Is it true that if an evaporative cooler is mounted on the roof of a dwelling, a service receptacle is required to be located within 20 feet?

The statement regarding the requirement for a service receptacle near an evaporative cooler mounted on a roof is false. Generally, there are specific guidelines and codes that dictate when and where service receptacles must be installed in relation to equipment such as evaporative coolers. If the unit is installed in a location that is not easily accessible, such as on a roof, a service receptacle may not need to be located within a specific distance for safety or practical reasons.

Typically, service receptacles are required to be in convenient locations to provide easy access for maintenance and servicing of HVAC equipment. However, for equipment installed on roofs, the requirements might differ. Factors such as the type of building, accessibility, and local codes can influence whether such a receptacle is necessary. In this case, the notion that it must be within 20 feet of a roof-mounted cooler is not a blanket rule, which confirms that the correct answer is that the statement is false.
