Are there different types of electrical outlets?
Another commonly used electrical outlet in U.S. is the 20A 120V outlet. The receptacle looks slightly different from the 15A outlet with a small horizontal slot branching of a vertical slot. Also, the 20A outlet uses a 12-gauge or 10-gauge wire with a 20A breaker.
What’s the difference between an outlet and receptacle?
An outlet is defined as “A point on the wiring system at which current is taken to supply utilization equipment”. A receptacle however has always been something that an attachment plug is connected to. With the introduction of new products comes the need to revise certain code definitions.
Does it matter if you use a 15 or 20 amp outlet?
You can use a device that has a 15-amp plug with either a 15- or 20-amp receptacle. Standard 15-amp receptacles are suitable for typical household appliances, lamps and other accessories. A 20-amp receptacle is for heavy-duty appliances and power tools, such as air compressors.

9 Types of Electrical Outlets You Can Have in the Home
- 15A, 120 Volt Outlets. These are the most common in older homes and come in two versions:

Are all electrical receptacles the same?
Most homes in the U.S. are wired with a combination of 15-amp and 20-amp, 120-volt circuits. Because 15-amp receptacles can be used with 20-amp circuits, most of the outlets you see in American homes are the standard 15-amp variety, with two slots and a U-shaped grounding hole.
Are sockets receptacles?
A socket is something into which something is plugged or fitted (also called a receptacle). An outlet is something that something comes out of. A light socket is called a light socket because a light bulb is inserted into it.
Can lights and receptacles be on the same circuit?
Yes, you can. The average home uses an indoor distribution board that houses the breakers of the majority of circuits in the home. A circuit controlled by a 15A circuit breaker (which a lot of contractors use for general lighting) can also accommodate outlets.
Why do we have different types and configurations of receptacles and plugs?
The National Electrical Manufacturers Association (NEMA) has assigned designations to the various configurations. The purpose of so many different types is to prevent the wrong combinations of electrical systems from being plugged together, thereby avoiding potentially dangerous conditions.
Why are there holes on plugs?
These bumps fit into the holes so that the outlet can grip the plug’s prongs more firmly. This detenting prevents the plug from slipping out of the socket due to the weight of the plug and cord. It also improves the contact between the plug and the outlet.
