Multi-Wire Circuits and Shared Neutrals
[ad#block]Question: Circuits four and eight share the same neutral, is this correct?

This electrical question came from: Marvin , a Student from San Diego, California.

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, the circuit breakers must be side by side, and the circuit breakers must be have their handles tied.
• Typically a 2-pole circuit breaker is installed.
• This will ensure that each of the two circuits voltage is correct, and the neutral wire load is balanced properly between the two circuit wires.
