Guys I have to point out that the plural in "feeder(s) between the main disconnect and the lighting and appliance branch-circuit panelboard(s)" is meant to apply to multiple dwellings that are supplied with single phase 120/240 service.

Tom, you may be right, maybe you do have inside info on this, maybe your contact is 100% correct.

Here is the problem, all electricians are supposed to be able to use and apply the code without 'inside info'.

Right now there is no language in the code article to support (or dispute) your stated reasons for the (s).

As they do not tell us what the (s) is for, we can use it as we like. [Linked Image]

And I agree, this table does not apply to parallel conductors.
