Breaker Derating
According to NEC standards, the total current of all loads in a branch circuit
should be limited to 80% of its circuit breaker rating to ensure that a
combination of continuous and non-continuous loads can run without
tripping the circuit breaker. Freedom Sequence applies this conservative
standard in its load shedding logic. However, when all loads (continuous
and non-continuous) in a branch circuit including its own circuit breaker are
appropriately sized, listed, and rated to handle 100% of their rating,
derating the load capacity is not necessary and 100% capacity can be
utilized.
The option to disable breaker derating is available by changing the default
Enabled to Disabled in Advanced Settings.
For more information on how AC load shedding works, see “AC Load
Shedding” on page 34.
To change the breaker derating from the Advanced Settings screen:
IMPORTANT:
Appliances and circuit breakers that are 100% rated will
have a listing on their product label similar to “Suitable For Use On Single-
Phase ~AC circuits. For 100% Application.”
