That makes perfect sense.Thanks!

My thoughts concur with Terry’s. You would be effectively using only the DC resistance of 500 ft of #12 copper stranded wire, as the inductive reactance of each 250 ft piece would cancel out. That’s he reason an amprobe meter will only accurately measure the current flow through a single conductor but won’t work when placed over both the hot and neutral together.

Or should I unroll all of the wire and separate it into two 250-foot single conductors, connect them together, and then re-roll what would then be a 500-foot single conductor wire.
