Default Split bolts to extend ground

Is it correct that a split bolt can be used to extend a ground now and we no longer require compression type fittings?

I wish the NEC would follow suit.

The irreversible splice thing for GEC's is sooooooo stupid. If you make a splice in the GEC in a place where no one will ever see it or have access to it, it's needs to be irreversible. But that same GEC connects to an exposed ground clamp with a screw lug. And the conductor itself can be cut with a pair of homeowner pliers.

Sounds to me like a complete proposal you have there. Complaint and substantiation. Send it in.............

Interesting.. I have a high press so I'm covered but is that a provincial change or is it Canada wide in the CEC?

Canada wide.

The old code [10-806(1)] that stated "without splice except if you use a compression tool etc, etc" is gone.
The new code just says it must be electrically continuous (10-116)

Except in BC the 2018 doesn't come into effect until January 1, 2020.

K, so it’s Canada wide code, not including BC and Quebec.

not allowed here in MB

Both Hydro and City of Winnipeg

Rule 10-116 (1)and(6) 21 Subrules (1) and (5) of Rule 10-116 (Installation of grounding conductors) are replaced with the following:

(1) The grounding conductor for a system shall be without joint or splice throughout its length, except in the case of busbars, thermit-welded joints, compression connectors applied with a compression tool compatible with the particular connector

For me a #6 split bolt is more expensive then a #6 butt crimp, so I will stick with the crimp... Plus for what ever reason I just think it is better connection, but I don't have any proof of that.

Cheers

That is surprising. The grounding conductor has been reduced in size over the past few code cycles and new grounding rules for transformers have been brought in like allowing the primary bond to be used as the ground for the secondary. 10-212(2). Did they remove that code too?

One of the reasons they removed the compression tool requirement is for installations that have a ground bar. Technically that old code, that has been kept in the MB code, would not allow you to connect the grounding wire from a transformer to a ground bar unless you use a thermit weld or a compression tool which is not possible.

That might come under the "too old to change and it's better the old way" category. I use #6 ground cautiously, if I'm doing a meter/breaker or the ground is right outside the panel I stick with #2 or 3 bare just for mechanical resistance to weed eaters and homeowners.

#6, 1/2" PVC, heat gun for offset and I'm done.

Yes it is hard to convince the older guys to not run large oversized grounds as that was how they were taught. We used to have a table for ground sizes in the old books. Imagine trying to convince them they can now use the primary bond to a 75kVA transformer as ground for the secondary!

As for a #6 from a meter base, I always and would still run it in a 1/2” PVC for mechanical protection. Much cheaper than running an oversized wire.

I think there is a rule stating that #6 and smaller have to have mechanical protection.

I don't know if it is much cheaper especially on a pole ground.. It's only 3 or 4 meters of wire, probably $12 more, with the time and labour savings I think it's cheaper to use #3. I do both kinda depends what I got for ground wire plus if there's an upgrade later I'm not digging

What do you mean by not digging if there is an upgrade? #6 is good for the grounding conductor on all sizes of services.

Doesn't a 300A+ require the larger ground? I don't know too lazy to look this early.. It's also a good way to use up scraps.. Most of the time when I'm doing a pole there's no power around for a heat gun.. So I have to use my "flameless" torch.

No, #6 is all that is required.

10-114

1) Except as permitted by Subrule 2), the grounding conductor shall be sized not smaller than
a) No. 6 AWG if of copper; or
b) No. 4 AWG if of aluminum.
2) The grounding conductor shall be permitted to be sized smaller than prescribed in Subrule 1),
provided that it is not smaller than the current-carrying conductor(s) of the system being grounded.
