About this detail

A passenger boarding bridge base plate grounds to a concrete-encased electrode within the foundation rebar cage. A number 2/0 AWG bare copper grounding electrode conductor is exothermically bonded to the new foundation rebar cage and bolted to the base plate using a ground lug connection. All paint and protective coatings must be removed to allow a bare metal mechanical connection between the base plate and nuts, with touch-up paint applied after the final torque set. The concrete-encased electrode rebar requires a minimum length of 6 meters (20 feet), a minimum diameter of 13 millimeters (1/2 inch), and must be encased by at least 50 millimeters (2 inches) of concrete in direct contact with the earth.
