Connectors & Grounding — Blackburn® Grounding Systems Overview Blackburn® EZGround™ Compression Connectors represent a low cost, code-approved alternative to welded ground grid connections. EZGround™ Connectors can be safely installed in half the time, with fewer components, and in all weather conditions. The range-taking capability of each EZGround™ series connector translates to fewer parts needed to complete the ground grid.
Overview The EZGround System Thomas & Betts offers its complete line of grid-ground compression connectors. Our EZGround™ connectors are designed for direct burial and offer a safe, efficient alternative to exothermic welding products. Grid-ground installations do not require explosive charges and can be installed in various climate conditions. These range-taking products will reduce the number of connectors and dies needed for your installation.
