Final answer:

Electrical equipment ratings typically refer to the required amperes (amps) for operation and the wattage, which measures energy consumption per unit time. Energy consumption is also represented in kilowatt-hours, considering the duration of power use. Safety devices like circuit breakers and GFCIs are rated based on the maximum current they can handle to prevent hazards.

Step-by-step explanation:

The ratings that you see on electrical equipment, such as appliances, fuses, and circuit breakers, typically refer to amperes (amps) and watts. The wattage rating of an appliance indicates the rate at which it consumes energy and does not depend on how long the appliance is on. A device that is off is considered a zero-watt device, as it is not consuming power at that time. However, energy consumption is often measured in kilowatt-hours (kWh) because this unit takes into account the time over which power is consumed. For example, a 100-watt light bulb running for 10 hours would consume 1 kWh of energy. Other safety systems, like circuit breakers and GFCIs, are designed to interrupt excessive current to prevent hazards and are rated for a maximum current at which they will trip.

When considering the overall safety and functioning of an electrical system, it's important to recognize that devices like circuit breakers and GFCIs are designed to react fast to prevent damage and potential injury from faults in the electrical system.

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.
