Technical Recommendation
The selected cable size appears suitable for the entered load and cable length based on the allowable voltage drop.
TECHNICAL CALCULATOR
Voltage Drop Calculator
Check estimated voltage drop for a selected cable size using load current, cable length, conductor material and published voltage drop values.
Cable Design Estimator
Voltage Drop Calculator
Technical Reminder
Voltage drop is calculated using the selected cable type's published mV/A/m value directly. Other calculators may differ if they use impedance, conductor operating temperature, reactance, cable construction or a different wiring standard. Final cable sizing must also consider current-carrying capacity, installation method, grouping, ambient temperature, fault level, protective device coordination and SANS 10142 requirements.
