Gary Nuzzi, owner, Neptune Electric, Wall, N.J.; John Kelly, retired electrician, Leesburg, Fla.; and Paul Huddas, controls engineer, Atlas Technologies, Fenton, Mich., correctly identified the simple violation in this photo: The device used to make the connection was neither listed nor labeled for the purpose depicted. NEC 250.8, Connection of Grounding and Bonding Equipment, states “grounding conductors and bonding jumpers shall be connected by exothermic welding, listed pressure connectors, listed clamps, or other listed means. Connection devices or fittings that depend solely on solder shall not be used. Sheet metal screws shall not be used to connect grounding conductors to enclosures.”
