AC
SYSTEM
The following electrical components (if so equipped) will only operate when your
RV is connected to shore power: 120 to
12-volt power converter, air conditioner,
120-volt refrigerator, microwave oven, television(s), fireplace and appliances
plugged into convenience receptacles.

CIRCUIT
BREAKERS
The 120-volt AC circuit breakers located in
side the main load center protect all
120-volt wiring and components in the RV fr
om circuit overloads and short circuits.
Should a circuit overload or short circui
t occur the circuit breaker protecting the
affected circuit will "trip" preventing the flow of electricity through that circuit.
If a circuit breaker trips, shut "off"
the appliance on that circuit (i.e., power
converter etc.) and allow the circuit breaker to cool down for a brief period of time.
After the cooling down period, reset the circuit breaker by moving its lever "off" and
then back to the "on" position. If the circuit breaker re-trips or frequently trips,
contact your dealer to have the electrical problem diagnosed and repaired.
A circuit breaker identification label is permanently attached to the inside surface
of the 120-volt load center.
Maintenance and Replacement
At the beginning of camping season, inspect the circuit breakers and replace as
needed. Test by turning each circuit breaker "off" and back "on". Circuit breakers
are wearable parts and must be replaced
as needed, as part of your RV
maintenance. If you have any questions, consult your dealer.
Please contact your dealer for repair assistance when replacing circuit breakers.
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
overheating 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 converter cooling fins and fan clear of
obstructions.
Inspection and maintenance
If the 12-volt power converter is not working (auxiliary battery not being charged)
check the reverse polarity fuse(s) in the converter fuse panel.
There are no
customer serviceable parts inside the converter case and the
manufacturer's warranty will be void if
the case has been removed
. If you
have further concerns contact your dealer.

Want to install split unit aircon in my caravan but see it only has a 16amp breaker, would this be able to run fridge, kettle and aircon at the same time?

It needs to be determined wether it's a dead short or the compressor is bad. A dead short is when the hot (colored) wire is in contact with the neutral (white) wire in a 120 V system.
I would get to the compressor connection box and disconnect the power from the compressor and turn the circuit breaker on. If it trips, it's a wiring problem. If it doesn't trip, the compressor is shorted internally.
As an alternate test to disconnect the compressor, you can turn the thermostat to off and reset the breaker, if it trips, then it's a wiring problem, if it doesn't trip and as soon as you turn the thermostat to on, then you must go to disconnecting the compressor and check it again with the compressor disconnected.
Other tests, an electrical meter is required.

Always unplug the appliance before working on it.
I would suggest checking the circuit breaker in the breaker box for your apartment, to see if it has tripped. You have probably already done this, but try to reset (open all the way and then close) the circuit breaker. Plug the power cord in again and try to operate the dryer.
If it trips the circuit breaker again, there is a short circuit or a ground, and you should unplug the machine and diagnose the problem. 240 volts AC, when shorted or grounded can start fires or kill people.
Many Dryers are equipped with a "non-resettable thermal fuse". When the air being blown through the dryer gets too hot, this thing melts and opens up the entire power circuit.The dyer doesn't do anything, as if it had no power.
This non-resettable thermal fuse can usually be purchased from the manufacturer or a good appliance supply store, and comes in a kit which also includes a new thermostat, to replace the one that probably failed and overheated the machine to start with.
Get a friend who is an Electrician to help you if you are at all unsure of replacing parts in your power circuit. Be sure to unplug the machine / use a VOM to check it dead before you touch anything electrical. BE SAFE. 240 Volts AC is not just playing around.

Circuit breakers for water heaters generally operate at their maximum current. Once in a while a circuit breaker will trip for no apparent reason. The other reason may be a fault with the element or the thermostat. If this is the case it will generally happen again. If it does the element and thermostat need to be tested. If there is a fault the c/b on the HWS should always trip before the one at the switchboard providing that they are the same rating.

well mineswas a blowen compressor

my duo therm air works beautifuly all day but at night when we go to bed it seams to turn on and shut off rapidly. what could be wrong?

Blank screen sounds like a fried thermosat. Abrupt outages can affect certain types of thermostats. Make a jumper wire and jump across R and G. See if you get any action from anywhere. If a fan or compressor kicks in you know you have a burned out thermosat...
