calctricFrom input to answer.
- Set the region to Canada and open All Tools → Ground & Bond.
- Choose the actual purpose, such as Circuit bonding.
- Select conductor material and enter the protection, service or other basis requested for that purpose.
- Review applicable installation options and the result details. Confirm that the displayed basis matches your system.
WORKED EXAMPLE
A circuit-bonding check
Enter
Select Circuit bonding, copper and a 200 A protection rating, without additional upsizing or parallel-run adjustments.
Read the result
The example returns 6 AWG copper. The basis is the selected circuit-bonding case; it is not a universal grounding-electrode conductor size.

- Grounding and bonding purposes use different inputs. Select the purpose before entering a rating.
- Review extra options for parallel sets, voltage-drop upsizing or transformer arrangements only when applicable.
Know the limits.
- Canada-mode CEC 2024 supported cases. Connections, routing, continuity, mechanical protection and local amendments are separate checks.

Common questions.
Can I use one answer for every ground wire?
No. First identify the conductor’s function and the applicable sizing basis.
