Re: How many strands of 30 AWG twisted to make 20AWG?

38.28.19.40

You would need about 10 strands. The math is simply dividing the 20 gauge cross section area by the 30 gauge area. The wire gauge diameters are available in a chart or website like http://www.coilcraft.com/awg.html. The area is simply pi * radius * radius (where pi = 3.1414).

A simple approximation is that every doubling of the number of conductors will lower the gauge about three numbers, two 30 AWG wire will equal one 27 AWG, four = 24AWG, eight = 21AWG.
