There are two different ways to wire in 2 duplex outlets: Split Duplex or Split Wired Receptacle: With this type of installation, two separate receptacles are installed in one location (double gang box). Each receptacle has its own power source, and is wired into a separate breaker.
What is the difference between a duplex outlet and a regular outlet?
A duplex outlet has two receptacles to use for power. A duplex receptacle outlet is very similar to a single outlet where it can be TR, WR, or both! Duplex receptacles have different amperages and can handle different amounts of power, so make sure to pay attention to the “Amps” your outlet can handle.
What are convenience outlets?

How do I know what kind of outlet I have?
Tip: The easiest way to determine whether a circuit is 15 or 20 amps is to look at the corresponding breaker or fuse in the breaker panel. Dedicated circuits are electrical lines that carry an electrical current to one single outlet.
What happens if you put a 20 amp outlet on a 15 amp circuit?
First off, connecting a 20 Amp load to a 15 Amp circuit will overload the circuit but shouldn't cause a fire because the 15 Amp breaker will trip. A 20 amp GFCI doesn't pose any threat just by being there.

A small metal tab between the terminal screws can be removed on both sides to split the two receptacles for independent wiring.
What is an outlet?
An outlet is any point on the electrical system where power is intentionally made available (see Glossary). One example is lighting outlets, which are the boxes in the ceiling from which lighting fixtures are powered. Another example is receptacle outlets, which contain one or more receptacles. A convenience receptacle, also known as a convenience outlet, is the type of straight-blade receptacle that we use every day to plug in our toasters, computers, vacuum cleaners, et cetera. A duplex convenience receptacle has two such receptacles, as opposed to a single or simplex receptacle, which has only one receptacle. There are other types of receptacles that are not considered to be convenience receptacles, such as dryer receptacles in residential laundry rooms and welding receptacles at commercial and industrial facilities, but they are not included in the topic of this course, which is duplex convenience receptacles.
How often do you plug in a receptacle?
Most of us plug something into a receptacle at least once a week, and many of us do so on a daily basis. Receptacles are so commonplace that they are often beneath our notice. The topic of duplex convenience receptacles might seem like an easy one, and it is, but there are many questions and misconceptions about these ubiquitous devices that will be addressed in this course. Some of those questions include:
What is the shape of the neutral openings for a 20A and 15A receptacle?
Notice that the 15A hot and neutral openings are both straight, but the neutral opening for the 20A receptacle has a different shape that makes the opening look like a sideways T. This T shape will admit a 5-20P plug, as well as a 5-15P plug. See Figure 2 for the arrangement of a NEMA 5-20P plug. You would use a 5-20P plug if you had an appliance or piece of equipment that required a circuit that was more than 15A, but for which a 20A circuit was acceptable. In other words, you would not be able to plug the appliance into a 15A circuit (assuming the circuit had only 5-15R receptacles installed on it, as is proper) because the 20A plug will not fit into the 15A receptacle. The shape of the neutral opening of a 5-20R receptacle, however, will accept a 15A plug or a 20A plug, which makes sense, since this type of receptacle should only be installed on a 20A circuit, not a 15A circuit.
What is the prefix for a 5-15R plug?
Let’s consider the NEMA 5-15R and 5-20R designations. The 5 prefix defines the arrangement, physical size, and orientation of the receptacle connections that we are all familiar with. The -15 and -20 indicate the amperage rating of the plug connections, but the feed-through amperage rating (see Glossary) for a receptacle is typically 20A for both 15A and 20A receptacles (always confirm with the specific product information). The R suffix means it is a receptacle (female), whereas a P suffix would indicate a plug (male). In other words, a NEMA 5-15P plug would fit a NEMA 5-15R receptacle. As we will see later, a 5-15P plug will also fit a 5-20R receptacle, but a 5-20P plug will not fit a 5-15R receptacle.
What is the difference between a NEMA 1-15P and a 3 wire plug?
Notice in Figure 2 that the 2-wire, non-grounding NEMA 1-15P plug has a larger neutral blade for proper alignment of the polarized connection while the 3-wire, NEMA 5-15P grounding-type plug has a neutral blade and hot blade of the same size. This is because the ground pin of the 3- wire plug will assure proper alignment, which is another reason to never cut off the ground pin of a 3-wire grounding-type plug. With the ground pin removed, most 3-wire plugs would be left with a non-polarized arrangement that could be inserted in either orientation.
What are the faces of receptacles?
The faces of receptacles can be the rectangular Decora or decorator type, such as the isolated ground receptacle in Figure 11 and Figure 14, or the familiar jack-o’-lantern shape shown as the ‘regular’ receptacle in Figure 11 and Figure 13.
What is a two wire non polarized plug?
Some appliances and other electric devices, such as cell phone chargers, come with two-wire non-polarized 1- 15P plugs. These devices with two-wire non-polarized plugs are usually designed with double insulation or with switches that break both the hot and the neutral.
What is a convenience receptacle?
