NCE recommends twisting bus wires about three turns per foot. I use
DCC with my old DC wiring, which has about six turns per foot.
In connection with DCC I haven't heard of any issue regarding
inductance, which I understand is the magnetism created by the 15
volt AC current.
Number 14 gauge wire is satisfactory for runs to fifty feet, again
according to NCE.
Gratuitous advice: When experts have different opinions, do what
makes sense to you.
