50 amp Power Cord
Do not hook up the power cord to any receptacle until you have verified
proper polarity and grounding. Polarity indicators can be purchased in
most electrical and hardware stores.
Do not use any cheater plug, adapter or extension cord to reconfigure
incoming AC power or break the continuity of the circuit connected to
the grounding pin.
Do not connect the power cord into an outlet that is not grounded, or
adapt the power cord plug to connect it to a receptacle for which it is not
designed.
Do not remove the grounding pin to connect to a non-grounded recep-
tacle. Removal of the ground pin disables an important safety feature
designed to prevent shock and electrocution hazards.
Do not connect the power cord to an extension cord. Use of an improper
extension cord will cause overheating of the cord as well as potentially
causing premature failure of the AC equipment.
It is the responsibility of the owner of the electrical receptacle to ensure that the
receptacle is properly wired and grounded. Reverse polarity and/or improper
grounding of your recreation vehicle can cause personal injury or death.
The 50-amp external utility power cord is commonly referred to as the "shore" power cord.
It is designed to mate and properly function with 50-amp "shore" power receptacles avail-
able at most campgrounds.
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.
