Technically is a 2P circuit one or two circuits? I think I remember hearing some debate over this. Thanks.

It can be either. If you have a MWBC it can be two circuits, if it's just a 2-wire branch circuit like a 240 volt heater than it's one circuit.

A MWBC can also be considered as one circuit also. Depends.

In particular, it is one circuit when you are limited to one circuit (as in feeding a detached structure), and it is two circuits when two circuits are required (as in SABCs in a kitchen.)

My exact thoughts.

I often cite those examples and that's the reason I used the words can be in post #2.

Sort of like the way some wires can be both feeder wires and branch wires at the same time. (Ducking quickly for cover. :angel

T'was my inspiration.

It is 1 or 2 depending what benefits me the most.

Say, can I have a word with you.....

I don't quite get that. Can you explain a little more. Thanks,

Read 210.4(A). The reality is that a MWBC is a single circuit but the code allows it to be considered multiple circuits.

One of the factors for that is that like any circuit with multiple hots and a common neutral serving line to neutral loads it can be split up at any point into single hot plus neutral runs to outlets (receptacle or other). And yet it is not a feeder.

Will do.
