When you plug a device into the wall in the United States, you are using a specific type of electrical connector that has defined standards for safety and functionality. These fixtures are technically known as electrical receptacles, but they have several common names that vary by region and context. Understanding what these components are called and how they work is essential for anyone involved in construction, electronics, or general home maintenance.
Common Terminology for Wall Outlets
In everyday conversation, the most likely answer to "what are American outlets called" is simply "outlets." However, you will also hear them referred to as wall outlets, receptacles, or sockets. Electricians often use the term "duplex receptacle" to specify the standard two-pronged variety, distinguishing it from other configurations. These terms are largely interchangeable, though "outlet" remains the most universally understood vernacular in the United States.
The Historical Origin: The Edison Plug
To truly understand what American outlets are called, one must look at their origin. The design is based on the work of Thomas Edison and his team, who developed the original polarized plug and receptacle system. Because of this foundational work, you will sometimes hear older generations or experienced tradesmen refer to them as "Edison plugs" or "Edison receptacles." This term specifically denotes the two-prong layout that served as the blueprint for the modern three-prong safety standard.

Modern Standards and Safety Features
While the physical appearance dictates that they are called outlets, the modern versions are defined by strict national codes. The National Electrical Code (NEC) mandates specific configurations to protect users from electrical shock. The standard version is called a 15-amp or 20-amp receptacle, named for the amount of current it can safely handle. You will find these outlets painted in a standard cream color, though decorative covers and plates are common to match interior design schemes.
Identifying the Configuration
The specific type is usually determined by the number of vertical slots on the face of the device. A standard configuration features two vertical slots side-by-side and a semi-circular ground hole, which defines it as a Type A or Type B receptacle. Travelers to the US will quickly learn that these are the only types of outlets generally compatible with international electronics, provided the voltage is correct. If you are looking at the hardware itself, the terms "jitterbug" or "cheater" are informal slang for the two-prong variants that lack grounding.
Regional Variations and Nicknames
Although the engineering is standardized, the language used to describe them varies across the massive country. On the East Coast and in urban centers, the term "outlet" dominates. In the Midwest and Mountain West, you might hear them referred to as "wall taps." While this usually refers to a specific brand or hardwired junction box, it highlights the linguistic differences in what Americans call these fixtures. Regardless of the nickname, the function remains the same: to deliver safe power to appliances.

Distinguishing from Similar Fixtures
It is important to differentiate these standard fixtures from other devices that might be mounted on the wall. You should not confuse a standard electrical outlet with a USB charging port, which is a relatively modern addition to the landscape. Furthermore, they are distinct from telephone jacks or cable TV coaxial outlets, although they often sit adjacent to one another in a wall plate. If the fixture delivers general-purpose electricity to charge a laptop or lamp, it is universally called an outlet in American English.
Global Context and International Comparisons
Because "what are American outlets called" is a frequent question from foreigners, it is useful to compare them to other standards. Unlike the Schuko plugs found in Europe or the Type G plugs used in the UK, the American standard is uniquely polarized, meaning one slot is wider than the other. This physical distinction ensures the plug can only be inserted one way, enhancing safety. Therefore, while the device might look different to an international visitor, its core identity as an electrical outlet remains constant.
Conclusion on Terminology
Whether you are a DIY enthusiast, a traveler, or a new homeowner, knowing the vocabulary helps ensure clear communication. The simple answer to the question is that they are called outlets, specifically the duplex receptacle type based on the Edison design. While slang terms like "wall tap" exist, referring to them by the standard industry name ensures that instructions regarding installation, repair, or replacement are understood correctly by professionals across the country.
