Q. Is it permitted to reset a main fuse in an apartment building at dinner time. It’s a Sufik D’orisa if people may have pots of Bosor B’cholov on their stoves and you are making it cooked.

A. Horav Shlomo Miller’s Shlit”a opinion is that this constitutes a case of a “dovor sheino miskaven” (an unintentional act) when at the same time it is also not a “p’sik reisha” (an unavoidable act), since it is not a certainty that someone in the building will be cooking meat together with milk at that time in a prohibited manner. When these two conditions coincide, it is permitted.
