2.5An easy to use cable calculator to calculate the required cable sizes for various cables types, installation methods, correction factors and protective devices to BS 7671 18th edition version. Calculates cable size, r1+r2, volt drop %, and determines what the expected Zs value will be. Carry out on the spot instant cable calculations, great for electrical surveys, condition reports, circuit design and cable sizing on the go. Features: - Print, Save, Email & Share the cable calculation results PDF (from the print function) - 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 This cable calculator also checks the volt drop %, max Zs, R1+R2 and applies the relevant correction factors from an easy to use selection list of options. How to share or email the cable calc results PDF file: 1) On the Results screen tap "Print". 2) Expand the displayed image (preview window is then displayed). 4) Tap the share icon to show your device's share and save options. Calculate circuit cable sizes for final circuits, distribution circuits and sub main electrical supplies. This cable sizing app 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 cable calc 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.
