I take it that table 16 and 17 have changed in Sask since the 2002 code.
We haven't adopted the 2006 but the inspection department has been allowing us to use either. In 2006, Table 18 is gone and table 17 is changed.
If you calculate the size of neutral for every house, I would expect that, in most cases, the neutral would be reduced and in many cases by more than two trade sizes. I've reduced the neutral by two sizes for so many years that I can't imagine not reducing the neutral. Reducing by more than two sizes seems odd, but it must be okay or it wouldn't be in the code.
