Transfer Switch Installation Guidelines
HAZARDOUS VOLTAGES ARE PRESENT INSIDE TRANSFER SWITCH ENCLOSURES THAT CAN CAUSE DEATH
OR SEVERE PERSONAL INJURY. FOLLOW PROPER INSTALLATION, OPERATION AND MAINTENANCE PROCE-
DURES TO AVOID HAZARDOUS VOLTAGES.
TURN OFF THE MAIN CIRCUIT BREAKER IN THE LOAD CENTER BEFORE STARTING INSTALLATION.
2.4 — Installation Procedure
1. Transfer switch can be installed on either the left or right side of the main load center. Transfer switch is pro-
vided with 1/2” to 1-1/2” knockouts (KOs) to connect to the main load center and Power Inlet Box using
installer-provided conduit, fittings and wire. The conduit should enter the main load center in one of the bottom
or lower side KOs. If Service Entrance rating is desired, installer must install bonding screw in Hardware Kit
(included) to neutral bar and must apply the Service Disconnect label to the transfer switch as part of the instal-
lation procedure.
2. Remove covers from the main load center and transfer switch. Cut conduit to desired length. Attach fittings to
the conduit and fittings/conduit assembly to both enclosures through the KOs with locknuts. 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. Mount transfer switch to wall with anchors and screws (provided by installer).
3. You are ready to terminate the wires in the manual transfer switch and load center. Install (installer provided)
60A or 100A 2P UTILITY MAIN circuit breaker in main load center. Pull appropriately sized wire (provided by
installer) through conduit and connect RED and/or BLACK wire between the 2-Pole UTILITY circuit breaker in
the transfer switch and the newly installed UTILITY circuit breaker in the main load center, WHITE wire to the
neutral bar inside the transfer switch and main load center, and GREEN wire to the ground bar in transfer
switch and main load center. If there is no separate ground bar in the main load center, connect GREEN wire
into an open position in the NEUTRAL bar in the main load center, and tighten to the marked values.
4. Locate and remove a KO on manual transfer switch for power feed from Power Inlet Box/generator. Install fitting/
conduit as required and pull appropriately sized generator feed wire from Power Inlet Box/generator into manual
transfer switch through conduit. Connect RED and/or BLACK wire to the GEN MAIN circuit breaker, WHITE wire
to the neutral bar and GREEN wire to the ground bar in transfer switch and tighten to the marked values. Rein-
stall transfer switch and load center covers (screws for transfer switch provided in Hardware Kit bag).
5. Turn ON the MAIN load center circuit breaker and all load center circuit breakers. Turn on UTIL MAIN circuit
breaker in the manual transfer switch. Verify that power is restored to all appliances.
