Because copper is a very good conductor of electricity. Most other metals aren't as good, and would cause more resistance, resulting in the bus bar heating up.

What are service panel bus bars?
Typically copper conductors that provide a phase of electricity.
What tests need to be carried out when commissioning bus bars?
Bus bars need to be meggered to make sure that there is no shorts between the bars and from the bars to ground. Usually electrical engineers have a list that has to be checked off and values written down before any energizing of the equipment will be allowed.
Why do we use bus bars in electrical system?
Bus bars are used in Motor Control Centers (MCC) and high voltage switch gear. These copper bars are used in place of wire that would be hard to bend and fit into tight cabinet spaces. The copper bars are easily formed into odd shapes toaccommodate connections of the incoming power source to internal equipment. The bars are easily extended if another section has to be added on for future expansion. In an MCC, if more motor sections are needed the new panel is just bolted to the old bus bars for a continuation of the power to the new section. Because of the amperage of some equipment, single wire just does not have the capacity to handle the current.
The purpose of the bus bar protection unit is to isolate any bus by tripping its contactor or isolate a faulty bus in the variable ac system?
The Bus Bar is (usually 3, or 4) solid copper bars that run through an MCC (Motor Control Center) and just supply power to the individual 'buckets' (compartments that contain the individual motor starters). The only protection for a bus bar would be from the 'Panelboard', or 'Switchboard' breaker that feeds the bus bar mounted in a separate MCC. Make Sense???, let me know if not...
What is Bus bar electrical?
A bus bar is a solid copper or aluminium bar that is used in switch gear and motor control centers. Smaller bus bars are used in central distribution panels and seen in everyday use, the bars that the household breakers plug or bolt into in a homes distribution panel. The bars in switch gear and MCC's are rated to carry a rated current. To bend a wire into the back of these types of equipment would be next to impossible due to the constraints of limited space.Additional InformationThe word 'busbar' is derived from the word, 'omnibus', meaning to 'serve all', which is exactly what a busbar does -it serves all the circuits connected to it.Occasionally, you see the word, 'busbar', spelt as 'bussbar' -this is an incorrect spelling which indicates a lack of knowledge of the origin of the word.
What are service panel bus bars?
Typically copper conductors that provide a phase of electricity.
Difference between bus bar and bus duct?
Bus bars are actually simple conductor strips of copper using for connection between one system to another.for example transformer to panel. bus ducts are enclouser of that bus bar
What type of electrical equipment uses bus bars in its construction?
High current service entrance equipment and MCC (motor control centers) all use bus bars in their construction.

How do you make copper bars in Warcraft?
Using your smelt skill you get from purchasing mining you smelt the Copper Ore you get into bars at a ratio of 1:1
How do you carve a block of bronze in RuneScape?
Use copper and tin ore on a furnace.This bar can then be used on an anvil (when you have a hammer in your inventory) to make bronze items.

How can you calculate the copper bus bar according to the amp?
To obtain the amp of the copper bus bar, multiply the width of the bus bar by the thickness of the bus bar to obtain the current carrying capacity of the bus bar.
Why The Bus Bar use only Aluminum?
Most busbars are copper with a tin plating to protect from corrosion.
What is the difference between a 100 amp breaker box and a 125 breaker box?
The amperage capacity of the main bus bars and the connection of the main breaker to the bus bars.
