@ Tls49, I believe we both were mistaken as to what the Tara labs cobalt power cord's gauge size is, I do know that the conductors are 24 awg, and has 60 of them, you may confirm this on the Tara labs site, according to the wire caculator you supplied, My power cord gauge size is 6 gauge, BTW is really good, or you can use the other caculator, the power cord has three runs of 10 awg, and that turns out to be 5 gauge, either way, The cobalt is not 10 gauge.
