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.

Reference basis summarizes public electrical safety and manufacturer education terminology; current standards and local authority review govern field use.
TermPlain-language useCommon contextBoundary
GroundingConnecting a system or equipment point to earth for voltage reference and fault or surge contextgrounding electrode, system grounding, surge referenceterminology only; conductor sizing and installation acceptance require current source and AHJ review
BondingConnecting conductive parts together so they remain at the same electrical potentialequipment bonding, raceway bonding, metal partsterminology only; conductor sizing and installation acceptance require current source and AHJ review
Equipment bonding conductorConductive path intended to connect non-current-carrying metal parts together and back to the source pathequipment frames, raceways, enclosuresterminology only; conductor sizing and installation acceptance require current source and AHJ review
Grounding electrodeConductive object or system in contact with earth as part of the grounding systemground rods, plates, concrete-encased electrodesterminology only; conductor sizing and installation acceptance require current source and AHJ review
