Cause
Circuit breaker disabled.
MLCB disabled and generator OFF.
Generator power just applied to unit.
Utility power just applied to unit.
Generator was overloaded and shed
occurred.
This load overloaded the generator
while attempting recovery from a shed.
It is in a 30 minute lockout wait period.
The lockout switch is enabled and the
unit is on generator power.
Correction
Enable circuit breaker.
Enable MLCB if utility is present or verify generator
operation if outage.
Wait five minutes plus the priority time delay (see
Table 2-1) for unit to enable output.
Wait 30 minutes from lockout for unit to attempt to re-
apply load.
Review all loads enabled in household. The genera-
tor may experience another overload condition when
this load is enabled. Disable some loads to prevent
generator overload from recurring.
During installation, it was determined that this load
will be disabled during generator operation to prevent
generator overload. Contact IASD for details.