IMO, convenience receptacles (CR's) are not necessarily NEC general purpose receptacles (GPR's), though many do not make the differentiation. GPR's are CR's placed for occasional use but have no intended loads. However, CR's also include receptacles located for specific loads. For example, you know a hallway will need receptacles for the convenience of plugging in maintenance equipment (vacuum sweepers, floor polishers, etc.). Let's say you have a short carpeted hallway where a vacuum sweeper cord allows reaching the entire area. You place one maybe two receptacles in the hallway. Are you going to calculate each at 180VA??? Are you going to put them on the same circuit as 15 angel other receptacles in office cubicles???
How many receptacles can I put on a 20 amp circuit?
I, for example will generally put 8-10 receptacles maximum on a 20 amp circuit when I am doing a Master Electrician allowed design build.
What is negligent if you don't provide additional circuits?
Regarding branch circuiting, if you know that the loads intended to plug in to one circuit are going to overload that circuit, then you are negligent if you don't provide additional circuits, or document it to the designer. The code is clear that the load shall not exceed the circuit.
Do you need a vacuum receptacle in a hallway?
Let's say you have a short carpeted hallway where a vacuum sweeper cord allows reaching the entire area. You place one maybe two receptacles in the hallway.
Does an electrical engineer place receptacles?
Yea, but the electrical engineer doesn't place the receptacles (at least in my case). The architect places receptacles and the electrical engineer circuits them. So how do I know just by looking at a power plan, which receptacles are considered convenience? The appliance receptacles are listed as per the architect's plans (microwave, dishwasher, etc.) so these are obvious. But what about everything else?
What is the unique design of an outlet?
The unique design of the outlet allows you to easily match it up to the plug of the power tool, not only ensuring that amperage requirements are met but also offering the additional safety feature of preventing you from accidentally plugging any other appliance into it.
How many plug in slots are there in a 240V receptacle?
Providing both 120 and 240 volts, these receptacles have four plug-in slots—two that are hot, one that is neutral, and one that is grounding.
What is a 120 volt GFCI?
Identified by the reset and test buttons located on its face, a 120-volt GFCI receptacle takes the place of a standard duplex receptacle and monitors electric current. It is like a super-sensitive circuit breaker. Whenever the amounts of incoming and outgoing current are not equal, such as during a ground fault or current leakage, the GFCI will sense the problem and shut down itself or, in some cases, other receptacles on the same circuit.
What is a GFCI receptacle?
GFCI Receptacles. A special type of receptacle called a GFCI (or GFI), short for ground-fault circuit interrupter, is required in kitchens, bathrooms, and other exposed, damp areas of a home to protect from the serious shock that can occur where electricity and water meet.
How many hot slots does a 240V outlet have?
Unlike standard three-prong outlets, which have a neutral and a hot slot in addition to the arch-shaped grounding slot, a 240-volt receptacle has two hot slots in addition to the grounding slot.
What is the difference between a neutral and a hot outlet?
Each outlet has an arched slot at the bottom that grounds the appliance; above that are two narrow slots— the wider one is neutral and the narrower one is hot. Check the amperage and voltage requirements of the appliance you intend to plug in to the outlet against the amperage and voltage of the outlet, which are clearly shown on the front of the outlet itself.
What voltage is a conventional receptacle?
This article discusses conventional 120-volt and 240-volt receptacles. For additional information, also see Electrical Receptacle Buying Guide.
What is the rated voltage of a convenience outlet?
A convenience outlet will be rated either for > 10 A / 15 A. It will be a 3 pin format, multi plug format and it may accept only a 3 pin plug.
What is the difference between 3 sockets?
All 3 are sockets, receptacles where appliances and devices can be “conveniently”, plugged in for their eventful use. They are also terms generated by the electrical world, to define them so that it becomes easy to segregate different loads, for planning, design and installation.
Why use #12 wire?
If there is any chance you will need more capacity in that circuit later, using #12 wire will give you that by changing the receptacle and breaker .
What are all 3 sockets?
All 3 are sockets, receptacles where appliances and devices can be “conveniently”, plugged in for their eventful use. They are also terms generated by the electrical world, to define them so that it becomes easy to segregate different loads, for planning, design and installation.
Do you have to replace a plug on an appliance?
You may (well, ok- you *will*) need to replace the plug on the appliance. No licensed electrician in the US will cut off the manufacturer’s European-style plug and put on another. Matter of fact, I’ve heard of cases where replacing a US plug on a worn cord ($3.00 part) leads to liability issues- so the entire power cord must be replaced (at least 10x more cost for the part, because it’s a “manufacturer’s approved replacement”).
Do you need jacketed cable between a switch and a receptacle?
Also, if the switch and the receptacle are both in the same junction box, you obviously don’t need to run jacketed cable between the two devices - single conductors (properly color-coded) of the appropriate wire gauge and insulation are acceptable.
Can you plug a 220 volt welder in a random socket?
So….in ( http://So….in) North America, you cannot take your 220 volt arc welder or pottery dry kiln and plug it in to a random socket in your bedroom or living room. The code is designed to make it difficult for an enterprising but ignorant homeowner to modify the external plug, connecting or extension cord or appliance to access greater, more dangerous currents than the built in system was designed to deliver.
