发明名称 Electrical grounding device for wells
摘要 An assembly for securing a pump ground wire to the interior of a well casing comprises a support member adapted for placement into the well casing at its upper end. The support member is suspended within the well casing by a pair of suspension members having lateral tabs for resting on top of the well casing. A ground connection system is provided for establishing a ground connection between the pump ground wire and the well casing without connection to the exterior of the casing and without forming an opening in the well casing. Various embodiments are illustrated for establishing the ground connection between the ground wire and the well casing, utilizing the support member for achieving the ground connection.
