9. Next, make sure line-to-neutral voltage at T1 and T2 is
approximately 120 volts. If line-to-neutral voltage is not
approximately 120 volts at any point in the system, check
neutral terminations.
10. Make sure there is no voltage on terminals E1 and E2 at the
transfer switch contactor. If voltage is present, switch the
main breaker OFF and check the terminations.
11. Next, check the voltage to the load shedding switch.
12. Check both line-to-line and line-to-neutral voltage on terminals
E1 and E2. Terminations to T1 and T2 were made at the
factory, but still make sure that voltage is correct at these
terminals.

13. Now check the terminations in the sub-panel. If there is a
primary breaker in the sub-panel, make sure it is in the OFF
position. Then check line-to-line and line-to-neutral voltage at
the primary breaker.

VERIFYING LOAD SHEDDING OPERATION

1. Switch the main breaker OFF. If there is a primary breaker in
the sub-panel, make sure it is in the closed (ON) position.
2. Make sure the transfer switch contactor is still in the UP
(UTILITY) position, and use the transfer handle to move the
non-essential load shed contactor UP to the open (SHED)
position. To move the non-essential load shed contactor UP to
the open (SHED) position.
