We get lots of calls about why the Leister Triac-S gun only has two legs and no ground on its power cord.
“Hand held tools manufactured with non-metallic cases are called double-insulated. If approved, they do not require grounding under the National Electrical Code. Although this design method reduces the risk of grounding deficiencies, a shock hazard can still exist.”
This is good information for your safety meeting planning and you might want to print a copy to keep with your Double Insulated Leister Triac-S.
