Thats what I thought as well. The inspector here said #6 was fine as well for the water pipe as well as the secondary ground that's required.

I'm doing this one myself. The inspector here has been really helpful with all the prep work. In BC, homeowners can pull the permit for service upgrade work. The poco won't hook it up until the inspector ok's it anyway. I've gotten a ton of info from here that made me feel this job is quite doable on my own.
I get to start digging the trench tomorrow for the buried conduit since I'm moving the meter location. I can't wait for all that digging!

Speaking of trenching, I can't seem to find anywhere what the requirements are for underground service conduit in regards to drainage? The only thing the poco info says is that it must be "drained at the building entrance as per the CEC". Can anyone tell me what the requirement is? I'm using DBII pvc 3" conduit.

I want to make a point here. This post is concerning Canadian Electrical Code, not National Electrical Code (US).

the neutral allowed in Canada is not legal in the US

I think it is a poor allowance but they allow it. While they are correct that the neutral carries the unbalanced load, depending on how a house is wired and how the power is used, that 65 amp rating of that wire can be surpassed without too much difficulty. I see it as cheap insurance to be sure it isn't.




btw guys, that is why I posted:

at least in the US.

a couple posts back but thanks for posting the CEC requirement rovers.

It's great to learn about the differences from Can/US codes. I like the debate back and forth. I've decided I will definitely go bigger than the minimum on my neutral, since its such a short run anyway.
But does anyone know about the CEC regarding the drainage for the conduit? I still can't find it anywhere. Thanks guys.

As a former Canadian, I will definitely try to obtain an updated copy of the Canadian Electrical Code. I kept a copy of the code for many years after I emigrated from (Yes. Leaving a country is spelled with an "E". Coming into a country is spelled with "I".) Canada! But that doesn't help you very much at this time. I'm certain, there's a link to active CEC. One of the DIY'rs/Electricians from Canada should be able to help you. Good Luck.!

Thanks for the info everyone. I'm only really concerned with how this applies to the CEC (although it is cool to learn about the differences with the NEC).
This particular installation is an underground service.

I beleive they drill a hole in the bottom of the LB, and i beleive they also pack it full of duct seal as well.

I don't do residential so i have never done a residential service before, something simple like this i would ask the inspector what he wants to see.

Don't forget the plasting bushings in the meter, and a grounding bushing in the panel. This only applies if you are useing EMT, if your useing PVC it still doesn't hurt to use the bushings in the meter but are not neccasry.

Thanks Darren,
I was planning on having the pvc come up from the ground to the bottom of the meter base, and the feeder wires going through the back to the panel inside? Am I wrong in thinking I won't have and LB?? Or am I just confused here.

I am using emt between the meter and panel, and I have the locknuts and the ground bushing already. By plastic bushing, do you just mean the push in type that go inside the emt fitting to stop the wire rubbing? The ground bushing itself has a plastic sleeve inside already.

Like i said i don't do residential so i am not sure hows it done. So i'm guessing your panel is on the ground floor and not in the basement.

Here is what i mean by plastic bushing.

Yes, the house is on a slab on grade and the panel is on the ground floor. The meter and panel are basically back to back. Thanks for the pic of the bushing, I see what you mean now. I'll make sure to pick a couple up.
