Q. See questions (2926-28) above regarding a prosthetic electronic arm. Can one wear and carry that electrically disconnected arm or hand in the street, on Shabbat when there is no eruv?
A. Horav Shlomo Miller’s Shlit’a opinion is that if it was disconnected and is properly attached so it wont fall off and indeed it makes the carrier look normal, it is permitted.
Rabbi A. Bartfeld as advised by Horav Shlomo Miller and Horav Aharon Miller Shlit'a
