Is it legal to fasten 24v HVAC DDC cabling directly to the air supply duct work(on the outside of duct) it controls? If you have a network of DDC system controllers comprised of several VAV devices along a section of supply duct work, is it permissible to attach the cabling (24Vac) to the duct work with approved cable supports?
