circuit breaker chosen according to the load current. This may provide quick disconnection of the
short circuited load and operation continuity of the other loads. To obtain maximum protection,
the rating of each individual load circuit breaker shall have the minimum value, which is enough
to carry the full load current continuously.
Rated apparent and active power of the loads shall be less than the UPS power ratings.
