All: I’m adding to my last prior post here to provide more context to the Canare Starquad story and their wiring scheme. As one can see from their wiring diagram, their 2 hot conductors are sliced together in parallel. Likewise, their 2 return conductors are spliced together in parallel. Note one common shield element, however.
