Re: [Amel Yacht Owners] Shield Wire in NMEA 2000 Backbone

I don't have a direct answer to your question, but here is some information for you that may be helpful.
Shields are normally connected to the metal case of the devices that are connected by the NEMA wire, but, as you know, many device cases are not metal.
I would never connect a shield to a battery negative and never connect a shield to a case where the case is connected to negative because that negative cable will conduct RF from any device connected to the battery bank.
