Static grounding systems like the Earth-Rite range combine interlock control and visual indication to verified
ground connection points and offer the highest levels of protection over electrostatic ignition risks. However, equipment specifiers may select passive grounding devices, like single pole clamps, to ground and bond plant equipment.
Clamp Pressure Testing ensures the grounding clamp is capable of establishing and maintaining
low resistance electrical contact with equipment (FM approvals)
Electrical Continuity Testing ensures the electrical continuity from the teeth throughout the grounding
clamp is less than 1 ohm (FM approvals).
High Frequency Vibration Testing ensures the grounding clamp is capable of maintaining positive contact
when attached to vibrating equipment (FM approvals).
Mechanical Pull Testing ensures the grounding clamp cannot be pulled off the equipment without an intentional application of force (FM approvals).
Sources of mechanical sparking ensures no mechanical sparking sources are present in the clamp (ATEX certification).
