Estimates, Not Guarantees
The current calculator applies standard electrical formulas under ideal, balanced, steady state conditions. It does not account for cable resistance, ambient temperature, harmonics, voltage variation, motor inrush, unbalanced loads, or the specific requirements of your local wiring code. Every result should be treated as an approximate figure, not a certified design value.
Not a Substitute for a Professional
Nothing on this site is electrical, engineering, or safety advice. Working on electrical installations can be dangerous and is regulated. For any real wiring, protection sizing, or safety decision, engage a qualified, licensed electrician and follow the rules that apply in your country or region.
Three Phase and Power Factor
Three phase results assume a balanced load and use the line to line voltage with the root three factor. Power factor values are entered by you and strongly affect the current. If you are unsure of the correct power factor or voltage reference for your system, seek professional guidance.
No Liability
Current Calculator and its authors accept no responsibility for any loss, damage, injury, or cost arising from the use of, or reliance on, the calculator or the content on this site. You use the tool entirely at your own risk.
