Happy Holidays group, In getting agency approval on our I.T.E. product, the safety ground terminal has come into question. When hard wiring a product, Para. 3.3.7 indicates that the conductor is to be clamped between metal surfaces, and the terminal shall not damage the conductor. This has been interpreted as the terminal must have a metal plate that clamps down on the conductor, and no rotational stresses from the screw are applied to the conductor.
In Europe, I understand that a rail terminal block, where one of the terminals is shorted to a rail, is generally used, and accepted, but somewhat costly. There may also be alternatives, but we haven't found an off the shelf one yet. I am looking for a grounding terminal that accepts #14-#18 AWG wire, has a clamping plate, is tin plated, and has a mount or hole for direct connection to a chassis. Since this has been so difficult a component to find, we had one designed. Now my question is, "How is everyone else dealing with this ground lug requirement? Is there a common component available that meets these specs? The ground lugs in common use in the electrical industry do not have the plate, and are copper or copper alloy.
