Branch Circuit, Multiwire, NEC 2020 - [210.4], (19min:38sec)

Multiwire branch circuits are a cost-saving wiring technique that shares one common neutral conductor between multiple branch circuits. This technique saves wiring costs but introduces a handful of dangerous side effects, including potential confusion, safety, and equipment damage risks. Multiwire branch circuits require each phase conductor to be on different phases. Doing this guarantees their shared neutral will never need to carry a higher current than any of the phase conductors, which is why it is possible to use the same ampacity for all the current-carrying conductors of the multiwire branch circuit. Preventing the need to use a larger neutral conductor, is where the cost savings happen, so this is only permitted by the code when the phase conductors are on different phases.
