What is the minimum wire requriements for the downleads and the bus wire using the digitrax system? We are presently building ourlarge club layout and at the stage of putting in the wire for our digitrax system. There seems to be a discussion going on amongst the members at to what the minimum requirement for the guage of wire that is to be used on both the down leads, which are going to be put in about every six feet ( two lengths of flex track) and the bus wire. It would be greatly appreciated to hear from the people that are already experienced in this department as I, and most of the members of the club, are not. Thanks in advance for your replys..Ron..
