I ordered the wrong wire at mouser and I have a question:
Is there a risk/disadvantage to use 30AWG wire for analog circuitry instead of 22 or 24? I mean is it too thin to wire pots, jacks, bananas... in term of conduction?
Can I wire also to a power supply or is it made to use with digital circuits?
I have no idea if the thickness is important for current transfer for instance.

Thickness has SOME importance in conduction of current, I would not use thin wire for power supplies because it could heat up more than it should.

But the main problem I would have using 30ga for panel components is physical strength. I have enough trouble in some projects with resistor leads and such if they're not carefully relieved of strain.

Same opinion here about strength. It is very, very thin. I ordered new wire.
Thank you!

I found this page with AWG table (incl. drop and load realtime calculations) and forgot to post the link here. I thought it might be useful for others too:
