Which Is The Correct Term? Receptacles, Electrical Outlets or Electrical Plugs?

We all have heard this electrical devices go by different names such as: receptacles, electrical outlets and electrical plugs. The truth is all the above terms have been adopted over time and are constantly interchanged but that does not necessary make it correct. Receptacle is the correct way to refer to the actual electrical device. This device is used on the daily basis. Electrical appliances are plugged into outlets to bring them to life. Such a simple device but makes the world of difference in comfort. Having the right amount of receptacles distributed throughout a home has never been more important in this day and age. Our Sharp Electric electricians can help bring comfort to your living space by adding electrical receptacles where you most need them.

Another type of general purpose receptacle found in the home is the single device electrical outlet.

One more detail I would like to share is of an easy way to differ a 15A rated electrical outlet from a 20A rated electrical receptacle. 20A plugs can be tell apart from 15A rated outlets by the side ways T on the left slot. Below is the comparison of the two:

Before we move on to a different style of receptacle I would like to cover basic details & frequently asked questions that will be useful  when becoming a homeowner. A common outlet question is can a 15 amp rated appliance be plugged into a 20 amp outlet? Absolutely, but a 20 amp rated appliance cannot be plugged into a 15 amp rated receptacle. If you need a refresher on why it isn’t possible please click here to learn the differences between a 15 amp & a 20 amp receptacle. Standard electrical outlets are not electronic devices. They do no have circuit boards inside of them that can fail and finally they are not serviceable as they come sealed from the manufacture and should be replaced at the first sign of wear. The only electronic receptacle/outlet that has existed for the longest is the Ground Fault Circuit Interrupter duplex receptacle or GFCI outlet for short  which we will discuss later. Modern duplex outlets are constructed of a front and rear hard plastic, brass internal contacts & side terminals and lastly everything is held together by a metal backbone.

How to choose the correct outlet when replacing them?

I have had a lot of homeowners ask me this and the answer is very simple. All electrical outlets have a (National Electrical Manufacturers Association) / NEMA identification number. This NEMA number differentiates all the outlets styles and ratings being manufactured.

This outlet & switch combo can be found in both newer and older homes. When utilized on newer built I have generally seen them outdoors and its purpose was to power a water feature. The switch is utilized to energize and d-energize the outlet on the same device and finally the water feature is plugged into the receptacle. In older homes this outlet & switch combo is used in bathrooms. The switch portion of the device controls the bathroom light and the receptacle serves as a general purpose outlet. Here is a very important piece of information before you decide to use this combo device on either of the two scenarios mentioned above. Make sure the circuit you plan to utilize this combination device on is GFCI protected by means of a GFCI outlet or GFCI circuit breaker. But what if their is no GFCI protection what do you do then? Installing a GFCI receptacle & Switch combo is the solution. This device will perform the same functions as the previously mentioned but will provide the necessary GFCI protection.
