Here’s how it works, for Single or Three phase cable calculations, simply…
Input: The Load current, Length of cable run and Voltage drop i.e. 2.5%
Select: Cable material, Method of installation and Circuit protection i.e. fuse/cb

Push the “Calculate” button to instantly see all your results showing the most economical compliant cable size including…

a: Cable size and capacity
b: Voltage drop in volt and percent
c: Maximum length of run
d: Fuse or Circuit Breaker size
e: Working Temperature
f: Fault level
g: Minimum trip current needed to comply with Earth loop Impedance test
h: Actual let through current
i: Maximum impedance values (Ze) and the actual impedance values (in ohms)
j: Total impedance values(Zs) for the complete installation (in ohms)
k: Touch Potentials

Now you can easily find cable sizes for every cable run in your installation resulting in massive savings in time and money.
