ELcalcZs Pro is an Electrical Calculator App,
That can be used to calculate the Resistance
of The Conductor Cable and The Earth Cable
(R1 + R2), and Earth Fault Loop Impedance (Zs)
for a new electrical installation.
This is Necessary for determining whether the
circuits protective device will operate within
the correct time limit,
Due to the fault current generated by the
resitance of the circuit.
Works for copper cables up to 1000mm.
Allows you to select ambient temperature,
and apply correction factors for cable type.
Complies with BS 7671 : 2008 17th Edition.
