I was searching for info on this topic and found an old thread here. Several people stated that there was no applicable code. Article 300.11(b) states that conduit can be used to support other conduit and devices under three conditions. 1) Where the raceway or means of support is identified for the purpose. (very limited use) 2) Where the raceway contains power supply conductors for electrically controlled equipment and is used to support Class 2 circuit conductors or cables that are solely for the purpose of connection to the equipment control circuits. (Doesn't apply in majority of situations) 3) Where the raceway is used to support boxes or conduit bodies in accordance with 314.23 or to support luminaires in accordance with 410.36(E). (very limited usage)
In Short: except for these very limited exceptions, the answer is NO.
I don't see why anyone would think this isn't applicable. Also, why would anyone want to support their work from someone else's work? Where does that end, when the system collapses?
