Flexible cords for kitchen range hoods must adhere to which of the following length specifications?

Flexible cords used for kitchen range hoods must comply with specific length requirements to ensure safe and effective operation. The requirement for a minimum length of 18 inches and a maximum length of 36 inches strikes a balance between providing enough flexibility for the appliance's installation and operation while preventing excessive slack that could pose a tripping hazard or get caught in moving parts.

The rationale for this specific range allows for proper placement of the range hood above the cooking surface, facilitating ease of use and access. At the same time, adhering to these length specifications ensures that the cord can tolerate the heat levels and potential wear and tear associated with kitchen environments. This promotes safety by reducing the risk of mechanical damage to the cord and maintaining the integrity of the electrical connection.

The other options do not meet the established safety standards, which are informed by industry codes and regulations guiding electrical installations and appliance usages in residential environments. Thus, the correct choice reflects adherence to these necessary safety measures while ensuring the range hood operates efficiently and safely.
