Source vs Output circuits

[Grouch1980]

When you have a large PV array (with no optimizers), and you have multiple combiners going to a recombiner, and the recombiner output goes to the inverter... are the wires between the multiple combiners and the recombiner considered source or output circuits? I am assuming they are considered output circuits.

They are output circuits. A source circuit contains only solar modules in series. Once it's paralleled to another circuit or connected to another device it becomes something else.

One could argue that source circuits are a subset of output circuits, but I'm not sure it makes a meaningful difference to anything.

Great! Thank you sir.

Get ready for the 2023 NEC where it looks like they are doing away with the concept of source and output circuits.

By the time NYC adopts that code it will be the year 2050

Being in CA I feel your pain of the delayed adoption. On the upside, we get to let MA work out the bugs in a new code.
