To ensure safe operation and work on full load without being damaged cable sizing calculation is very important. It helps us to provide suitable voltage for the load.Besides this proper sizing help us to withstand the worst short circuit current, and ensure device safety during operation.
In this article, we will discuss methodologies and other related parameters regarding cable sizing calculation. And of curse we will give a simple example to choose a cable.Cable Sizing Calculation StepsThe process of the size calculation method consists of six steps.In the very first step, we collect data about cable, load, and environmental conditions.The second step is to determine the minimum cable size for continuous current carrying capacity.The next step is to determine the minimum size of the cable based on voltage drop.Determine the minimum size of cable for short circuit conditions.The fifth step includes determining the minimum size of the cable in case of earth fault loop impedance.The final step is to select the minimum size of cable in the previous steps.I have created an android app to help you in selecting cables, The app is 100% FREE, it has the most common cables tables. Such as current ampacity tables, short circuit tables, derating factors tables and more. These tables are simple in design to make it easy for you to use it. I will be happy if you install the app from here.
I never like memorizing this stuff and carrying cable catalogs every where.So I created my own simple custom android apps to help myself. It feels great that I have my solution!Then, I published these apps, 100% FREE, on the google play store, to help you at your work. Install the apps, No Fees, No credit card needed.Cables tables cables most used tables, I use this one all the time.Fast Electrical Calculator App, the one I use for electrical calculations, I always count on this baby the most.Motor Calculator App is a simple app for electrical motor calculations.Cables Ampacity Tables App we need cable ampacity almost every day, in this app, I made it easy for you to check cable ampacity.Circuit breaker Selection App This one is a fast way to determine circuit breaker sizing.I will be happy if you use one of them, share it, and rate it on the market. This way you help me continue updating the apps. 2b1af7f3a8
