The mechanical architecture of Type I is defined by Two flat pins (6.5 x 1.6 mm) inclined at 30° to vertical; ground pin (6.5 x 1.6 x 20 mm). Sockets engineered for this standard operate at nominal capacities up to 10A / 15A.
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.
