loaD center
The motorhome is equipped with a 30 Amp 120 Volt AC load center or a 50 Amp 120/240 Volt AC load center.
The load center (circuit breaker panel) contains both AC circuit breakers and DC fuses as well as a power
converter. Shore power goes to the Main breaker. The main breaker provides power to all individual branch circuit
breakers. DC fuses supply power to individual circuits for interior lighting or the furnace for example. Refer to
the panel labels for specific circuit assignments.
WARNING:
This panel contains high voltage that can cause serious injury or death. Before beginning any work
or testing procedures involving the electric panels or any of the branch circuits, be sure to unplug
the recreational vehicle from shore power. Certain testing procedures can require the AC power to
be on. Only qualified technicians with electrical backgrounds should attempt any testing or repair
procedures.
Branch circuits supply AC power to the different items or “loads.” An electrical load is any item or device that
uses current when supplied with an electromotive force. Should a breaker “trip” from an over-current condition,
or from a shorted circuit, the load to which the breaker is supplying the electromotive force should be reviewed or
disconnected to determine the cause of the trip. If no cause is found, or not readily apparent, reset the breaker by
toggling the breaker to the Off position, then back to On. Should the breaker trip again after the load is reapplied,
it may indicate a fault with that particular load.
Do not
continue to reset breaker until the problem is diagnosed
and corrected.
WARNING:
If a fuse blows, replace the fuse with same amperage rating and type. Installing a higher amperage
fuse can damage the wiring or the item the fuse is protecting or may cause a fire. If the fuse repeatedly
blows after replacing, do not continue to replace it. Have the problem diagnosed and corrected by a
qualified technician.
