The shore power cord is designed to continuously carry the 30-amp current flow required to
power each leg of the electrical system. It also creates a critical ground connection between
the vehicle electrical system and the campground shore power receptacle.
Always test the external power source (i.e., the campsite power receptacle or electrical
box) with a ground monitor before connecting your power cord to it. If the ground monitor
indicates ‘reverse polarity’ or an ‘open ground’
DO NOT
connect the power cord.
Regularly inspect the shore power cord for cuts, cracks, worn insulation and other damage.
Have the power cord replaced immediately if problems exist.
Calculating 30 AMP Electrical Load (if so equipped)
When connecting appliances to the electrical system, 120-volt power usage is limited to a
total of 30 amps. Operating appliances collectively places an added load on your 120-volt
electrical system.
An unintentional “trip” of a circuit breaker may occur if you overload the recreation vehicle
and/or campground electrical system. The amperage rating of individual appliances can be
calculated by dividing appliance wattage consumed (normally listed on the appliance) by
nominal design voltage (120 for a 120-volt appliance). For example: 1200 watts divided by
120-volts equals 10 amps.
Solar Prep (if so equipped)
Your recreation vehicle may be wired with a (exterior) plug in that
will allow the batteries to be trickle charged using a free standing
solar panel. In most models, the solar panel kit is a customer
purchased and installed option. The solar plug location will
vary by model, but may be located either on the sidewall, on the
A-frame of the vehicle or in the outside utility center.
There are capped off wires located in the area of the battery. These wires are the battery
charging wires. Once these wires are properly connected to your battery, you will then be
able to plug the solar panel into the charging port.
When the system is connected properly, the solar panel will supply power to the battery, the
battery will supply power to the converter, and the converter will supply power to all the
12V systems as needed.

Replacing Light Bulbs
Before replacing a bulb, be sure the light is off. Do not touch the glass part of the new bulb
with your bare fingers. The skin oil left on the glass will evaporate when the bulb gets hot,
the vapor will condense on the reflector and it will dim the surface.
Replacement light bulbs must be of the type, voltage and wattage listed on the lamp fixture.
Use of incorrectly sized bulbs can overload lamp circuits and may create a fire hazard by
overheating the fixture.
NOTE: Some models may include a solar
panel connection on the roof.
