Voltage Drop Calculator
Check voltage drop, maximum distance, maximum amperage, and recommended conductor size for Canadian electrical runs.
Inputs
Enter the basic run details. Advanced settings are handled automatically unless you want to fine-tune them.

Calculation Details
Voltage Drop Notes
One-Way Distance
Enter source-to-load distance. The calculator applies the return-path or three-phase multiplier.
Default Settings
Defaults use 0.90 PF, steel conduit, 90 C, and one conductor set for a conservative estimate.
Recommendation
The recommended conductor is based on voltage drop only. Ampacity and code rules must still be checked.
Field Estimate
Actual results can vary with conductor condition, temperature, terminations, harmonics, installation details, and local code requirements.
Disclaimer
This calculator is provided as a general estimating tool only. Results are based on simplified assumptions and available impedance data. It does not replace engineering review, manufacturer data, the Canadian Electrical Code, local amendments, or approval by the authority having jurisdiction.
