What should be done to all external ground rods or earth connections?

• A. Leave them separate to avoid potential differences
• B. Bond them together with heavy wire or conductive strap
• C. Use plastic connectors to insulate connections
• D. Install them at different depths for effectiveness

Answer: (B)

Bonding all external ground rods or earth connections together with heavy wire or a conductive strap is essential for creating a common ground reference point. This practice minimizes the risk of potential differences between various ground points, which can lead to safety hazards and equipment malfunction. When grounds are bonded, they equalize the electrical potential, reducing the chance of shock hazards and ensuring better performance of the equipment connected to these ground systems. Additionally, having a unified ground system helps divert lightning strikes and other surges effectively, directing them safely into the ground without creating dangerous voltage differentials between different grounding points. It enhances the overall safety and reliability of the electrical system in the installation, especially in a radio station or similar setups where equipment might be sensitive to variations in ground potential. In contrast, leaving ground rods separate may lead to significant potential differences, creating unsafe conditions. Using plastic connectors would isolate the ground connections, which is counterproductive, and installing them at different depths does not effectively address the need for a common grounding system.
