Bus bar is a conductor used for power transmission in the
panel in which various number of tappings ( i.e power
source) can be drawn. It can be of Aluminium or Copper .It
will be in flat size.

Answer / a.ramaprasd

The live conductor provided with a panel /switch
boards /ower distribution boards/ bus bucts & rising
mains are known as Bus bars.

Normally these are made up of Cu or Aluminium.They are
solid materaial normally in a rectange ed flat size of
different dimension based on the amount of current it has
to carry.

Why it is called as bus bars it is a question.

Bus is a one which transports men and material from one
place to other. Now that these bar transport power from
one place to other they may be named so.

some had aid in olden days the buses and trams which
transport people had a a continious holder at the celing
leval of the bus for men to hold were made up of Alu or Cu
bars , which were looking like thse bus bars.

from one place to another place ) in which more number
tapping are taken out according to usage.

Answer / latika

Ramprasad's answer is a nice new idea which reasonably
appears to be the correct answer. Thanks for the idea.

Answer / ranjith

multiple circuit connected to single conductor or
alluminium rod

Answer / s.karthik

I agree with you ram to some extent.

i have visited some power generating stations where the bus
bars are made of thick hollow spherical copper or aluminum
conductors.

Reason being that AC always has the tendency to flow on the
outer surface of the conductor which we call the skin effect.

I have seen rectangular strips too but not on the generating
stations but on the panels.

donno the exact reason behind

When testing an earthing connection, we use a 60 or 100 candle bulb with a phase connected direct from supply and the other wire to the new earthing provided.If the bulb glows then the earth is ok.Else earth connection is not Ok. So, why dont we can use all the home appliances taking a single wire from the phase and the return connection to Earth instead of return connection to neutral?
