4. Complete the transfer switch wiring by connecting the
equipment ground wires from both the utility and the
generator to the ground lug.
5. Being careful to support the lugs, torque the lugs in the
transfer switch to the specifications shown on the transfer
switch. Decal located on the inside of the switch door.

OPERATIONAL TESTING

1. If installing the RTSD switch, the service was changed so make
sure the terminations are good before re-energizing the utility.
2 Switch the main utility breaker OFF. Refer to NFPA 70-E for the
safety equipment required when working inside a live transfer
switch.
3. Energize the utility and check line-to-line and line-to-neutral
voltage at terminals N1 and N2 on the transfer contactor. If
line-to-line voltage is not approximately 240 volts, de-energize
utility power and check the terminations between the utility
and N1 and N2.
If line-to-neutral voltage is not approximately 120 volts, de-
energize utility power and check the neutral terminations.
Repeat the same voltage checks on terminals T1 and T2 to
make sure current is flowing properly through the contactor.
4. Switch the generator's main circuit breaker OFF and put the
mode switch in the OFF position.
