Question 6A114

For the protection of personnel handling a transmitter, it is crucial to **ground all exposed metal parts**. This establishes a safe path to earth for any stray current in the event of an electrical fault or insulation breakdown. If an internal component fails and energizes the chassis, grounding ensures the dangerous voltage is diverted away from a person touching the transmitter, preventing electric shock. It also allows circuit breakers or fuses to trip, de-energizing the equipment. Option B is incorrect because "shunt grounded faults" is not a standard or primary safety measure for personnel protection. While equipment may have various fault protection systems, direct grounding of exposed metal is fundamental. Option C, discontinuing high-power operation, reduces the *potential severity* of a shock but does not eliminate the *hazard* of an energized chassis; a fault can still be dangerous at lower power. Therefore, D is also incorrect.
