Can someone tell me if there is a rule in the CEC that mentions the partition between the main breaker compartment and the rest of the breakers in a panel board
Thanks
Doug

The only rule I could quickly find that states this (somewhat) is 6-306(a):
"Consumer's service raceways shall
(a) contain only the consumer's service conductors..."

If it's for service equipment it must be marked "approved for service entrance", so a barrier will come with that approval.

Thanks that what i found too.

Rules 6-306 & 6-212 make mention of it in a round abouts way.

This was my original question to Doug via a private message. I have heard that the panels used in Canada are designed with a cover arrangement that permits access to the load side breakers and bus without exposing you to the line side terminals on service equipment. If this is true I think that it is a great safety idea and would like to start the process of making such a requirement in the NEC. I guess I have two questions. Is your service equipment designed as I stated above? If so what code or standard requires this?

Doug, thanks for helping out with this question.

Some panels. I can't speak for all have a two part panel cover. One part covers the main and the second part covers the breakers.

Doug, do you have a copy of Part 2 of the CEC? Could be some additional rules in there that can help you out.

No I dont have part2 have part one and the CD for the cost of the CD they should put part 2 on it too.:(

This is where I assume we find it in Part 2
