If 1 meg-ohm is adequate resistance to ground, then why do we test to 10 or 25 ohms?
Theoretically, a resistance to ground of 1,000,000 ohms is considered capable of dissipating a static electrical charge. So why then does my safety program (and NFPA 77) require a resistance to ground of 10 or 25 ohms OR LESS, depending on the metal used in my system? (e.g. end-to-end resistance of a bonding wire should…...
