I'm working on writing up a wiring schedule for the purpose of buying multiconductor and shielded cables. Reading through various installation manuals I see many signal cables with shields, which I would expect to see.
I would also expect to see shields on power wiring for some items, but they're not called out...for instance the GSA 28 autopilot servos don't show shields on their power/ground wiring.
I know there are recommendations out there for shielding certain types of wiring like strobes and that wiring in the vicinity of, e.g., magnetometers should be shielded.
Are there general recommendations for shielding power wiring to devices? I'm not seeing them in AC43-13, but may be missing them.
I do intend to return power ground wires back to a common ground bus, or in some cases a local ground terminal block that is in turn gorunded to the main ground bus. Should these be shielded?
I've also seen some recommedations for using twisted pairs for power wiring running near sensitive devices.
Are there some solid best practices out there that people can recommend? I don't want to add weight unnecessarily, but don't want to have to revisit wiring once it's pulled, either.
