What size wire should be used to cross connect the -ve between two (or more) power supplies ?
In theory, there shouldn't be anything flowing between them as the reason it exists is to provide a return path for the Data signal, but .....
And the associated question - is there a reason to put a fuse on the connection ?
I know, you fuse all the positive side, and in general you use a fuse to protect the cable, so in the case something goes wrong, is it a good idea to protect the cross connection ?
