According to 200.4(B), where more than one neutral conductor associated with different circuits is in an enclosure, they must be identified or grouped. Under what condition does Exception No. 1 state this requirement does NOT apply?

• If the enclosure is a junction box larger than 100 cubic inches.
• If the conductors enter from a cable or raceway unique to the circuit that makes the grouping obvious.
• If the conductors are all the same color.
• If the circuits are all part of a multiwire branch circuit.
