What makes a tap not a feeder or branch circuit conductor?

[petersonra]

The definitions do not result in mutual exclusivity. You can have the following arrangement:

OCPD 1 - Conductors A - Outlet 1 --- OCPD 2 --- Outlet 2.

Then Conductors A are a feeder with respect to OCPD 2 / Outlet 2 and a branch circuit with respect to Outlet 1.

that is not what the post referred to though. he said something about an A/C disconnect being fused. Unless there are additional OCPD downstream in such a circuit, the fuses in the fused disconnect are the final OCPD. he did not say anything about there being any additional OCPD downstream.

E.g. run a circuit to a roof for an 208Y/120 HVAC unit with an unfused disconnect. Tap the circuit for a 20 amp OCPD for a service receptacle.

The post referred to did not have an unfused disconnect and said nothing about a receptacle.

My comments weren't about the OP, merely the question of whether circuit conductors can be simultaneously a feeder and a branch circuit, or whether the definitions are mutually exclusive.

And mine was merely that this has been discussed before in reference to an A/C circuit.

BC starts from the last OCPD. Upstream is a feeder

Yes, for any single outlet, it's well defined which upstream wires are branch circuits and which ones are feeders, and those are mutually exclusive.

But the same piece of wire may be a branch circuit with respect to one outlet and a feeder with respect to another outlet.
