Transfer Switch - Holiday Navigator 2003 Owner's Manual

The transfer switch automatically transfers AC power from the
shore power cord or generator through the transfer switch to the
110/220 Volt AC breaker panel. When using the generator as the
power source, the transfer switch has a time delay built into it
before transferring power to the AC breaker panel. This allows the
generator time to warm up before applying an AC load. When starting
the generator while hooked to shore power, the transfer switch
automatically selects generator power as priority over shore power.
Surge Protector (Optional):
If the transfer switch has a surge protector, electronics are added
to the transfer switch that monitor voltage input for high or low
voltage cutout. If the incoming voltage exceeds 138 Volts, or if
voltage drops below 105 Volts, the transfer switch automatically
disconnects from the electrical service. This prevents damage to
voltage sensitive equipment.
A surge protector with line sensor mounts to the transfer switch.
The surge protector prevents the motorhome from receiving a
sudden "spike" of incoming voltage. This may be from a lightning
strike or a power spike during storm activity.
The line sensor monitors the two "hot" conductors supplying the
main AC panel. If the two incoming conductors have power, the
two green lights illuminate. If only one of the supply conductors
has power, the respective green light extinguishes and the red fault
light illuminates, accompanied by an alarm.
NOTE: To prevent damage to the transfer switch contacts do
not have appliances on or AC loads plugged into outlets when
hooking up to shore power or starting the generator. If the
motorhome is equipped with a standard transfer switch, the
transfer switch will begin to disengage at approximately 90
Volts AC. Operation at this voltage may damage the transfer
switch, appliances or other items plugged into outlets. Start
the generator and disconnect from shore service until the
shore service supply voltage stabilizes.
