INSTALLATION AND OPERATING INSTRUCTIONS

Warning

with generators. Gen/Tran accepts no responsibility for accidents, damages or personal injury caused by incorrect installation. These transfer switches are
intended for surface mounting outdoors or indoors.

Caution

conditioners, check the labels on the appliances to be sure they do NOT exceed the rating of the generator. No appliance should have an amperage rating that
exceeds the “GENERATOR MAIN” rating in the transfer switch.

Thank you for purchasing the finest manual transfer switch available today. Gen/Tran’s PowerStay® Manual Transfer Switches are designed to safely connect
generators to load centers in homes and light commercial buildings (single phase only) for standby power applications. Features include:

Typical Outdoor Installation:

: Gen/Tran transfer switches should be installed by a professional electrician familiar with electrical wiring and codes, and experienced in working

: If using the generator and transfer switch for larger appliances, such as electric water heaters, clothes dryers, electric ranges and small air

•

Generator Main and Utility Main are mechanically interlocked preventing utility or generator power back feed

•

Full branch circuit protection with Siemens® circuit breakers

•

Pre-assembled wire harness for easy connection to the load center

•

Optional GFCI, Arc Fault or Surge Protection circuit breakers to further protect your home and electronic equipment (Available from GenTran)

•

High Corrosion-resistant aluminum cabinet

Tools Needed for Installation:

• ¼” and 11/32 nut drivers

• Straight blade and Phillips screwdriver

Other Items Needed:

• NEW 2-pole, 240V Breaker to mount in main load center – amperage to match utility breaker (see specifications Table I for Utility Main Breaker size – should be

manufactured by same as Main load center).

• Anchors and screws to mount switch to wall

• Additional wire connectors if switch is “hard-wired”. See Table 2 for correct size.

• May need Arc-fault, GFCI or Surge protection circuit breakers. If Arc-fault, GFCI or Surge protection circuit breakers are used as the branch circuit protector in the main

load center, they MUST be used in the manual transfer switch. See Table 3 for compatible breakers. (Available through Gen/Tran).

• Power Cord to connect generator to switch.

• Electric drill

• Wire cutter/stripper

Planning Your Installation:

1. Determine the appliances, circuits or equipment you want to operate with generator power during a power outage, such as:

• Furnace

• TV / Radio

• Refrigerator

• Cordless Telephone

• Freezer

2. Complete the following worksheet.: (Refer to TABLE 1 for maximum circuits your manual transfer switch will transfer)

3. Determine the amps required for each appliance using the circuit breaker rating in the load center. No appliance should have an amperage

rating that exceeds the “GENERATOR MAIN” rating in the transfer switch. The total amperage of all circuits can exceed the generator rating,
but not all circuits will be able to be used concurrently.

4. Assign the circuit # in the load center and in the manual transfer switch, matching the size of the circuit breaker in the load center to the

circuit breaker in the transfer switch. Once you’ve completed the worksheet below, you will be ready to begin installing the manual transfer
switch.

Installation Procedure:

IMPORTANT: Please read this entire procedure before beginning installation. WARNING: For SAFETY, turn OFF the MAIN
circuit breaker in the load center BEFORE starting installation. Remember, the wiring ahead of the MAIN is still HOT, even
when the main circuit breaker is off.

For Surface- Installation – “Plug-in” Generator Connection (Models R200660, R300660, R301060, R501210):

1. Transfer switch can be installed on either the left or right side of the main load center. Transfer switch is provided with 21-1/2” of flexible

conduit. The connection to the main load center, using the provided wire harness, must be made through one of the two (2) knockouts
(KO’s) provided in the bottom of the manual transfer switch. The wire harness should enter the main load center in one of the bottom or
lower side knockouts. A 1” or 1-1/4” KO can be cut in the lower side of the enclosure if necessary.

2. Remove the cover of the main load center and the transfer switch. The conduit may be cut to a convenient length. Attach connectors to the

conduit. After attaching the flexible conduit to both boxes through the KOs, hold the transfer switch away from the load center against the
wall on which it is to be mounted and mark the holes on the wall for the anchoring screws. Be sure NOT to stress the flexible conduit, as it
will break. (NOTE: Mounting on LEFT side of existing load center is preferred method. Mounting to right side of existing load center and
routing flexible conduit may interfere with generator cord connection into transfer switch. Reducing washers (not provided) may be needed
if using 2” KO on the bottom left.

3. After mounting the transfer switch to the wall, you are ready to terminate the wires in the manual transfer switch. Fish the bundle of wires

provided through the conduit. Strip each wire in the wire harness approximately 5/8” and insert and tighten the wires to the correspondingly
marked circuit breakers in the transfer switch. As you attach each marked wire to the circuit breaker, write on the label on the cover of the
transfer switch with the appliance on that circuit per the planning worksheet. The unmarked BLACK wires in the harness are inserted into
the Utility 2-pole breaker in the transfer switch. Attach the WHITE wire to the insulated neutral bar inside the transfer switch, and attach the
GREEN wire to the ground bar. Reinstall the dead front to the transfer switch. Cover may be re-installed and padlocked, if desired.
