It's also known as a "multi-output plug," a "three-way plug," or a "Trishul plug and socket" because it serves multiple purposes. One end is the plug end, where the socket can be engaged, and the other end often has 2 or 3 openings, which is the socket end, where the plug can be engaged and power supply can occur. They're common on civil and mechanical construction sites like road construction and bridge construction when numerous machines are working at the same time.
