• Battery cables must always be secured tightly to the terminals. Loose
connections can cause loss of power and arcing power between connections.
• Keep the terminals and cables clean and free of corrosion. Clean
periodically with a wire brush.
BATTERY DISCONNECT SWITCH (If equipped)
About the battery disconnect switch:
• The battery disconnect switch separates the batteries from the 12V distribution center and
converter charging system.
• When 120V AC shore power is connected and the switch is turned ON, the power center is
activated, and the battery(ies) will be re-charged.
• When 120V AC shore power is connected and the switch is turned OFF, the 12V distribution
center will still receive power from the converter, but the battery(ies) is disconnected from the
system and will not be re-charged.
• The batteries will not be discharged or recharged if the switch is OFF.
POWER DISTRIBUTION CENTER
The power distribution center was designed to use a 30-amp 120V main breaker with branch circuits.
Double breakers may be used for the branch circuits. Should a breaker become faulty, replace with the
same type breaker only. Only use approved circuit breakers and 12V fuses.
• Generally, each 12V DC circuit in the distribution center was designed for a maximum 20-amp
automotive style fuse. One or more fuses may be specified at 30-amp. This is the only place a
30-amp fuse should be used.
• Replacement fuses must be the same type and amp rating as originally supplied by the nuCamp
factory. Replacing it with an improper size fuse could result in malfunction.
• The power converter is equipped with reverse polarity fuses. If these fuses “blow” while
connecting the battery, replace with the same type and rating fuse as originally provided with
the equipment.
• While appliances and accessories are connected to the 120V receptacle, the wiring is protected
by circuit breakers in the power distribution center.
• In the event of a failure of a 120V circuit, first check your trailer circuit breakers and the breaker
or 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
by shutting off appliances, such as the air conditioner and microwave, that consume high
amounts of electricity. If that does not solve the problem, consult an authorized nuCamp dealer.
