Rating of Two pin socket
5 A, 250 V
15 A, 250 V
15 тАУ 200 A, 400 V
All of the above
5 A, 250 V
In Indian electrical domestic wiring standards (IS 1293), a two-pin socket is rated for low-power applications with a standard current carrying capacity of 5 A at 250 V AC. These sockets are designed for appliances that do not require an earthing connection, such as small mobile chargers or LED lamps.

The socket functions as a female connector providing an interface for male plugs to access the electrical supply. The internal copper alloy contacts provide a mechanical gripping force on the plug pins to maintain low electrical contact resistance, ensuring the current I=VPтАЛ remains within the safe thermal limits of the socket housing.
Standard domestic voltage in India is 230 V - 250 V.
2-pin sockets lack the protective earth (ground) terminal.
Higher power appliances (e.g., heaters) use 15 A / 16 A 3-pin sockets.
Compliance follows IS 1293 standard for plugs and socket-outlets.
Compact physical footprint
Cost-effective for low-power devices
Lack of earth terminal increases safety risk for metallic appliances
Not suitable for heavy-duty appliances
Mobile phone chargers
Small portable fans
Table lamps
The 15 A rating is reserved for heavy appliances like geysers and AC units, which mandate a 3-pin configuration for safety.
Option B (15 A) typically corresponds to the larger 3-pin socket format.
Option C (15-200 A) refers to industrial-grade power distribution and is far outside the scope of standard domestic 2-pin sockets.
A is correct тАФ The standard rating for a two-pin socket in domestic electrical wiring is 5 A, 250 V.
Always remember that the earth pin in a 3-pin plug is thicker and longer than the live/neutral pins to ensure that the earth connection is established before the power connection.
