What is the maximum distance a receptacle outlet for servicing HVAC equipment should be located?

15 feet
20 feet
25 feet
30 feet

The correct answer is: 25 feet

The National Electrical Code (NEC) specifies that receptacle outlets used for servicing HVAC equipment should be located no more than 25 feet from the equipment. This requirement is intended to facilitate safe and convenient access for maintenance and servicing tasks, ensuring that technicians have easy access to power without needing to use extension cords, which can present safety hazards. By placing the receptacle within 25 feet, it minimizes the distance technicians must travel while servicing equipment, thus reducing the risk of accidents and improving efficiency. This distance also takes into account the typical reach of standard power cords for tools and diagnostic equipment that technicians may use, promoting safety and effectiveness in servicing systems. This guideline is a key aspect of ensuring the safe and efficient maintenance of HVAC systems, which is crucial for their proper operation and longevity.
