This is my bus header it has a phone jack to plug into the DCC booster and screw connectors for the wires.
This how I wired the DCC control bus on my On30 layout. It requires no crimping of connectors. I have done that for computer networks and wanted a simpler method. All the materials are readily available in home improvement stores.
I use these outlet plates they are 6-conductor.
Round 6-conductor phone wire
I put my outlets in these locations.
Make a cardboard template to mark the outlet cutouts. It has to have minimal clearance where the holes are at the arrow. The card board is the width of the sideboard.
I used a rotary tool to cut the holes. Make sure to use the general purpose bits, the drywall bits smoke, turn blue and make you wonder why you bought the tool.
Mark the outlet cutout with the cardboard template and cut it out.
My maiden voyage with the rotary tool, it takes a while to get used to the cutting.
Mounting the Power Station and Bus Header
Make a mount for the power station, mine is 1x4's and 1/4" luan plywood. Connect the power station to the power bus with 14 gauge power wire jumper. Screw the bus header to the power station mount, and connect the wires by color code.
DCC bus outlet plate wiring
The outlet plate has to sets of wires. The bottom wires are connected to the top outlet. Do this when you start to connect the DCC bus wire.
Some of the outlet plates have more holes move the top screws down and clip of the excess ear.
Connect the wire to the outlet plate moving the lower wires to the upper outlet and connect the bus wire. Start from the circled post and move upward.
This how a finished outlet box looks. Continue around the DCC bus connecting the outlets. Test the bus after finishing each outlet.
