Grounding Plunger

The OPW Grounding Plunger replaces the use of external bonding straps/cables. The innovative spring-loaded, cable-free OPW Grounding Plunger ensures constant contact during production. The new design allows the swivel to rotate 360-degrees without pulling off the bonding straps or cables.

"Where the bonding/grounding systems is all metal, resistance in continuous ground paths typically is less than 10 ohms. Such systems include those having multiple components. Greater resistance usually indicates that the metal path is not continuous, usually because of loose connections or corrosion". NFPA77, 7.4.1.3.1
