I'm use to Canadian main distribution panel (residential) and they are different to the US ones in the following manner:
The Canadian ones have a "Ground" bus the only thng that you can connect to this one is the ground wire or bare or green insulated wire. It is connected to the panel box and the grounding rod.
It also has one or two (depending on brand) neutral bus. The neutral bus has a solid bar connecting it to the neutral wire of the service.
Of course, using a ohm meter, the neutral and ground bus are at the same potential or I should say will show continuity on an ohm meter connected between ground and neutral.
Where as in the US both the ground and neutral (bare and white insulated wire) are connected to the same bus.
Question:
What is the difference?
Does the grounding/bounding operate in a different way?
Why the difference?
Thanks
