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 volts 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
