Cable size calculator to calculate the required cable sizes for various types of cables, installation methods, correction factors and protective devices. 18th edition version.
Carry out on the spot instant cable calculations, great for electrical surveys, condition reports, circuit design and cable sizing on the go.
Also checks the volt drop and max Zs and applies the relevant correction factors from an easy to select list of options.
The cable size calculator calculates the required cable size, r1+r2, volt drop %, PSSC, and determines what the the Zs value will be.
Calculate circuit cable sizes for final circuits, distribution circuits and sub main electrical supplies.
Can also be used to check the electrical cable ratings for different electrical installation methods to ensure existing cables or wires are compliant on existing installations for an Electrical Installation Condition Report (EICR) including volt drop and Max Zs.
You can also use this app to check existing installed cable sizes and circuits to check for compliance and to confirm the correct cable size for the type of cable, installation method and length of circuit has been selected and installed correctly.
+ Verification checks and helpful hints
+ Support for manufacturer specific BS EN 60947-2
(max Zs) MCCB's & ACB's
+ Support for RCD's in TT Earthing Systems
