Air-conditioning equipment must have a means for interrupting electrical supply within how many feet?

  1. 50 feet

  2. 35 feet

  3. 25 feet

  4. 15 feet

The correct answer is: 15 feet

The requirement for air-conditioning equipment to have a means for interrupting electrical supply within a specific distance is established to ensure safety and accessibility. The correct choice indicates that the means of disconnection should be located no more than 15 feet from the air-conditioning equipment. This proximity allows for easy and quick access in case of emergencies or maintenance, minimizing risk and ensuring that personnel can safely shut off power when necessary. Having a disconnecting means close to the equipment is vital during servicing, as technicians often work in potentially hazardous areas. If a technician needs to power down the system quickly to address a malfunction or emergency, the disconnection should be easily accessible without requiring them to travel a far distance, which could pose additional risks. This standard is designed to protect both the equipment and the technicians working on it, allowing for a safer working environment. Generally, other options might suggest longer distances, which would not provide the same level of immediacy and accessibility crucial for safety procedures in HVAC work.
