STATUS AT OVERLOADPRESENT CONFIGURATION
LINE1 (L1)
LINE2 (L2)
STATUS AFTER LOAD SHEDDING EVENT
Look at the highlighted AC circuits.
Notice the priority settings for each
circuit (1).
Also, observe that the SHR BKR Rating
is set to 30 amps (2).
Line1 is experiencing an overload
condition at 35 amps (3) exceeding the
SHR BKR Rating of 30 amps by 5 amps.
At this point, Freedom Sequence will
apply its load shedding logic to all
circuits in Line1 and shed the load that
has the lowest priority setting. In this
case, that load is Space Heat with a
priority setting of 6.
After the load shedding event, Freedom
Sequence will report Space Heat as
Off 0.0A (4).
Line1 is no longer in overload condition
at 25 amps (5) not exceeding the SHR
BKR Rating of 30 amps.
