mixing wires

Are you asking about mixing different sizes of conductors on the same circuit?

It is allowed but many consider it a poor practice as changes could be made at a later date that could create a hazard should someone install a larger breaker than the smallest conductor can handle.

Answers based on the National Electrical Code. Local amendments may apply. Check with your local building officials.

mixing wires

you can always over size your wire(for a given breaker size) but never under size your wiring. the smallest size wire determines the circuit size(and thus the breaker size)

Please follow the code - its there for your safety no matter how inconvenient.

Yes it is, but WHY would you need to?? Rarely is there a truly valid reason.
