When you’re off to India or Nepal, you’ll soon discover they plug into type D sockets. This unique and distinctive three-pin system is also found in some spots across Africa and South America.
Features of Type D Socket
The type D socket sports a trio of pins set in a triangular formation. The top pin acts as the earth and is notably chunkier and longer than the two below. This layout ensures extra safety, making it a common choice in these regions. So, if your travel itinerary includes destinations like India or Nepal, make sure to pop a type D adaptor into your suitcase to keep all your gadgets charged and ready to go.

Dimensions
The Type D plug features a central grounding pin that’s a solid 20.6 millimetres long and 7.1 millimetres wide. The other two pins are each 5.1 millimetres wide and 14.9 millimetres long, spaced neatly 19.1 millimetres apart.
Using the Type D Plug
Primarily used in India, Nepal, and Pakistan, the Type D plug also makes appearances in select countries across Africa and South America. It’s a relic from the British standards used in the United Kingdom before 1947, which explains why it’s still used in many former British colonies.
A word of caution: Type C, E, and F plugs might seem like they fit into Type D sockets, but don’t be fooled. This can be a risky mix-up, potentially causing sparks, short circuits, and even electric shocks.
Caution: Avoid using Type C, E, and F plugs in Type D sockets!
Type D sockets are predominantly found in India and Nepal, and you might spot them in some British hotels, where they’re typically reserved for specific uses like providing direct current or connecting lamps to switches or dimmers.
The Necessity of a Travel Adaptor
It’s absolutely crucial to pack a suitable travel adaptor that’s compatible with Type D sockets when travelling to these regions. Without the correct adaptor, you run the risk of not being able to charge your devices, damaging your charger, and in severe cases, causing short circuits, electrical shocks, or even fire hazards. It’s clear you’d want to steer clear of these troubles!
