Relative clauses give us information about the person or thing mentioned.
Non-defining relative clauses give us extra information about someone or something. It isn't essential for understanding who or what we are talking about.

Rules to use
1- We always use a relative pronoun or adverb to start a non-defining relative clause: who, which, whose, when or where (but not that). We also use commas to separate the clause from the rest of the sentence.

A) who, which and whose
Rule 2-We can use who to talk about people, which to talk about things and whose to refer to the person or thing that something belongs to.

3- My next-door neighbour, whose children go to school with ours, has just bought a new car.
4-After the port there is a row of fisherman's houses, whose lights can be seen from across the bay.
B)Places and times
We can use which with a preposition to talk about places and times. In these cases it's more common to use where or when instead of which and the preposition.
