Deep Dive: G0B11
The correct answer is D: They must be bonded together with all other grounds. What is required for lightning protection ground rods is that they must be bonded together with all other grounds. All grounds (lightning, electrical, equipment) must be bonded together to prevent potential differences. For amateur radio operators, this is critical electrical safety. Understanding this helps ensure proper grounding.
Why Other Answers Are Wrong
Option A: Incorrect. Ground rods don't have to be bonded to all buried water and gas lines - they must be bonded to other grounds, not necessarily water/gas lines. Water/gas lines aren't the requirement. Option B: Incorrect. Bends in ground wires don't have to be right angles - bends can be gradual. Right angles aren't required. Option C: Incorrect. Lightning grounds don't have to be connected to all ungrounded wiring - they must be bonded to other grounds. Ungrounded wiring isn't the requirement.
Exam Tip
Lightning protection ground rods = must be bonded together with all other grounds. Think 'L'ightning 'G'rounds = 'L'inked 'G'rounds (bonded). All grounds (lightning, electrical, equipment) must be bonded together to prevent potential differences. Not water/gas lines, not right angles, not ungrounded wiring - just bonded to all other grounds.
Memory Aid
Lightning protection ground rods = must be bonded together with all other grounds. Think 'L'ightning 'G'rounds = 'L'inked 'G'rounds. All grounds (lightning, electrical, equipment) must be bonded together to prevent potential differences. Critical electrical safety requirement.
Real-World Example
Lightning protection ground rods: They must be bonded together with all other grounds (electrical service ground, equipment grounds, etc.). This creates a single ground system, preventing potential differences that could cause problems. All grounds must be bonded - this is the requirement. This ensures proper grounding and prevents dangerous potential differences.
