inverter passes shore power
through, it will lift its internal bonding relay on the output and will
rely on the input being bonded in order to ensure that the power
delivered to a sub panel is properly bonded. See “AC Output
Neutral Bonding” on page 15 for more information on bonding
relay operation.
Throughout this manual, 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 X’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 X 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
X 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 X 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.
Disconnect Devices: Each system requires a method of
disconnecting the AC circuits. If the over-current protection devices
are circuit breakers, they will also serve as the disconnects. If fuses
are used, separate AC disconnect switches will be needed ahead of
the fuses. These will have to be a branch circuit rated for 120 volts
AC and have an appropriate current rating.
