Countries & Territories Using Type D
Type D is officially deployed in the national grid or hotel accommodations of the following countries:
The mechanical architecture of Type D is defined by Earth pin 7.06 mm diam (20.6 mm long); Live/Neutral 5.08 mm diam (14.9 mm long). Sockets engineered for this standard operate at nominal capacities up to 5A.
When traveling with equipment utilizing this plug, verify that the foreign receptacle is compatible with its physical grounding structure. Using 3-to-2 prong grounding cheater adapters can remove protective earth bonding, exposing metallic device housings to live chassis fault risks.
