charge the battery as well. The speed and degree of
charge depends on how much power is used for
lights and appliances, as only the surplus goes to
charging the battery. If you are making an extended
stay, then you should keep your trailer hooked up to
a 120-volt current if it is available.
While you are connected to the 120-volt receptacle
the wiring is protected by circuit breakers in the
breaker panel. The circuit breaker panel for the 120-
volt system is in the converter. In the event of a
failure of a 120-volt circuit, first check your trailer
circuit breakers and the breaker for the outlet into
which your trailer shoreline cord is plugged. If a
breaker continues to trip after you have reset it
several times your circuit may be overloaded with
appliances, or there may be a short in the circuit.
Try lessening the load on the circuit. Perhaps an
electric griddle, hair dryer, or an electric heater can
be turned off. If that does not solve the problem,
consult the
nüCamp RV
Service Center.
The 120-volt electrical system provides power to
operate the air conditioner, converter and 120-volt
receptacles for portable appliances. The power is
carded through the 120-volt city power flexible cord
to the 120-volt distribution panel, and then is
distributed to each appliance or receptacle.
All wire, components and wiring methods conform
to federal and state requirements.
Converter
The converter system enables you to use the 12-volt
lights and equipment whether operating on self-
contained battery power or hooked up to 120-volt
city power. The 12-volt light bulbs give off the
same light as regular household bulbs, so that when
operating on self-contained battery power,
everything works normally except the 120-volt
convenience outlets and 120-volt appliances. The
converter system is a transformer designed to
maintain constant output voltages regardless of the
variances that occur in city power systems. The
design eliminates the need for complex electronic
sensing systems to charge the batteries, minimizing
the possibility of failures and greatly increasing its
overall reliability.
In some older parks and other locations where three
pronged outlets are not available, certain
precautions to ensure proper grounding and polarity
must be taken. These precautions are listed below:
1. Attach the three-pronged plug to a two-pronged
adapter. The third conductor line of this adapter has
a short wire lead that must be grounded.
2. For proper grounding connect the short ground
lead to a grounded outlet box or to a cold-water
pipe. When no water pipe is available drive a metal
rod two feet into the ground and attach the ground
lug to it, thus providing the unit with proper
grounding.
NOTE
When the three-pronged plug can be used, there
will be no problems with proper polarity or
grounding with a properly wired shoreline
outlet.
Ground Fault Circuit Interrupter
Most states require trailers with exterior 120-volt
receptacles and receptacles close to a water sources
such as a faucet, to have a ground fault-circuit
interrupter. When properly installed the GFCI
circuit breaker provides reliable overload and short-
circuit protection, plus protection from ground
faults that might result from contact with a HOT
load wire and ground. Each GFCI circuit breaker is
calibrated to trip with a ground current of 5
milliamperes or more. Since most people can feel as
little as 2 milliamperes, a distinct shock may be felt
if the need for protection exists. However, the shock
should be of such short duration that the effects
would be reduced to less than the normally
dangerous level. However, people with acute heart
problems or other conditions that can make a person
particularly susceptible to electric shock may still
be seriously injured.
While the GFCI circuit breaker affords a high
degree of protection, there is no substitute for the
knowledge that electricity can be dangerous when
