The wire gauge a DCC bus needs at every common length and current, the voltage drop it produces, and how many feeder drops the run wants.
Every page here is computed rather than written, so the figures match the calculator that produced them exactly. Where a figure is a hobby rule of thumb rather than a published NMRA standard, the page says so. Every table is plain HTML you can quote.

Eight amps with auto-reversing built in, which is what a reversing loop needs to avoid a short every time a train crosses the gap. It is a booster only and needs a command station.
Best for: adding current and a reversing loop to a Digitrax layout

Selectable 3, 5 or 8 amp output, so one booster suits N scale or large scale. Setting it higher than the layout needs is not a benefit: the current has to go somewhere in a fault.
Best for: a booster that matches the scale it is powering

Feeder wire in the two colours you need, tinned and silicone jacketed so it stays flexible and takes solder easily. Red and black on a spool each removes a whole class of wiring mistake.
Best for: track feeders

A third colour, which is what you want for accessory and turnout wiring so it is never confused with the track bus.
