Dave’s Reply:
Thanks for your electrical question Marvin.

Multi-Wire Circuit Wiring

Marvin, if the circuit breakers are full size then no, this is not correct. A multi-wire circuit that shares the same neutral must have each of the two circuits on separate buses, and the circuit breakers must be have their handles tied. This will ensure a balanced load on the neutral.
