Cable sizes and diameter
You have to trawl through the various tables in the regs to input the data so you have already carried out the cable sizing. It gives you the minimum earth size but there is a quicker method of finding that too! Granted its more crude but it works. It would be better if it gave you a good estimate of csa based on length, max circuit power, and install method. Plus a percentage for future expansion.
Not sure as to the point of this app, it requires the inputting of all the max Zs values for the protective device, the mA/m values for the cable etc. I thought the idea would be to save you the hassle of getting all that data together but instead it just acts a calculator? Somebody has gone to a lot of trouble for nothing?
Spot on your work is good and I will be having a great time with the application
It is easy to use
