How to calculate the BusBar size?

Thread starter megatronic
Start date Feb 22, 2009

AI Thread Summary

To calculate the busbar size for a distribution panel with an 800A interrupting capacity and 50 kA at 320V/220V, engineers should consider factors such as current-carrying capacity, temperature rise, and short-circuit ratings. The appropriate busbar size can be determined using formulas that account for these parameters, ensuring safety and efficiency. Resources like the provided iPaper can offer detailed guidance on busbar design principles. Proper calculations are essential to prevent overheating and ensure reliable performance. Accurate sizing of busbars is crucial for effective electrical distribution systems.

can any engineer show me how we can calculate the busbar for any distribution panel assum that we have 800A interrupting capacity 50 kA, 320V/220V

also, if we make an calculation how can we determain the apprperat busbar.
thank you

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
