STEP 2: INSTALLATION PROCEDURE:
HAZARDOUS VOLTAGES ARE PRESENT INSIDE TRANSFER SWITCH ENCLOSURES THAT CAN CAUSE DEATH OR SEVERE PERSONAL INJURY. FOLLOW PROPER INSTALLATION, OPERATION AND MAINTENANCE PROCEDURES TO AVOID HAZARDOUS VOLTAGES. TURN OFF THE MAIN CIRCUIT BREAKER IN THE LOAD CENTER BEFORE STARTING INSTALLATION.
I. TRANSFER SWITCH INSTALLATION:
A: Surface Mount Installation Using Power Inlet Box (included in models
1.Select a location on the left or right side of the Load Center to mount transfer switch, as it is provided with 21.5” of flexible conduit. Remove the cover to the load center and the cover of the transfer switch, save the screws. Measure and cut conduit to a length and snap provided fittings on ends. Locate and remove a knockout (KO) on lower side of load center that matches the conduit fitting size on the wiring harness. After attaching the flexible conduit to both enclosures through one of the bottom or side KOs, hold the transfer switch in position against the wall on which it is to be mounted, mark the holes on the wall for the anchoring screws and anchor to wall (anchors not provided). Be sure NOT to stress the flexible conduit, as it may break. [NOTE: The Electrical
2.Fish the
3.Install appropriately sized conduit, fittings and wire between the Power Inlet Box (Models
4.In the main Load Center, remove the wires from the breakers for the loads that will be relocated to the transfer switch. Cut each harness wire to a convenient length, strip off 5/8” insulation and connect to the wires removed from the breakers per TABLE 2 with the provided wire connectors. Remove two adjacent single pole breakers from which the load wires were removed and install the NEW 60A or 100A
5.Reinstall the cover to the load center, and turn ON the MAIN breaker in the load center. Turn ON all branch circuit breakers in both panels. Turn ON the UTIL MAIN in the transfer switch. Check that power is restored to all appliances. Transfer switch installation is complete.
B. Flush Mounting in New Construction (unfinished walls) Using Power Inlet Box (included in
1.Install the transfer switch at the same time as the main load center, in adjacent wall stud openings (the transfer switch enclosure is 14.25” wide and will fit in standard 16” wall framing). Remove the transfer switch dead front cover, save the screws. Knock out the appropriate mounting slots on the sides of the enclosure and secure to framing with nails or screws; be sure the front edge of the enclosure extends forward to be flush with the thickness of the finished wallboard.
2.Mark and drill a 2 1/8” diameter hole in the stud between the main load center and the transfer switch, lining up with the lowest side KO in the load center and near the bottom center KO in the transfer switch. Remove the KO’s, cut the provided conduit to length, snap on the provided fittings to the conduit, push the conduit through the drilled hole and install the conduit assembly to the KO openings in the main load center and transfer switch.
3.Complete Section IA3 above. Cut a piece of cardboard to 14.5” x 12.5”, using the 4 screws removed in step IIA1, attach the cardboard to the front of the transfer switch.
