Section 6: Electrical System
The campsite 120-volt power receptacle(s) should always be tested for proper function-
ality prior to plugging the recreation vehicle shore power cord into it.
Campsite 120-volt power receptacles can be tested using a digital multimeter or a dedicated
circuit analyzer. Dedicated circuit analyzers plug directly into the campsite power recep-
tacle and minimally test for open neutral, open ground, and correct polarity.
Connecting the Power Cord
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.
To help prevent power surges from damaging the connected loads, please follow these in-
structions when hooking up to the external power source:
1.
Turn off the load center main 120-volt circuit breaker.
2. Carefully extend the entire length of the power cord (approximately 25’-35’) from the
electric cable hatch to the external power source.
3. Plug the power cord into the receptacle. Be sure all the power cord prongs are properly
plugged into the receptacle.
4. Return to your RV and turn on the load center main circuit breaker.
The shore power cord should be unplugged when the recreation vehicle is left
unattended
When you are ready to leave, reverse the power cord connection process. Use care to pre-
vent damaging the power cord electrical connection pins when connecting or disconnecting
the shore power cord. Grasp the plug to remove the power cord from the outlet; do not
unplug it by pulling on the cord.
Maintenance
Inspect the power cord for cuts, cracks and worn insulation. Have the power cord replaced
immediately if these symptoms are noticed.
Power Converter
The power converter converts 120-volt AC power to useable 12-volt DC power when the
shore power cord is connected to an external power source.
The converter has a built-in protective thermal breaker that will shut it down should over-
heating occur. Overheating can be caused by operating the converter above its maximum
power output for an extended period of time, or by an obstruction to its ventilation air flow.
To reduce converter heat build keep unnecessary 12-volt lights and motors turned “off”.
Keep the converters cooling fins and fan clear of obstructions.
 USE ONLY A DEEP CYCLE BATTERY FOR RV USE . Car batteries (CCA
rating) are not designed for RV applications. If doing a lot of dry camping use a
deep cycle battery rated in amp hours only (NO CCA rating).
 If using multiple batteries they must be the same brand and type. Adding more
batteries will provide longer use of DC appliances when not on shore power but
may reduce charging efficiency.
 The battery works in conjunction with the converter to supply DC power to the
RV. A battery is typically only necessary if you do a lot of dry camping or have
slideouts and/or a leveling system.
 Reverse polarity fuse provides protection for the converter when a battery is used.
If the battery is connected backwards to the fuse board this fuse would blow pre-
venting damage to the converter.
 If your lights are dimming or flickering that usually indicates an overloaded con -
verter. Remove some of the load by turning off DC lights or appliances.
