Sub distribution board wiring:

This diagram shows how to make sub-distribution board wiring. In this circuit, we use an SPD ( Surge Protection Device ), some DP MCB ( Double Pole Miniature Circuit Breaker ), and an RCCB ( Residual Current Circuit Breaker ). Here we need to connect the SPD with the power source. Then connect the DP MCB with the SPD, then connect the RCCB with DP MCB, then connect all DP MCBs with the circuit.

Components used to make the Sub distribution board wiring:

01. DP MCB:

DP MCB In 2 Pole MCB, switching & protection is affected in phases and the neutral. A Double Pole or DP Switch is a Switch that Controls 2 Circuits at the same time. In terms of Residential Switching, this Normally means it Switches the live and Neutral at the same time. In Layperson Terms, Double Pole switches or DP Switches are Exclusively Designed to Control 2 Different Electrical Circuits at the same time, which allows the Appliances to Isolate safely and reliably. Fan or light Combinations and Medical Equipment are some of the many applications for DP Electrical Switches and Electrical components.

02. SPD:

The ability of an SPD to limit overvoltage in the Electrical distribution network by diverting the surge current is the surge-protective component, the mechanical structure of the SPD, and the connection to the electrical distribution network. A surge protection device SPD is a component of an electrical installation protection system. This device is connected to the power supply in parallel with the load circuit it is intended to protect. It can be used at all levels of the Power Supply Network. It is widely used in overvoltage protection.

03. RCCB:

The Residual Current Circuit breaker RCCB is the Safest device to detect and Trip against Electrical Leakage current. This ensures protection against Electric shock Caused by indirect contact. Circuit breakers (CB) are automatically Operated Electrical Switches that Protect Electrical Circuits from Short-Circuiting or Overloading systems. It Protects against many major accidents. RCCB Circuit Breaker is an Electrical Wiring device whose function is to disconnect the current in the circuit.

Frequently asked questions

What is sub-circuit wiring?

Subcircuits are self-contained circuit diagrams that appear as "black boxes" in other circuit diagrams. A given subcircuit may be used more times at multiple levels just as long as it does not become a subcircuit diagram of itself. There are 3 types of subcircuits: cards, chips, and plug-ins.

What is a sub-main switchboard?

A sub-main panel acts as a type of intermediary between the circuit diagram that is part of the main panel and the property. They may include additional subpanels and connect directly via a special type of circuit diagram feeder and also come with a breaker.

What is a distribution switchboard?

A distribution switchboard is a point at which an incoming power supply divides into separate circuits, each of which is controlled and protected by the fuses or switchgear of the switchboard

What is the final distribution board?

A final distribution board (FDB) is an assembly of protective devices, including 2 or more fuses or circuit diagram breakers, arranged for the distribution of electrical energy to the final circuit diagram.

What is a 3-phase distribution board?

Three-phase distribution boards are panels that house the circuit breakers, ground leakage protection units, and fuses that are used to distribute power supply to individual consumer points or circuit diagrams within a building.
