Section 6: Electrical System
The shore power cord is designed to continuously carry the 50-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 indi-
cates '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 50 amp Electrical Load (if so equipped)
When connecting appliances to the electrical system, 120-volt power usage is limited to 50
amps per electrical system leg for a total of 100 amps. Operating appliances collectively
places an added load on your 120-volt electrical system.
A circuit breaker "trip" may occur if you overload the recreation vehicle and/or campground
electrical system. The amperage rating of individual appliances can be calculated by di-
viding 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 pur-
chased and installed option. The solar plug location will vary by
model, but may be located on the exterior sidewall, on the A-frame
of the RV, in the outside utility center, or mounted up on the roof.
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
Solar Plug
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.
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.
