Ontario Code Experts, Garage panel?

[Nick_Wa]

So I have my wiring complete in the garage (save for adding exterior lights and the interior lights). I still need to run main feed from house panel but want to check my panel is installed and setup correct right now.

I removed the copper clip that attached the neutral bar to the back of the panel. I assume this is what I needed to do so the neutral and ground weren't bonded.

I will be coming in with 3 gauge wire (3 conductor + ground) to feed 100 amps to the garage with 1.5" conduit coming in and up to box.

I also heard (and it doesn't appear to say specifically in my Ontario Code Simplified book) that we don't ground the box in the garage with ground rods but instead just have the ground being fed from the house panel which is grounded with rods as the main service entry? Any thoughts/clarification on this?

Thanks

If the garage is detached, here in the US ground electrodes are required at the detached structure. The ground wire that runs back to the service is the equipment ground conductor and is entirely different than the electrode conductor for the earth grounding system. I would think CEC is the same.

Edit: But I forget that Ontario isn't part of Canada.

I would assume so too but have heard/read differently for Canada. I just want to find out for sure.

In my current research, I'm discovering the same thing. However, in my previous garage, I was advised to install a ground plate, which I did.

Apparently it is a "ground loop" issue in the case that both grounding locations are not at the same potential. When there is only 1 ground with ground wire travelling from detached garage back to the main panel to the ground there, there is only 1 ground.

Makes sense to me but I am certainly not an electrician ha.

That would be the Quebec miniorty. . . They don't believe they are part of Canada!

They can get the **** out anytime, nobody will miss them.

Ooops, that's correct. I was thinking Ontario. I have been to Montreal a couple of times and have found the people not too friendly to us Americans.

Well, don't feel too bad. They (the minority of them, not all) don't like the rest of Canada!

You're not missing too much . . .

I live in Ontario, Canada, and we just had the electrical hooked up to my workshop. Power was supplied from the house, but was grounded with a ground plate by the workshop.
