Final answer:
The best description for the sorts of things covered by electrical equipment ratings is limits on voltage, current, and temperature (Option D).
Step-by-step explanation:
Electrical appliances are commonly rated in terms of amperes for the current they need, in watts which is a measure of power, and they are subject to safety features such as circuit breakers, which are rated for a maximum current to protect against thermal hazards. These ratings ensure that the appliance can operate safely and effectively without the danger of overheating or causing electrical problems.
Voltage ratings are important because they indicate the electrical potential difference the appliance is designed for, while current ratings provide information on the flow of electricity the device can handle. Temperature ratings are important for the safety and longevity of the device. It is crucial to adhere to these ratings to prevent accidents and maintain efficiency.
Thus, the correct option is D.
