Bus bar is Aluminium or copper flat/strip installed inside
any panel for carrying current. Incomming suply comming
into the panel through incomer (VCB/ACB/MCCB/MCB/Isolator)
and connected to this busbar. To this busbar all outgoing
feeders are connected via breaker.
The busbar may be in LT or in HT panel.

Answer / victorvgp

First of all Busbar is a bar conductor having comparitively
higher thickness in order to neglet I(square)*R losses.

The purpose of placing busbar is to maintain constant
voltage to all parallel circuits connected throughout the
panel.

Answer / selvakumar.v

it will carry the rated current contuniously

Answer / minal

High current carrying conductor to which the breakers are
connected in panels is called busbar.

Answer / kriti ranjan

Busbar is a strip or bar of copper, brass or aluminium that conducts electricity within a switchboard, distribution board, substation, battery bank or other electrical apparatus. Its main purpose is to conduct electricity, not to function as a structural member.
The cross-sectional size of the busbar determines the maximum amount of current that can be safely carried. Busbars can have a cross-sectional area of as little as 10 mm2 but electrical substations may use metal tubes of 50 mm in diameter (20 cm2) or more as busbars.

Answer / sushant

Bus bar means Cu-Patti. It Carrying A High Current With
constant Voltage.Bus bar Used in l.T panel.

Answer / harithejas

Busbr is an electrical conductor material (copper or
aluminium), suitably sized to carry specified currents both
thermal and short circuit for a defined time, supported on
insulators or surrounded by insulation materials, used to
make common connections between many circuits or
interconnect incoming power supply and outgoing feeders.
The shape of busbar material can be any, but videly seen
are rectangular, circular tubes, wires etc.

Answer / ranjith

Point at which electrical power is available for
transmission.

Answer / sandip singh

it is solid or hollow tube strips or rod of cu or al. which actually collected the power system parameters and then the transfer the parameter to the direction as per arrangment
