5-6x150 Cu. BUS BAR PER PHASE
...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.
You first have to find out what the load amperage is going to be and second, what is the working voltage.
150×10=1500 1500×8.96=13440 ÷1000 kg/meter 13.440
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...
To avoid accumulation of moisture.
Earthing busbar size
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.
You just Calculate Size of Bus bar which has been mentioned below:Example: Calculate Size of Bus bar having Following DetailsBus bar Current Details:Rated Voltage = 415V,50Hz ,Desire Maximum Current Rating of Bus bar =630Amp.Fault Current (Isc)= 50KA ,Fault Duration (t) =1sec.Bus bar Temperature details:Operating Temperature of Bus bar (θ)=85°C.Final Temperature of Bus bar during Fault(θ1)=185°C.Temperature rise of Bus Bar Bar during Fault (θt=θ1-θ)=100°C.Ambient Temperature (θn) =50°C.Maximum Bus Bar Temperature Rise=55°C.Enclosure Details:Installation of Panel= Indoors (well Ventilated)Altitude of Panel Installation on Site= 2000 MeterPanel Length= 1200 mm ,Panel width= 600 mm, Panel Height= 2400 mmBus bar Details:Bus bar Material= CopperBus bar Strip Arrangements= VerticalCurrent Density of Bus Bar Material=1.6Temperature Co efficient of Material Resistance at 20°c(α20)= 0.00403Material Constant(K)= 1.166Bus bar Material Permissible Strength=1200 kg/cm2Bus bar Insulating Material= BareBus bar Position= Edge-mounted barsBus bar Installation Media= Non-ventilated ductingBus bar Artificial Ventilation Scheme= without artificial ventilationBus bar Size Details:Bus bar Width(e)= 75 mmBus bar Thickness(s)= 10 mmNumber of Bus Bar per Phase(n)= 2 NoBus bar Length per Phase(a)= 500 mmDistance between Two Bus Strip per Phase(e)= 75 mmBus bar Phase Spacing (p)= 400 mmTotal No of Circuit= 3 No.Bus bar Support Insulator Detail:Distance between insulators on Same Phase(l)= 500 mmInsulator Height (H)= 100 mmDistance from the head of the insulator to the bus bar center of gravity (h)= 5 mmPermissible Strength of Insulator (F')=1000 Kg/cm2
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.
Panelboards are wall mounted, usually up to 1200A bus rating. Switchboard can be free stand with access from rear. Switchboard could have bus rating up to 6000A. In general switchboards are more expensive and has more features than panelboards.
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.
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.
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
voltage of incoming machine should be same as that of bus bar voltage
