PLUGS AND SOCKETS TYPES
1. A plug is a mobile connector connected to an electrically operated device,
2. The socket is attached to the equipment or structure of a building and connected to an energized electrical circuit.
3. The plug is a male connector with protruding pins that match the openings and female contacts on a plug.
4. Some plugs have female contacts that are used only for a ground connection.
5. Some plugs have built-in fuses for safety.
APPLICATION USES
Plug and socket designs have been gradually developed to reduce the risk of electric shock and fire. Plugs are shaped to prevent finger contact with live parts, and plugs may be recessed. Some types may also include fuses and switches.
TYPES OF POWER PLUGS AND SOCKETS USED BY COUNTRY.
There are currently 15 types of electrical outlet plugs in use today
The Type A electrical plug (or flat blade attachment plug) is an ungrounded plug with two flat parallel pins.

The Type B power plug has two flat parallel pins and a round landing (or earth) pin. The earth pin is longer than the other two, causing the device to land before the power is connected
The Type C electrical plug is a two-wire plug that has two round pins. It fits into any socket that accepts 4.0 – 4.8 mm round contacts on 19 mm centres
The Type D electrical plug has three large round pins in a triangular pattern.
The Type E electrical plug has two 4.8 mm round pins spaced 19 mm apart and a hole for the socket's male earthing pin.
The Type F electrical plug (also known as a Schuko plug) has two 4.8 mm round pins spaced 19 mm apart.
The Type G power plug consists of three rectangular blades in a triangular shape and a built-in fuse (typically 3 amps for small devices such as the computer and 13 amps for heavy-duty devices such as heaters).
The Type H plug is unique to Israel and has two flat pins in a V-shape as well as a grounding pin
The Type I plug has two flat pins in a V-shape as well as a grounding pin. A version of the plug, which only has the two flat pins, exists as well.
The Type J plug has two round pins as well as a grounding pin
The Type K plug has two round pins as well as a grounding pin.
There are two variations of the Type L plug, one 10 amp and one 16 amp. The 10 amp version has two 4mm thick round pins spaced 5.5mm apart, with a grounding pin in the middle. The 16 amp version has two 5mm thick round pins, 8mm apart, as well as a grounding pin.
The M-type plug has three round pins in a triangular pattern and resembles the D-type Indian plug, but its pins are much larger. M-type plugs are sometimes used for larger appliances
There are two variations of the Type N plug, one with a 10 amp rating and one with a 20 amp rating. The 10 amp version has two 4mm thick round pins and one grounding pin. The 20 amp version, used for heavier appliances, has two 4.8mm diameter round pins and one grounding pin.
The O-type plug and socket, with a capacity of 16 amps, are the official standard in Thailand. The plug system was designed in 2006, but its use is not yet widespread.
