4. Move the selection switch (B) from the utility LINE set-
ting to the GENERATOR setting.
NOTE: This will mechanically prevent the manual transfer
switch "LINE" circuit breakers from being placed in the ON
_osition.
5. Place the desired generator "GEN" circuit breakers (C)
in the ON position.
IMPORTANT: If there is a delay before switching to genera-
tor power during an extended power outage, most or all of
the load devices being powered through the manual trans-
fer switch may start at the same time. To avoid possible
overload damage to the generator, alternate placing loads
on each of the 120 VAC legs of the generator. This is
accomplished by turning the generator circuit breakers ON
one at a time, alternating between the upper and lower cir-
cuit breakers of the manual transfer switch.
Examples:
On the 6 circuit manual transfer switch: Turn on an
upper circuit breaker (labeled "A","B" or "C"), then a
lower circuit breaker (labeled "D", "E" or "F"). Continue
alternating for remaining circuit breakers.
On the 10 circuit manual transfer switch: Turn on an
upper circuit breaker (labeled "A" through "E'), then a
lower circuit breaker (labeled "F" through "J"). Continue
alternating for remaining circuit breakers.
CAUTION: Watch the watt meters (D) to ensure that the
loads do not exceed the rated output of the generator. Main-
tain balanced loads where each of the watt meters stay at
approximately the same level.
Most portable generators do not have the capacity to han-
dle all of the loads that have been wired through the manual
transfer switch at the same time.
Alternate device loads such as a refrigerator and furnace to
avoid exceeding the power output of the generator.

SWITCH TO UTILITY POWER:
1, Place the manual transfer switch "GEN" circuit breakers
(C) in the OFF position.
2. Move the selection switch (B) from the GENERATOR
setting to the utility LINE setting.
3. Place all of the manual transfer switch "LINE" circuit
breakers (A) in the ON position.
4. Shut off the generator and disconnect the power cord to
the inlet box.
Testing:
Periodically switch from normal utility power to generator
power following the procedures above. This will help famil-
iarize the operator with the switching procedures and verify
that the manual transfer switch is operating properly.
Testing will also verify that the devices listed on the labels
are still connected through the listed circuits.
INSTALLATION PROCEDURE
Before Installation:
CAUTION: Determine the load draw requirements of devices
that will be operated through the manual transfer switch.
Loads can be determined using a clamp-on ammeter to mea-
sure actual loads; determined from data plates on each
appliance; or, estimated from the reference guide below.
Balance loads between the two 120 VAC legs of the manual
transfer switch. Refer to schematics.
IMPORTANT: NO load placed through a circuit in the manual
transfer switch should exceed the rating of that circuit breaker.
NOTE: Some electric motors require more than two times
more power for starting than operating. This initial draw only
lasts for a few seconds. Allow for the high starting load draw
in determining load requirements. The load draws given in
the reference guide are approximate load draws for typical
appliances. Refer to the data plates or service literature of
appliances for specific information of that appliance.
