Thumbs down How to ID neutral

HI friends, I been using a non- contact voltage probe to trace some K&T wiring [ two hot and two neutrals running parallel to eachother from the panel trough heating ducts,cold air return and wall cavities] my question is how can i identify the neutral and hot that form a circuit?
Thanks a lot

unplug everything connected to the circuit and turn off all loads. The wires with no voltage will be the neutrals. Otherwise, K&T makes no differentiation between the hot and neutral.

I think papi was asking how to tell which neutral goes with which hot. That's important to know so that you don't overload the neutral.

If you disconnect the neutrals at the panel, you can test it with an ohmmeter and a long wire. Or disconnect just one of the neutrals at the panel and its associated hot and see which hot/neutral pair still has power at the outlet.

But if you're working on K&T, I suggest you spend your time replacing it.

Thanks for the clarification, John. I didn't read enough into the question.
