Such an arrangement of two incoming lines is called a double circuit. Both these lines can be loaded simultaneously to share the sub-station load or any one line can be called upon to meet the entire load. When discussing low-voltage power distribution systems, many people assume that “two incoming lines with a bus coupler” and “dual power supply” are mutually exclusive options. In practical power systems, these configurations can coexist within the same. The Distribution box system diagram mainly includes the following parts: Incoming line part: Displays the incoming line source of the distribution box, which may be a single-line incoming line or multiple-line incoming lines (such as normal power supply and backup power supply), and marks the. The Key Diagram of Substation can be explained as under: 1. to shape up your technical skills Hi, I'm an electrical engineer, programmer and founder of. A distribution board, also known as a DB box, is like the central hub of an electrical system.
