Dominica Power Plugs, Wall Sockets & Electrical Outlets
In Dominica, power plugs and sockets (electrical outlets) of Type D (BS 546, three large round pins in triangular pattern, grounded) and Type G (BS 1363, three rectangular pins in triangular pattern, grounded) are used. Wall sockets run at 230V and 50Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to Dominica.

Dominica Electrical Outlets Explained
A Dominica power plug typically comes in one of two shapes, since the island uses both Type D and Type G outlets. Type G, the British BS 1363 standard, is the more commonly encountered connector, featuring three rectangular pins arranged in a triangular pattern with a built-in fuse for added protection. Type D, based on the older BS 546 standard, has three large round pins in a triangular layout and is less common but still found in some properties. Visitors should check the electrical outlet at their accommodation in advance, as the two plug types are not interchangeable without an adapter.
Grounding and the Earth Pin
Both plug types used in Dominica are grounded, meaning appliances with a three-pin plug top benefit from an earth connection that reduces the risk of electric shock. On a Type G plug, the longer top pin is the grounding pin, and it also triggers the socket's protective shutters as it is inserted, ensuring the earth connection is made before the live and neutral pins engage. Type D plugs similarly include a larger grounding pin, distinguishable by its bigger diameter compared to the live and neutral pins.
Where to Buy a Travel Adapter for Dominica
Travel adapters for Dominica are widely available at airport shops, electronics retailers, and travel goods stores before departure, as well as online marketplaces that stock universal adapters covering both Type D and Type G configurations. Many hotels in Dominica also keep a small supply of adapters for guests who arrive without one, though availability cannot be guaranteed. Buying an adapter ahead of your trip ensures you can charge devices as soon as you arrive.
Electrical Standards in Dominica: Voltage, Frequency & Plug Type
Dominica runs on a 230V supply at 50Hz, in line with most Caribbean and European electrical systems. This means travelers from countries using 100-127V, such as the United States or Canada, should check whether their devices are dual-voltage before plugging them in, since using incompatible equipment without a converter can cause damage.
- Voltage: 230V
- Frequency: 50Hz
- Plug Type D: Three round pins, grounded, 5A, 220-240V
- Plug Type G: Three rectangular pins, grounded, 13A, 220-240V, with internal fuse protection
Frequently Asked Questions
Yes, if your home country uses a different plug shape than Type D or Type G, you'll need an adapter to fit Dominica's outlets. Since the island uses both plug types, it's worth carrying a universal adapter that covers each configuration.
Dominica operates on a 230V supply at a frequency of 50Hz. Travelers from regions with lower voltage systems should confirm their devices are compatible or use a voltage converter.
Pack a travel adapter compatible with Type D or Type G plugs, since both are used across the island. If your electronics aren't rated for 230V, a voltage converter is also recommended to avoid damaging sensitive devices.
Yes, both Type D and Type G sockets used in Dominica include grounding. The grounding pin on each plug type provides an earth connection, adding a layer of safety when using appliances and electronics.
