    Only some designs of drains let all of the water out of the enclosure. Other designs leave an 1/8" of more of water in the bottom of the enclosure.

    Neither the main rule nor that exception are needed in the code. The combination puts us right back where we were before there was a rule that said you can't use the EGC as a GEC. With the...

    What type of jacket does the multi-conductor cable have? If the cable has a magnetic jacket, then all of the circuit conductors and the EGC have to be within that jacket, and if the cables are in...

    It is my opinion that 725.136(I) permits the installation without any type of barrier. Since there is no specific subsection that covers the two systems within a raceway, it appears to me that "(I)...

    Note that the pulling tension calculator does not have an input for the radius of the bend for calculating the tension or pulling force. The radius is only used for the sidewall pressure calculation.

    I guess I need to retract my statement based on 300.3(B)(3). That would clearly apply to the NM and may apply to the cable in the cable tray based on that cable having a nonmagnetic jacket.

    It is my opinion that you can only do that where you are installing single conductors in the cable tray. If you are installing a multi-conductor cable, you need an EGC in each cable.

    It would be my opinion that neither one is code compliant. If you have a cable assembly the EGC must be part of that cable assembly. It cannot be run external.

    So based on that reasoning, you must also require a bonding jumper at each and ever joint in the water piping system. Pipe joints are not designed or tested as a fault clearing path.
