Default Ontario Meter bonding

So with the new code, doing a Resi service upgrade, do we have to pull a bond back to the meter base?

I ground my neutral in the panel and then run a bond back out to the meter through the PVC?

No.

Ontario has a bulletin that says do it the old way for now.

The new way can not be done with the meter bases we have now so until the manufacturers change their meter bases, we can do it the old way

You get access to them when you buy the Ontario code book

Why can't your suppliers get the new meter bases? They sold an insulated neutral kit here for awhile, and now the meters come with it pre-installed. At least the 100A and 200A do.

Isolated neutral kits have always been available here. What is not available yet is a single service meter base with extra lugs on the neutral for bonding and grounding.
The screw that currently connects the neutral bar to the base is not rated as a bond, and there is no extra lug on the neutral bar for grounding at the meter base so you can only do one of the two options now given in the 2018 Code for grounding the service.

Just did a service upgrade 200 amps in toronto. Installed Neutral isolated kit at meter base and #6 bonding conductor back to combination panel in service raceway, where neutral is bonded to ground. Passed inspection.

Ground everything, I always do the panel with the service ground because I can get at it again without a utility crew, their fees and a permit.. Makes it easier to touch it up if there's corrosion or a addition and a new plate/ grounding configuration.

I like it in the panel because that is the manufacturers spot. Accessory crap like bonding bushings you just toss a #6 piece to it and thump a #2 lug in with a tapping screw, I don't even scratch the paint off anymore. If it's a main ground I will remove paint.

Out in BC though, I probably need an update on amendments... f*****n things. Funny though when you've been doing better than code for a long time and code starts catching up to you! Then it's coming up with more demanding rules and you think "that's a new stupid waste of time" 😄

We used to ground in the panel right on the neutral.. No goofy ass brass screw.. Nice big lug! But now that's wrong, bah! (Actually never liked that one)
