The common types of sockets used for electricity supply in residential buildings vary across different regions and countries. Here are some of the commonly used socket types:
1. Type A: This two-pin socket with flat blades is commonly used in North and Central America, as well as in parts of South America and Asia.
2. Type B: Similar to Type A, Type B sockets also have two flat blades but with a grounding pin below. They are widely used in North and Central America.
3. Type C: Commonly known as the Europlug, Type C sockets have two round pins and are prevalent in most European countries.
4. Type D: Type D sockets feature three large round pins arranged in a triangular shape. They are commonly used in India, Sri Lanka, Nepal, and some African countries.
5. Type E: Often used in France, Belgium, Poland, and other European countries, Type E sockets have two round pins with a hole for the grounding pin.
6. Type F: The Schuko socket, also known as Type F, is widely used in most European countries. It has two round pins and an additional grounding clip at the top or bottom.
7. Type G: Type G sockets are commonly used in the United Kingdom, Ireland, Malaysia, Singapore, and some African countries. They have three rectangular pins in a triangular formation.
8. Type I: Type I sockets are used in Australia, New Zealand, China, Argentina, and many other countries. They feature two slanted flat pins and an additional grounding pin.
9. Type J: Type J sockets, found mainly in Switzerland and Liechtenstein, have three round pins arranged in a triangular shape.
10. Type K: Type K sockets, mostly used in Denmark and Greenland, have three round pins similar to Type J but with a larger diameter.
It is important to note that these socket types may vary in voltage and current rating across different countries and regions, so it is essential to consult local electrical codes and regulations when dealing with electricity supply in residential buildings.
