Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Feeders and branch circuit conductors
						shall have overcurrent protection in each ungrounded conductor located at the
						point where the conductor receives its supply or at a location in the circuit
						determined under engineering supervision.
(1)
						Circuit breakers used for overcurrent protection of three-phase circuits shall
						have a minimum of three overcurrent relays operated from three current
						transformers. On three-phase, three-wire circuits, an overcurrent relay in the
						residual circuit of the current transformers may replace one of the phase
						relays. An overcurrent relay, operated from a current transformer that links
						all phases of a three-phase, three-wire circuit, may replace the residual relay
						and one of the phase-conductor current transformers. Where the neutral is not
						grounded on the load side of the circuit, the current transformer may link all
						three phase conductors and the grounded circuit conductor (neutral);
						and
(2) If fuses are used for
						overcurrent protection, a fuse shall be connected in series with each
						ungrounded conductor;
(3) Each
						protective device shall be capable of detecting and interrupting all values of
						current that can occur at its location in excess of its trip setting or melting
						point.
(4) The operating time of
						the protective device, the available short-circuit current, and the conductor
						used shall be coordinated to prevent damaging or dangerous temperatures in
						conductors or conductor insulation under short-circuit conditions;
						and
(5) The nominal rating of the
						cables will be as required by Section
						2821.
