We installed some make up air units and the electrician ran the power wiring through the duct work up to the motor. I have seen this from time to time but never had it done on equipment I will be servicing. Or done so poorly. The MC is just floating around inside the duct work with no support. When they went through the fan deck they looped the wiring and it is also just floating around. The jack ass used wire ties to hold it and they have pulled loose even before the units have been started. When it was seen what they were planning on doing they were told it was unacceptable and they said they would change to the roof penetrations we provided. After we left they did it anyway. When approached about it the electrician said it's code so screw you. We know from past experience that there will be problems ... like noise, like vibration, like the MC being cut into.
So, does anyone know the code on this?
Have you had this problem, if so how did it get resolved (if it did)?
