Grounding vs Bonding Terminology in Canadian Practice
Grounding vs Bonding Terminology in Canadian Practice reference with assumptions and boundary notes.
Reference boundary
Terminology reference only. It does not define a grounding electrode system, size bonding conductors, or decide installation acceptance.
Reference table
Compare plain-language grounding and bonding terms used in Canadian electrical safety discussions.
| Term | Plain-language use | Common context | Boundary |
|---|---|---|---|
| Grounding | Connecting a system or equipment point to earth for voltage reference and fault or surge context | grounding electrode, system grounding, surge reference | terminology only; conductor sizing and installation acceptance require current source and AHJ review |
| Bonding | Connecting conductive parts together so they remain at the same electrical potential | equipment bonding, raceway bonding, metal parts | terminology only; conductor sizing and installation acceptance require current source and AHJ review |
| Equipment bonding conductor | Conductive path intended to connect non-current-carrying metal parts together and back to the source path | equipment frames, raceways, enclosures | terminology only; conductor sizing and installation acceptance require current source and AHJ review |
| Grounding electrode | Conductive object or system in contact with earth as part of the grounding system | ground rods, plates, concrete-encased electrodes | terminology only; conductor sizing and installation acceptance require current source and AHJ review |
| Bonding jumper | Conductor or fitting used to bridge around a discontinuity or join bonding paths | service equipment, raceway joints, flexible connections | terminology only; conductor sizing and installation acceptance require current source and AHJ review |

- Use this table for preliminary reference and arithmetic checks only.
- Confirm equipment ratings, product markings, installation conditions, utility requirements, and the local authority requirements before design or field use.
