3 Phase Electrical Distribution Board DB Wiring Procedure
To
understand and wiring an electrical distribution board, first of all you have
to clear understanding about DB or Distribution Board wiring definition and systems
as per international and local standard.
Here you will find some basic idea about Distribution Board and its types.
Here you will find some basic idea about Distribution Board and its types.
What Distribution Board (DB) Is?
A safe electrical
system designed for a house or premises that included isolation switches, protective
devices, connecting of multiple cable circuits including their associated neutral
and earth conductors. Distribution Boards are normally following three (3)
types-
Main Distribution
Board (MDB):
The
Distribution Board which in generally receive incoming source of Low Voltage
(LV) from transformer secondary of customer or the distribution company’s
service outlets. MDB is the first receiving point (bus bar) from Transformer or
Distribution Company.
The MDB
may also be known as the ‘Consumer Unit’ where the main isolation device and
Protective Devices are integrated.
Sub Distribution Board (SDB):
The Distribution
Board which is supplied from the Main Distribution Board in a building and
which is used to distribute wiring and circuits within a selected area, e.g. floor in a multi-storey building.

Final Distribution Board (FDB):
The Distribution
Board which supplies to Final Circuits. From FDB power goes to switching board
from where switch uses for power on/off particular devices.
Wiring Accessories for 3 Phase Distribution
Board:
The Distribution Board or Fuse Boards usually contains
following three things to control and distribute electric supply
safely:
v DP or
Double Pole MCB as main switch or main isolator;
v RCD (also
DP) Residual Current Devices for safety;
v SP or
Single Pole MCB as Circuit Breakers and Fuses.
Double Pole (DP) MCB (The main switch or Isolator):
This the
main operating switch to control electric supply in the premises, to turn off
and on the electric supply immediately due to any emergency like electric
shock, fire or while working on main board. Multiple mains switch may use
if one have more supply units.
RCD- DP, Residual Current Devices:
Residual Current Device, (RCD) or Residual
Current Circuit Breaker (RCCB) is an electrical wiring device or switch that
disconnects or trip a circuit whenever it detects that the electric current is
not balanced between the energized conductor and the return neutral conductor.
Then instantly go safe mode disconnecting the electric circuit.

Circuit Breakers (CB)
Circuit
breaker is a device which switches on at normal condition and off automatically
electricity at any abnormal condition. Alternately we can say these are
automatic protection devices in DB that switch off a circuit if they detect a
fault. Circuit Breaker may be SP-Single Pole, DP-Double Pole and TP-Triple
Pole.
In the
wiring diagram shown that 3 phase Read-Yellow-Blue receiving from a MCCB, these
3 phases are feeding 3 individual DP-MCB isolator switches, all SP-MCB receiving
through a common RCCB-DP and feeding to final distribution board. Please check the
above 3-ph to 1-ph wiring diagram where 3 phase electrical distribution board
wiring procedure with accessories are shown details.
good, very helpful post.
ReplyDeletewe desire more like this
thanx a lot that was very helpful in clearing my doubts.
ReplyDeleteExcellent blog, good to see someone is posting quality information. Thanks for sharing this useful information. Keep up the good work.
