Modern electrical systems cannot function properly without electric plugs and sockets, which enable the connection of electronic devices to power sources. Various plugs and sockets are created according to the specific design and voltage requirements. The wide range of plugs and sockets can charge electronic devices and power appliances around the house. Moreover, these plugs and sockets are embedded with numerous advantages such as convenience, security features and compatibility with a variety of devices. In general, electric plugs and sockets are essential for providing power for our daily needs while maintaining efficiency and safety.

What are Electric Plugs?

The devices that provide and draw current from a container to an electrical appliance's circuits are called electrical plugs, also referred to as power plugs. In a typical electric plug, the prongs or pins are held up by a plastic case. To create an electrical connection between an appliance and the main power source, prongs are placed into the gaps of an outlet or receptacle.

Types of Electric Plugs

There are at least 15 standard varieties of electric plugs currently available in the market. Let us take a look at some of the widely utilised electric plugs:

Type A

Unground plugs with two parallel, flat prongs are known as type A plugs. The voltage and current ratings for these plugs are 125V and 15A, respectively. Plugs of type A fit both Type A and Type B sockets.

Type E

Two round pins make up Type E electrical plugs. They feature a 14 mm long by 4.8 mm diameter female interface or hole that takes the earthing pin from the socket. Underneath the plug pins lies this contact. Due to their asymmetric pin layout, Type E plugs prevent polarity reversal.

Type C

The most commonly used electrical plug worldwide is type C plug. It has two spherical pins and is an unpolarised and ungrounded plug.

Type F

Except for their imperfectly shaped pins, Type F plugs are nearly identical to Type E plugs in terms of pin diameters. Two earthing clips in Type F plugs replace a female earthing contact. To give even more stability when utilised as an enormous built-in plug, these plugs also feature two plastic notches on both the right and left sides.

Type B

Plugs with type B are commonly referred to as the three pin plug and recognised as grounded plugs. They are made up of a spherical grounding pin along with two parallel flat prongs. Type B electrical plugs' current and voltage ratings are 15A and 125V, respectively.

Type G

Three rectangular pins arranged in a triangle create Type G plugs, including an integrated fuse. Fuse ratings of 3A or 13A are included with Type G plugs. Type G plugs are frequently used in heavy-duty appliances due to their higher current rating. For this reason, Type G plug and socket arrangement is considered one of the safest tools for the equipment and the user. The only disadvantage of Type G plugs is that they are only compatible with Type G sockets, which further indicates that they cannot be used with other types of sockets.

Type K

Two circular pins, including a U-shape earthing pin, are known as type K electrical plugs. The gender and structure of the earthing connection on these plugs differ from those of Type E plugs. The construction of Type K plugs prevents polarity reversal and is embedded with a current rating of 16A.

Type D

Three circular pins arranged in a triangle shape are known as Type D electrical plugs. Type D plugs are shielded against polarity reversal due to their asymmetrical pin layout.

Uses of Electric Plug

The main use of an electric plug is to draw electricity to allow various appliances to perform their functions. Besides that, there are multiple uses for an electric plug, which are given below:

• Multiple appliances such as TVs, washing machines, microwaves, and refrigerators are connected to power sources for electricity via electric plugs.

What are Electric Sockets?

The conduit that permits electricity to flow into electrical gadgets and machinery is known as the electric socket. An electric socket is considered one of the crucial elements in conducting electricity. Although there may be a difference in the sizes and designs of various electric sockets throughout several nations, their primal functionality remains the same. Another factor that sets sockets apart is their voltage capability or the maximum amount of current they can handle.

Types of Electric Sockets

Among the wide spectrum of electric sockets, here are some of the widely popular sockets used in the world:

Two Pin Electrical Outlet

In residences, 2-prong/pin outlets are frequently installed and are exclusively meant for ungrounded circuits. The majority of the time, they are still used for low-power home appliances that need low voltage or low current.

Three Pin Electrical Outlet

The modern standard for outlets in homes and workplaces is the 3-prong/pin electrical socket. It is becoming acceptable to use these sockets for ordinary light electrical use at home while taking the role of the 2-prong outlet. These three-pin grounded outlets are far safer than two pin outlets.

AFCI Outlets

AFCI outlets function to prevent arcing and the potentially dangerous effects of the intense heat the arc creates. The AFCI outlet detects arcing and instantly deactivates the outlet via an inbuilt breaker.

GFCI Outlets

GFCI outlets are utilised in laundry rooms, restrooms, kitchens, basements, and outdoor spaces in your house where there is a constant presence of water. The operation of the GFCI outlet is quite simple.
