The grounding system includes conductors and ground rods around the building. Here is Craig preparing to connect the conductor to a rod. |
The conductors and ground rods are connected by a Cadweld connection. This is done by using a graphite mold and a filler material made with magnesium and other metals. |
 |
 |
The mixture is then ignited with a striker through the side of the mold. |
The moment of ignition! This process generates temperatures of more than 2000 degrees. |
 |
 |
A look into the mold a minute or so past ingintion. The weld is still red hot. |
The resulting connection. This will never corrode or loosen over time as clamps can do. |
