What distinguishes an appliance from other equipment?

An appliance is specifically designed to perform a particular function, often as a standalone unit that is installed to carry out that function effectively. This characteristic sets appliances apart from other types of equipment, which may be more general-purpose or serve multiple functions. For example, a refrigerator is an appliance because it is specifically designed to cool and preserve food, whereas a general piece of equipment might include tools or devices that can serve various roles based on user requirements.

The clarity in function and typical installation defines appliances in the context of electrical systems. This distinction helps to categorize devices in compliance with safety codes and standards, ensuring that they are used correctly and efficiently within their intended applications.
