Bus Wire

Heavy gauge wire running beneath the layout that distributes power to track feeders.

Full Definition

Bus wires are the main power conductors running beneath the layout, typically 12-14 gauge for adequate current carrying capacity. Track feeders connect to the bus wires, which in turn connect to the DCC booster or power supply. Proper bus wire installation prevents voltage drop across large layouts.

Examples

•A 12-gauge bus wire can carry DCC power across a large layout without significant voltage drop
