Busway and Busbars | Legrand United Kingdom

The short answer is that the track busway system feeds the PDU within the rack. To put it in simple terms, think of your home’s electrical wiring. You have a ring circuit with multiple sockets that allow you to plug in devices. The busway system works similarly, where each tap-off point acts as a power outlet. This tap-off unit then feeds the PDU inside the rack, which subsequently distributes power to IT equipment like servers and switches.

Think of it as a multi-plug adapter inside the rack. Instead of plugging in multiple devices directly into the busway, the PDU helps distribute power efficiently across the rack’s IT load.
