1 - PDB- Power Distribution Board:

Distribution board is used for controlling of utilization of power in the end point like as lighting circuit, power circuit and other equipment like as TV, fridge and airconditioning.
The incomer supply is received from distribution panel. In this board, balance load is distributed as phase wise.

2 - Connection Diagram of PDB:

3 - Components of EDB:

PDB is the group of electrical parts where TPN MCCB is used for incoming and RCCB, ELCB are used for phase protection. Single phase MCB is used for lighting and power circuit.

1- Distribution Board Body:

PDB is available in market different different types size and model like as single phase and three phase.

2- Power Incoming Supply Source:

TPN- Three phase neutral MCB

Three phase neutral MCB are used for three phase and double pole MCBs are used for single phase incoming supply from distribution panel. What is the MCB , working principle and connection diagram?

3- Out going supply source:

1- RCCB- Residual case circuit breaker

RCCB is used for protection of current leakage in all phase like as R,Y and B phase. It work on current leakage function. Generally it available in market as 30ma, 100ma, 300ma. etc.
What is the RCCB , working principle and connection diagram?

2- ELCB- Earth leakage circuit breaker

ELCB is used for protection of earth leakage in all phase like as R,Y and B phase. It works on voltage basis. Generally it available in market as 30ma, 100ma, 300ma. etc. What is the ELCB , working principle and connection diagram?

4- Neutral Link:

Neutral link is used as neutral terminal where all circuit neutral wire is connected. Neutral link is the important part of electrical system which is used for terminating of neutral wire for every circuit. Neutral link is made with metal parts which have many terminal point for neutral distribution.

5- Earthing Link:

Earth link is used as earthing terminal where all circuit earthing wire is connected. Earthing link is the important part of electrical system which is used for terminating of earthing wire for every circuit in distribution board. Earthing link is made with metal parts which have many terminal point for earthing distribution.
