    Hi, I am new to the forum and I learned from a different thread that I need to use 16 gauge wire for a 30 foot run.

    I have lots of 20 gauge, so my question is what is the relationship between gauges?

    Would two runs of 20 gauge equal 18? 16?

    In general is each gauge one half the previous?

    If this has been discussed before please direct me to the thread. My search failed to find anything.

    Thanks,

    In comparing wire gauge sizes you must look at the area of the wire, not the diameter.

    Two 20AWG will yield a 17AWG wire.

    You always go three gauge sizes when combining two wires of the same gague:

    Two 20AWG = One 17AWG
    Two 18AWG = One 15AWG
    Two 16AWG = One 13AWG
    Two 14AWG = One 11AWG

    Four 20AWG = Two 17AWG = One 14AWG

    Eight 18AWG = Four 15AWG = Two 12AWG = One 9AWG
