A 15 or 20 amp receptacle must be located within how many feet of a rooftop air conditioner?

The requirement for a receptacle to be located within 25 feet of a rooftop air conditioner is grounded in the need for convenience and safety in maintaining and servicing the equipment. Frequently, HVAC systems require electrical connections for operation, and having a nearby receptacle minimizes the risk of running extension cords from far distances, which can pose safety hazards such as tripping or overloading circuits.

This proximity also facilitates easy access for service personnel to plug in diagnostic tools or equipment needed for repairs without the need for excessive maneuvering around the rooftop, which can be potentially dangerous. It is essential for the receptacle to be readily available to ensure the effective operation and maintenance of the HVAC system while adhering to electrical codes and standards.

The other distances presented in the options do not align with the commonly accepted requirements, either exceeding what is necessary for safe access or failing to comply with the guidelines set forth in electrical codes. Hence, the standard of 25 feet emerges as the most practical and widely accepted answer.
