Bull, MV switchgear always need to be grounded, and thier grounding clusters need to be tested and rated for the available fault current on the system they are grounding. You dont just go out and "Get trained up" on MV gear. Many companies require all work done on MV (And some LV stuff like switchgear and transformers) to be done only by a "Certified" company and "Certified" technition or testing engineer. Certified is through NETA or NICET.

Are far as the elbows, any real power system testing company will have the grounding elbows for this type of installation. Another good solution is to install the ball studs for grounding ( AB Chance or salisbury have these). There may be a better solution if I knew mor about the equipment.

In the meantime you can find a Certified" testing company in your area at www.netaworld.org
