Journeyman Electrician Practice Exam

What is the maximum voltage allowed for low-voltage electrical equipment in health care facilities that is not approved as intrinsically safe, double-insulated, or moisture-resistant?

1. 10 volts

2. 20 volts

3. 30 volts

4. 50 volts

The correct answer is: 10 volts

In health care facilities, there are stringent safety standards in place to protect patients and staff from electrical hazards. Low-voltage electrical equipment must adhere to specific voltage limits to ensure safety when the equipment is not approved as intrinsically safe, double-insulated, or moisture-resistant. The maximum voltage allowed for such low-voltage electrical equipment is typically set at 30 volts. This voltage limit is established to minimize the risk of electric shock and other hazards in a sensitive environment like a health care facility. Equipment operating below 30 volts is generally considered safer, reducing the likelihood of severe injuries in case of a fault or accidental contact. Thus, in this context, the limit is set to 30 volts, ensuring that even in the event of a malfunction, the risk of harm is minimized to both patients and caregivers. This standard is vital for maintaining safety in environments where individuals may be vulnerable. Based on this information, the answer indicating 30 volts as the correct maximum voltage aligns with established safety protocols for health care settings.
