copper bus bar,sqmm X 1.3times, aluminium means sqmm X 0.8 times.. but cable wise dont know can any1 tell me..
There is actually no specific formula used to work out cable size. In order to determine the type of cable you need and the size you need, you need to know the source of the supply, the voltage of the system, the ambient temperature, and the method you plan on laying out the cable.
how to know dc cable sizes
closing stock calculation formula? closing stock calculation formula? closing stock calculation formula? yes how can i do the closing stock calculation?
1) determine load /design current. eg 13kw oven Ib=13000W/230V if 3 phase- 13000w/1.73*400V =56.52A In(circuit breaker size)=60A 2) In/ C1+C2+C3 (c is coefficient of ambience temperature of type of cable referred to BS tables) 3) value of above refer to BS tables for appropiate cale size. eg. based on 60A cable size is 16mm2 pvc/pvc cable size
The concept of sample size calculation has evolved over time, with contributions from various statisticians. However, key developments in the formula for sample size calculation can be attributed to statisticians like Jerzy Neyman and Egon Pearson in the 20th century, who formalized concepts related to hypothesis testing and estimation. Their work laid the foundation for modern statistical methods, including sample size determination.

To calculate the cable size for a 100 kW load, you would need to consider factors such as the voltage of the system, the type of cable insulation, the ambient temperature, and the installation method. The cable size is typically determined by the maximum current the cable will carry without overheating. Using the formula: Cable size (mm²) = (2 x L x I x R) / (√3 x V x cosΦ), where L is the cable length, I is the load current, R is the resistance of the cable, V is the voltage, and cosΦ is the power factor, you can calculate the appropriate cable size for the 100 kW load.
