After running two separate circuits for my daughter's dishwasher and waste disposal, I was told that I could have simply run a three wire cable (still 2 breakers) from the panel box and fed the appliances separately.
I understand the concept, but, there would be 2 hot wires and only one neutral.
Would not that neutral carry twice the current it is designed for?
Thanks for explanations and comments.

My Whirlpool dishwasher and a KitchenAid disposer are on the same 20 amp circuit and never had a problem.

I don't know if it meets code but I can't imagine it is unsafe in any way.

Same here. A receptacle under the sink. One side is "hot" for the DW
and the GD side is "switched".

I think the potential issue here is whether a 20A circuit has
enough capacity to serve both a disposal and a dishwasher.
You'd have to see the spec sheets on both. AFAIK, there is
no specific reqt for separate circuits, as long as the circuit
can handle the current for both. Some cities may have their own
rules too.
