How many devices does a three-level distribution box support
Each switch box shall connect to and control only one associated piece of electrical equipment (including sockets). After stepping down the voltage through the transformer's low-voltage side (0. 4kV), power distribution is achieved through three levels of distribution boxes: the main distribution board, secondary distribution boards, and tertiary distribution boards. Main Distribution Board Serves as the primary. Connects to end-use equipment via switch boxes, forming a three-tier power distribution system. A feeder usually begins with a feeder breaker at the distribution substation. This device makes sure power goes to big machines safely and quickly. Big buildings with many floors.

What does TTU mean in distribution network automation
Distribution Transformer Supervisory Terminal Unit (TTU) is used in power supply and distribution systems to monitor and control distribution transformers. Compared to FTU, TTU collects more data types. Data Transfer Unit (DTU), also known as a "data transmission unit, concentrator, converter, or repeater," typically functions as a router or gateway. It supports multiple industrial protocols (e., MQTT, IEC101, Modbus) for wired input and transmits data to remote locations via wired or wireless. FTU is a kind of intelligent terminal equipment for distribution network automation, which is mainly used in feeder automation system. It helps map real grid scenarios into a robust architecture, a realistic checklist and brand-ready component selections. DTUs are typically installed at conventional substations, outdoor small-scale substations.
