JAYCO TOWABLE SECTION 6 – ELECTRICAL SYSTEM
6-5
The shore power cord is designed to continuously carry the 30 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.
120-VOLT CIRCUIT BREAKERS
The 120-volt AC circuit breakers located inside the load center protect all 120-volt wiring
and components in the recreation vehicle from circuit overloads and short circuits. Should
a circuit overload or short circuit 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.
NOTE: Load Centers may not always include a main circuit breaker.
Replacement
Only replace circuit breakers with those of the same specified type, voltage, and current
rating. Never replace a circuit breaker with one listed at a higher amperage rating.
Please contact your dealer for repair assistance when replacing circuit breakers.
Maintenance
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.
A label is provided to explain the function of every 120-volt circuit breaker. This label is
located on or near the appropriate load center or sub-panel and must remain permanently
affixed to the recreation vehicle.
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
