How this calculator works
Provide circuit length, current, voltage, and conductor details. The app returns expected drop so you can decide if upsizing or shortening runs is justified.
CE Code alignment
The tool supports Canadian electrical design practice for voltage drop review. Always confirm the limits and methods required by your project specification and AHJ.
Run in the app
Sign in to run the voltage drop calculator, save runs, and export PDFs.
FAQ
- What is a CEC voltage drop calculator?
- It estimates voltage drop on feeders and branch circuits using conductor properties and load current so you can compare results to common Canadian design limits and document wire sizing decisions.
- Does the calculator support copper and aluminum?
- Yes. You can model conductor types used in Canadian installations and compare outcomes for long runs, high current, or mixed material choices.
- Why do electricians care about voltage drop?
- Excessive drop can affect motor torque, lighting levels, and sensitive equipment. Documenting expected drop supports code-consistent design and reduces callbacks on longer feeders and branch circuits.
