Cable size calculator - Calculate final circuit & sub main cable sizes with ease
Features Cable Calculator
Cable Size Calculator for Android.
Calculate the minimum required cable size for various cable types & sizes, protective devices, installation methods and correction factors.You can use this cable calc app to check existing installed cables and circuits for compliance to verify existing cable sizes in existing installations or for designing new final circuits and sub main supplies in new installations.Features:
✔ Print cable calculation results
✔ Verification and validation checks
✔ Support for manufacturer specific MCCBs & ACBs (max Zs)
✔ Support for RCDs in TT Earthing SystemsDesign Parameters:- Ib : Design current (Amps)- L : Circuit length (Meters)- Vd : Maximum permitted volt drop (%)- Uo : Supply voltage (Volts)- Ze/Zdb : Supply source earth loop impedance (Ohms)- In : Protective device rating (Amps)- s : Maximum disconnection time (Seconds)- Cable type- Installation method- Protective device type- Earthing system type (TN-C-S, TN-S, TT)Correction Factors:- Cg : Grouping- Ca : Ambient air temperature- Ca : Ambient ground temperature- Ci : Thermal insulation- Cc : BS 3036 semi-enclosed fusesCable Calculator Calculations:- It : Tabulated current- R1+R2 : Circuit expected R1+R2 value- Zs : Circuit expected Zs value- Max Zs : Calculated max Zs values for 0.2s, 0.4s & 5s (80% + 100% values)- Vd : Calculated voltage drop %- CF : Total applied correction factor value- Minimum required cable size (mm²)This cable calculator takes into account and applies the following factors for its cable sizing calculations:- Vd : Max volt drop- Cf : Correction factors- L : Length of circuit- Zs : Maximum Zs 80% temperature adjusted valueExample Verification Checks:- Checks the calculated Zs with the Max Zs 80% value- Checks if user selects TT earthing system = RCD required- Checks if user selects 3% volt drop (lighting) and device In = >16 amps- Checks if user selects disconnection time 5 seconds and device In = <32 amps- Checks if selected protective device Max Zs already exceeds your supply Zs/Zdb value- Checks if design current (Ib) exceeds the protective device rating (In)- Checks if the protective device rating (In) is double the design current (Ib)- + many more...A great cable sizing tool which also calculates the expected Zs value, volt drop %, and estimated r1+r2 in addition to the minimum required cable size.
How to use:1) STEP 1 - Enter your cable calculation design parameters2) STEP 2 - Select an installation method & apply any relevant correction factors3) Tap "Calculate" to calculate the cable size4) Tap the printer icon to Print cable calculation results5) Optional, sign the screen to sign the documentThis cable size calculator app is designed for Android phones and tablets.

What Our Users Say
Don't just take our word for it. Here's what our users have to say about our Android app.
"Asks for too much data before calculating. It's very difficult to calculate the initial cable size, as it asks for way too much data. For example, it asks for Ze(Impedance) and Protective device rate, when it is not needed. For example, I simply run cable from transformer to the building electrical panel. If you simply need to calculate size of the cable based on kW or Amp total, all these data is not necessary and not needed. The other application from Ettoire Group is much better."

"Shame you can only have a cable with same size cpc as live conductor, especially when using swa and want to run a different size separate cpc."
Pete Blaney
"Nice easy to use calculator, would be nice if you could add a separate CPC for distribution circuits but not a deal breaker."
Malcolm Craik
"By far the best I have used."
Sam Watson
"Good report"
