What does this mean Current density of copper bussbars shall not exceed 1000 amperes per square inch I know it's self explanitory but would be the problem if the current density was too high?
Well as you said, it is self explanatory. The current density should not be more than 1000 A per square inch roughly coming to about 1.6 Ampere per square mm. Consider the case when the current density is high i.e. it could be high because of either reduced area with same current OR with more current through same area. Any of this case would lead to increase in the thermal lossess which could eventually lead to thermal runaway without the temperature rise getting stabilized (Stability being defined as temperature rise not exceeding 1 deg C per hour).

What is the current in 1KVA Transformer?
Tis question is incompleet.1000 va =1 kva.This is the power capacity of transformer. A transformer having 2 currents Primary current and secondary current . for that we required both voltage. Simply we can calculate by a formula Voltage x Current x 0.8(power factor)=1000.
How do you increase current capacity of an ammeter?
In measuring high AC currents a current transformer with a suitable rating say 100/5 or 1000/5 are used. The secondary current is usually 5 amps when the fulload current of 100 or 1000 as the case may be is flowing in the mains. It is the univerasl practice to use CT's for measurement of AC currents. In DC circuits the transformer method will not work, so to increase the current that you can measure you can allow a known amount of current to bypass the ammeter and recalibrate the ammeter. In other words, put a shunt in parallel with the ammeter.
How do you calculate DG set current?
To calculate the DG set current, you need the load current and the load voltage. To convert it into kilowatts it is divided by 1000.
What is the weight of 400 mcm copper wire per foot?
500mcm 37 strand copper wire = 1.544lbs/ft.
Why a transformer is rated as KVA?
A transformer has separate ratings for voltage and current. The voltage limit is set by the maximum magnetic flux-density in the iron core. The current limit is set by the resistance of the copper wire in the windings. Multipy the two together to get the VA rating, divide by 1000 to get kVA.

If something is compact what is its density?
Copper has a density of rho = 8950 kg/m3 = 8.95 kg/dm3 = 8.95 g/cm3. Water has a density of rho = 1000 kg/m3 = 1000 g/L = 1.000 kg/dm3 = 1.000 kg/L = 1.000 g/cm3 = 1.000 g/mL Helium has a density of rho = 0.1785 kg/m3 = 0.1785 g/L = 0.0001785 kg/dm3 = 0.0001785 kg/L = 0.0001785 g/cm3 = 0.0001785 g/mL. In this example: Metal has a density of 8950 kg/m3. Liquid has a density of 1000 kg/m3. Gas has a density of 0.1785 kg/m3. The metal copper is compact.

How many liters in 1000 kg?
A litre is a unit of capacity. A kilogram is a unit of mass. Without some unit of density to convert, the two units are incompatible.
What is he towing capacity of a 2009 Acura TSX?
The towing capacity of Acura's ranges from 1000-5000. The TSX has 1000 pound towing capacity.
How do you calculate zinc anode quantity in water ballast tank?
current= area of surface x current density required / 1000 , weight of zinc anode = current x life of anode (4yrs) x 8766 / 780
What does the density of water have to do with measuring of density?
density of water is taken as primary density as u can see it is taken as 1 1000
What is a metric unit of capacity or volume that is equal to 1000 millimeters?
There is no metric unit of capacity or volume that is equal to 1000 millimeters. This is because millimeters is length, and it has no relevance to capacity and/or volume.
What is the standard unit of density?
Unit of density is 1kg/1000 cm3 because Density = Mass/Volume
How does the phrase of water affect its specific heat capacity?
It is because the density increases as you add salt and with all other substances the higher the density the lower the specific heat. For example water has a density of 1000 Kg m -3 and a specific heat of 4186 J/Kg. On the other hand copper has a density of 8960 Kg m -3 and a specific heat of 385 J/Kg.
