circuit conductors in 2 separate multiconductor cables.

[worksooner]

Contractor is feeding a panel with 2 multiconductor cables. In the one cable they have the 3 phase conductors and the ground and in the second cable they are using 1 cable for the neutral or grounded conductor and not using any of the other cables. How I read 300.3(B) is that all circuit conductors have to be in the same cable. Has anyone ever installed cable this way? They are not parallel conductors.

Thanks.

Gibb's smack that contractor. Violation of the section you cited.

seems pretty clear given what you have told us that it is a violation.

It may be permitted if it complies with 300.3(B)(3)
