I have a project going on where I need to install a 120V control panel in an outdoor switchyard with 6.9kV enclosed bus duct run overhead (approximately 15' above grade). It has been suggested to mount the panel to a steel column supporting the bus duct, as it is close to the cable trenching already installed in the switchyard. Note the reason for the suggestion is that there is oil sample piping also connected to the control panel that we don't wish to bury -- we would instead install it in the cable trench for a degree of additional protection.
I can make the installation meet the requirements of 110.26(A), and I don't see anything in 110.26(E)(2) that gives me heartburn, but the scenario is something that just doesn't "feel" like the right thing to do. Has anyone performed an installation similar to this in the past, or is there a code section I'm missing that would change things? My preference is to mount the control panel in a different location on a concrete pad where it isn't under any bus duct, and bury the oil piping, but I can't find any code driven reason to do so. Any input is appreciated.
