How is grounding of 10250T and HT800 devices accomplished?

Both pushbutton product lines meet UL/CSA grounding requirements based on a solid wire connection or the use of metal cutting nibs. The advantage of the HT800 grounding kit (HT8GR1 or GR2) is that it enables grounding of the HT800 pushbutton operators/lights when installed in both metal and plastic enclosures and panels. The 10250T grounding nibs provide operator grounding when mounted in metal enclosures/panels only whose surface coating is not excessive and the required torque is applied to penetrate the coating. However, a grounding kit (10250TKG1) is available for providing a separate grounding circuit when 10250T operators are mounted into plastic enclosures or metal panels with heavy surface coating.
