Questions and answers
What equipment uses a chassis ground?
A chassis ground is used in all electrical (electronic) equipment, vehicles, and generators. (paragraph 1-8)
How should clamp or screw connections be secured?
Clamp or screw connections tightly to prevent loosening over time. (paragraph 2-6)
How much surface contact must grounding plates have?
The plates must have at least three square feet of surface contact with ground (front and back of plate is 18 inches by 18 inches). (paragraph 2-21)
How far below the terrain should a ground rod be installed?
Ground rods should be Installed to full length so that top of ground rod is 3-5 inches below terrain. (paragraph 5-14)
When can chemicals be added to lower ground resistance?
If your ground resistance, as measured by a null-balance earth tester or equivalent device, is 25 ohms or more, you may add chemicals to lower the resistance. (paragraph 3-5)
