solid copper rod of at least 1/2-inch diameter driven to a depth of at least 8 feet into the earth below the permanent
moisture level.
Work Clamp
1. Attach the work clamp to the workpiece or to the work table. Make sure that the work clamp and the workpiece
or work table make good metal-to-metal contact.
2. Do not attach the work clamp to the portion of the workpiece being cut away (see Figure 3-8).
3. For more information, refer to the National Electrical Code, Article 250, Section H, Grounding Electrode System
