Does this affect the electrical properties? Peter My opinion: Look up the power transmission characteristics of your proposed wire. Wire has a certain ohms per unit length per cross sectional area and per metal composition of the wire. Increasing the length means power loss. Thinning the wire means power loss. If I were to thin the wire then I would double the number of strands. i.e.: run a pair of 20 gauge stranded vs. a single 16 gauge stranded for the same power requirements. Or you could use thin pure silver wire. DC can safely be run parallel. No need to X cross the wire. But if the power is pulsed or has an AC component then braiding in an X (90 degree) fashion would lower the cross talk but it will lengthen the wire. (Right-Hand Rule.) Short runs of parallel are usually ok. |

I'll test the result on one drive & report back in 2 weeks. |
