Multiple choice — select the best answer

AThe same phase or leg in the panelboard
BDifferent phases or legs in the panelboard
CEither phase, as long as the neutral is properly sized
DA dedicated circuit breaker for each conductor

✓ Correct answer: B. Different phases or legs in the panelboard The ungrounded conductors of a multiwire branch circuit must be connected to different phases (legs) so the neutral carries only the unbalanced current, which prevents overloading the neutral conductor.
