Which of the following is NOT a contributing factor for a person receiving an electric shock?

Properly sized overcurrent protection in the circuit does not contribute to a person receiving an electric shock because its primary function is to prevent excessive current from flowing through the circuit, thereby helping to avoid situations that could lead to electric shock or fire hazards. Overcurrent protection devices, such as circuit breakers or fuses, are designed to interrupt the flow of electricity when the current exceeds a certain level, effectively minimizing the risk of dangerous electrical conditions.

In contrast, the other factors listed directly influence the likelihood and severity of an electric shock occurrence. The path of current through the body determines how the electrical current travels, affecting the potential harm to the individual. The condition of the grounding system is critical for ensuring that stray or fault currents are safely directed away, reducing shock risks. Voltage levels at the contact point indicate how much potential electrical energy is available, which also correlates to the potential for causing an electric shock. If these other factors are not properly managed, they can increase the risk of receiving an electrical shock.
