So I am wiring up some led's and I need some pretty thin wire. I have 30 awg but not sure of the current it can handle. It will be one 3mm red led per wire so nothing major but what do you all think.

Shows .86 amps far under the draw if a single LED

We need to know the voltage and current you are running the 3MM LED at before anyone could accurately say if it is safe or not.

how long is the wire too?

From what I was always taught, the length creating more resistance is a factor no?

Yes, length will create extra resistance, but its minimal extra resistance unless you are running really long distances.

Agreed. We never figured it unless it was over 100 feet.
