Seen in Shaare Tzedek Hospital, Jerusalem:

The white outlets are part of the ordinary hospital circuitry.

The brown outlets lead to the grama circuit, an electrical system designed to indirectly close circuits on the Jewish Sabbath — not something you’ll find in common home use, but perfectly acceptable for use for the sick. Also on the grama circuit is the call button, so that patients will feel free to call for a nurse even if they don’t have an emergency (for an emergency, anything will do, of course).

Not shown are the red outlets, on the emergency generator circuit, and often designed to accept hospital equipment only.
