2. Determine if the wiring harness needs to be shortened. If so, remove the wires from the wiring harness and cut
conduit to desired length. [NOTE: The Electrical Non-Metallic Tubing (ENT) provided is UL Listed and recog-
nized by the National Electrical Code (NEC). However, some local codes and inspectors may prohibit its use in
buildings that exceed (3) floors above grade.]
3. Attach the wiring harness to the load center; hold the transfer switch in position against the wall on which it is to
be mounted and using the provided template, mark the holes on the wall for the anchoring screws and anchor
transfer switch to wall (anchors not provided).
4. Remove transfer switch cover, save screws, allow the cover to hang down, supported by the wattmeter wires.
5. Install appropriately sized conduit, fittings and wire between the Power Inlet Box (PIB) mounted on the building
exterior and the transfer switch, referring to section III – Power Inlet Box installation instructions below. Locate
and remove a KO in the transfer switch, pull wire into transfer switch enclosure and secure wire with fitting.
6. Using provided wire connector, connect the generator green ground wire with the green wire inside the transfer
switch. Connect the generator white neutral wire into neutral bar on the left. Using provided wire connectors,
connect the generator black wire to black wiring going to Meter “A”. Repeat for generator red wire to Meter “B”.
See FIGURE 2 WIRING DIAGRAM. Reinstall transfer switch cover.
7. In the main load center, remove the wires from the breakers for the loads that will be relocated to the transfer
switch. Cut each blue harness wire (A4-B6) to a convenient length, strip off 5/8” of insulation and connect to
the wires removed from the breakers per TABLE 2 with the provided wire connectors.
8. Remove two adjacent single pole breakers from which the load wires were removed and install the NEW 60A
2-pole circuit breaker (as required in the Other Items Needed section) in their place. Insert the unmarked
BLACK wires from the harness into the new circuit breaker. Terminate the WHITE and GREEN wire in the har-
ness in an open position in the Neutral and Ground bars respectively. If there is no separate ground bar, insert
the GREEN wire into an open position in the NEUTRAL bar, and tighten.
9. Reinstall the main load center dead front cover, and turn ON the MAIN breaker in the main 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. Installation is now complete.
II. EXPANDING OR RECONFIGURING YOUR TRANSFER SWITCH:
This transfer switch ships from the factory with certain popular branch circuit breaker sizes. However, the circuit
breaker assortment can be modified to suit specific requirements, and this does not void the UL Listing. For example, if
the 2-pole 20 amp circuit breaker is not needed, it may be removed from the panel and replaced with any combination
of the following: two separate full size breakers, two tandem breakers, one full size and one tandem, or a triple/quad
breaker. If additional circuits are added, the installer is responsible for providing appropriately sized wire(s) for each cir-
cuit.
III. INSTALLING THE POWER INLET BOX (Models 6294 and 6408 Only):
1. Remove the front cover of the power inlet box. Remove the 3 screws that secure the flanged inlet to the bottom
plate.
2. Mount the power inlet box on the outside of the building in a convenient loca-
tion (minimum 24” above grade), using the four holes provided in the back of
the enclosure. Use sealant around the anchoring screws to keep water from
entering the box at these mounting holes. Using approved wiring methods,
install the wiring through one of the knockouts provided in the enclosure. Be
sure to seal around the hole in the building where the conduit enters through
the wall.
3. Extend wiring inside the power inlet box approx. 8” from the point of
entrance. Attach green or bare ground wire to green lead provided in power
inlet box with wire nut (provided by installer). Strip and insert incoming leads
into terminals on flanged inlet. Insert white wire (neutral) into nickel-plated
screw terminal or white marking on the flanged inlet.
4. Carefully fold wires into the enclosure and reattach the bottom assembly or
inlet onto box with screws removed earlier. Installation is complete.
