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.
