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 MCCB's & ACB's (max Zs)
✔ Support for RCD's in TT Earthing Systems
Design 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 fuses
Cable 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 it's cable sizing calculations:
- Vd : Max volt drop
- Cf : Correction factors
- L : Length of circuit
- Zs : Maximum Zs 80% temperature adjusted value
Example Verification Checks:
- Checks the calculated Zs with the Max Zs 80% value
- Checks if user selects TT earthing system = RCD required
- in="">
- Checks if user selects disconnection time 5 seconds and device In =
