Wire Gauge. The specifications recommend 16 AWG or larger stranded copper wire for the power bus wires and 24 AWG or larger for the track feed wires. 16 AWG is also recommended for the AC accessory bus (if used).

Basic wiring schematic drawn using XTrackCAD:

Wiring allows for a specific DCC local control input. The recommended Anderson Powerpole red connectors are being used for the Power bus. The Anderson Powerpole black connectors will be used for the AC Accessories bus (16v AC) when installed. The red connectors are stacked as a vertical pair and the black connectors are joined as a horizontal pair.

You can get a packet of a single pair of Anderson Powerpole connectors from the Jaycar stores. I required quite a few and I got my Anderson Powerpole connectors in a 10-pair pack from an ebay store located in Melbourne. The pack consisted of 10 Red and 10 black housings and 20 contacts to suit:
Power Bus
Power wiring of the middle section module is shown below. The socket for the specific local DCC controller is at the bottom left as is also the station track isolator switch (when DC mode is used).
Wiring will be completed and track operation tested before any track is permanently tied in position. Full operational running will be carried out before any ballasting is considered.

Command Bus
The DCC Command cable has been installed with RJ12 6p6c mounted sockets used to enable connection across module sections using a 'jumper cable'. The RJ12 6p6c cables are 'straight through' wiring.
The number of RJ12 6p6c mounted sockets installed will depend on the number of wireless throttles likely to be used.
The picture below shows the Power bus and the Command bus being connected across one of the interfaces.
