Basic Composition Of Distribution Box System Diagram
The Distribution box system diagram mainly includes the following parts:
Electrical parameter description: Equivalent to the electrical nameplate, it provides basic electrical information of the distribution box, such as number, rated power, required coefficient, power factor, calculated total active power and calculated total current, etc.
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 model and rated breaking current of the incoming line circuit breaker and other information.
Dual power switch (if applicable): In a distribution box with dual incoming lines, it is used to automatically switch to the backup power supply when the normal power supply fails.
Outgoing line circuit: Displays the outgoing line circuit for the distribution box to supply power to each load, including busbars (if any), outgoing line circuit breakers or fuses, load equipment, etc.
