All of the following information is required to be on an electric comfort appliance cable EXCEPT?

In the context of labeling requirements for electric comfort appliance cables, certain information is mandated to ensure safety and compliance with industry standards. The manufacturer's name, voltage rating, and power requirements are all essential elements that must be present on the cable. These specifications help users understand who produced the appliance, the safe operating voltage, and the necessary power specifications, which are crucial for proper and safe usage.

The manufacturer's date code, while useful, is not a requirement on the cable itself. This information may help in tracking production batches and warranty claims but does not directly pertain to the operational safety or specifications of the electrical appliance. Thus, the absence of the manufacturer's date code on the cable does not violate safety regulations, making it the correct choice as the piece of information that is not required.
