The term, 'busbar', is derived from the word, 'omnibus', meaning 'to serve all' (the commonly-seen spelling, 'bussbar', is incorrect). A busbar, then, is a length of conductor, of suitable cross-sectional area, to which a number of common circuits can be connected. In a substation, Transformers often energise busbars to which many circuits can then be connected.
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.
Bus coupler is use to separate the main bus and reserve bus bar while the bus tie is used for paralleling and syncronizing.

Single bus is used in smaller, less important substations. A fault on the bus requires tripping of all lines into the bus. When higher redundancy is necessary, ring and breaker and 1/2 schemes are used. These are the three most common.
To check bus bar contact resistance, use a micro-ohmmeter capable of measuring low resistance values accurately. First, ensure the bus bar is de-energized and properly isolated for safety. Connect the micro-ohmmeter leads to the bus bar connections, and take the measurement. Record the resistance value and compare it to the manufacturer's specifications or industry standards to determine if the contact resistance is acceptable.
The term "bus bar" refers to a strip of bar of brass, aluminum, or copper. This strip of bar conducts electricity with a distribution and switch board.
Its a switch
Most busbars are copper with a tin plating to protect from corrosion.
Bus bar is a physical component that carries the current. AMP is unit of current. They can not be converted
...because it is an infinite bus bar, meaning it can supply infinite current. By Ohm's law, since the voltage at the bus bar is fixed, to have infinite current, you must have a zero impedance.
The primary difference between a 200 amp bus bar and a 150 amp bus bar lies in their current-carrying capacity. A 200 amp bus bar can safely handle a maximum load of 200 amps, making it suitable for larger electrical systems, while a 150 amp bus bar is limited to 150 amps. This difference affects their applications; a 200 amp bus bar is typically used in larger service panels or commercial settings, whereas a 150 amp bus bar may be adequate for smaller residential systems. Additionally, the physical size and material specifications may vary to accommodate the different current ratings.
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
