Three round pins in a triangular layout. Type D and Type M are different sizes. Never force either plug into the other socket.
Fit is not a safety verdict
Type D and Type M are different sizes. Never force either plug into the other socket.
Type D shape and grounding
Three round pins in a triangular layout. This overview describes a family, not a manufacturing drawing. Exact pin dimensions, current rating, polarity and national certifications depend on the variant.
| Typical shape | Three round pins in a triangular layout. |
|---|---|
| Protective earth in grounded variant | Yes, if the correct contacts and wiring are present |
| Standard references | BS 546 small pattern, IS 1293 |
| Known variants | D_BS546_5A, D_INDIA |
Type D variants and ratings
A family can contain different national or current-rated variants. The values below are reference identifiers, not permission to use a particular manufactured plug at that load. Read the exact product marking and local standard.
| Variant | Reference current | Earth contact |
|---|---|---|
| D BS546 5A | 5A | Present in variant design |
| D INDIA | Not established | Present in variant design |
Plug-to-socket direction matters
These research rules start with a male appliance plug and end at a wall socket. Reversing the route can change the result. Even a documented family fit needs an intact installation and the device voltage, frequency and current checks.
| Device male plug | Wall socket | Reference result | Earth path |
|---|---|---|---|
| D BS546 5A | D BS546 5A | same standard variant conditional | Documented conditional contact |
| D INDIA | D INDIA | same standard variant conditional | Documented conditional contact |
| D BS546 5A | M BS546 15A | not interchangeable | Not preserved or unverified |

How to check a connection
- Identify the exact male plug on your appliance and the socket in the room.
- Check the adapter input and output variants, not just the Type D label.
- Compare AC input voltage, frequency, protective earth and the lowest current rating in the chain.
- Stop if a pin must be forced, the connection is loose or the manufacturer excludes the appliance.
