General exam question G4C09

How can the effects of ground loops be minimized?
- A.Connect all ground conductors in series
- B.Connect the AC neutral conductor to the ground wire
- C.Avoid using lock washers and star washers when making ground connections
- D.Bond equipment enclosures together (correct answer)
WhyThe effects of ground loops can be minimized by bonding equipment enclosures together. Bonding all station equipment enclosures together keeps them at the same RF potential, which removes the voltage differences between chassis that drive current around in unwanted ground loops, answer D. Connecting grounds in series (rather than to a common point), tying AC neutral to the ground wire, and avoiding star washers don't address the underlying cause of a ground loop and some of these would create other hazards.
