TRANSFER SWITCH
Your coach is equipped with an automatic 110-VAC input power transfer switch. This switch will
automatically switch the input circuit as it is activated.
NOTE
the generator is the dominant power source and
will remain as the AC supply source even with the shore cord plugged in.
CAMPGROUNDS AND SHORE POWER AMPERAGE
As previously stated, most campgrounds will provide a 30-amp service hook-up. There are some older
campground state parks that only provide the 15-amp. Do not hook-up to the power source without talking
with someone at the campground and finding out what type of service they provide.
If you hook up to a power source that is a lower voltage, you could damage your electrical system or its
components. A polarity checker is available through your dealer. Checking before you hook up could save you in
costly repairs.
SHORELINE/POWER CORD
The detachable weather-resistant heavy-duty shoreline/power cord transfers the 120-VAC power from external
power source to the inverter and some110VAC circuits wired directly from the transfer switch. inside the unit. The
30-amp system uses a cord with a 3-prong grounding plug and a 50-amp system (if equipped) uses a cord with a
4-prong grounding plug. To help reduce the load on your 12-volt DC battery you should use this system whenever
possible.
When using the shoreline/power cord follow these steps to maximize the protection against creating a shock
hazard.
Before you connect your power cord, make sure that your connections are clean and solid. Dirty contact or
connections can result in low voltage.
For maximum protection against fire or an electrical shock, do not use an extension cord. Extension cords reduce
the voltage to your system. If you do intend to use an extension cord, be sure to use one with a same current
rating required for your system. The original shoreline/power cord provided is the correct length and amperage.
When necessary, replace with the same type and specifications.
Do not use a cheater plug (adapter cord) or an extension cord with a current rating
less than the amperage of your motorhome requirements.
Always use the appropriate cord. Never mix the cord types or plug into a different
type receptacle by removing any of the prongs. You could be creating a potential fire
hazard.
Always disconnect the cord set from the power source before performing any maintenance.
Failure to disconnect the cord set could result in electrocution.
To reduce shock, follow the proper steps to connect and disconnect the shoreline power.
