24、nductors between the nal over-current device protecting the circuit and the outlet(s). 2.4 BRANCH CIRCUIT, MULTIWIRE A branch circuit that consists of two or more ungrounded conductors that have a voltage between them, and a grounded conductor that has equal voltage between it and each ungrounded co
25、nductor of the circuit, and that is connected to the neutral or grounded conductor of the system. 2.5 CLASS 2 CIRCUIT An isolated secondary circuit involving a potential of not more than 30-volt rms maximum 42.4 volts peak open circuit secondary potential under any condition of loading or open circu
26、it by: a) An inherently-limited Class 2 transformer; b) A combination of an isolated transformer secondary winding and a xed impedance or regulating network that together comply with the performance requirements for an inherently- limited Class 2 transformer; c) A dry-cell battery having output char
27、acteristics not greater than those of an inherently-limited Class 2 transformer; d) Any combination of (a), (b), and (c) that together comply with the performance requirements for an inherently-limited Class 2 transformer; or e) One or more combinations of a Class 2 transformer and an overcurrent pr
28、otective device that together comply with the performance requirements for a noninherently-limited Class 2 transformer. A circuit derived from a line-connected circuit by connecting impedance in series with the supply circuit as a means of limiting the voltage and current is not considered to be a C
