发明名称 Electrical grounding clamp
摘要 A removable electrical ground clamp is provided that is easily installed on an outside electrical meter or breaker box by establishing pressure contact with the box. An attachment lug is provided on the grounding clamp for connecting a ground wire for use when electrical power is to be brought to a residence or some other outside electrical work or installation. The grounding clamp is designed to eliminate the need for access into an area of a residence or other building to establish a ground connection, provides instant visual inspection; and two grasping arms can be moved along an elongated member, which can be cylindrical, hexagonal, or U-shaped, in order to securely grip the outer surface of the meter or breaker box.
