Current through Register 2024 Notice Reg. No. 28, July 12, 2024
Service entrance conductors shall have a protective
						  device in each ungrounded conductor, on the load side of, or as an integral
						  part of the service entrance switch. The protective device shall be capable of
						  detecting and interrupting all values of current in excess of its minimum trip
						  setting or minimum melting point which can occur at its location. A fuse rated
						  in continuous amperes not to exceed three times the nominal current rating of
						  the conductors, or a circuit breaker with a minimum trip setting of not more
						  than six times the nominal current rating of the conductors, will be considered
						  as providing the required protection. The nominal current rating of the
						  conductors shall be as required by Section
						  2821.
EXCEPTION: Where the serving agency agrees to provide
						  overcurrent protection in accordance with the above requirement, no further
						  overcurrent protection is required.

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
When the load of an existing service entrance switch
						  increases beyond its continuous current rating or continuity of service
						  requires, a second service entrance switch of identical rating shall be
						  permitted to be connected in parallel with it, provided:
(a) Each switch has interrupting capacity
						equal to or greater than the maximum fault current that can occur at its
						location.
(b) Each switch has its
						own overcurrent protection arranged to trip both switches
						automatically.
(c) Both switches
						have a common electrical or mechanical tripping arrangement.
EXCEPTION: Both switches need not have a common
						  tripping arrangement if continuity of service requires that both switches not
						  be tripped together, under fault conditions, and a suitable relay protection
						  scheme is employed to separate faulted portions from the
						  system.
(d) Both switches
						can be padlocked in the open position.
