I had this question on a test. How many light switches shall be installed in a basement with 2 entrances. choices where 0,1,2,3 I answered 2 but was concerned between my answer and 1. 210.70 (3) states At least one point of control shall be at the usual point of entry to these spaces. My question did not state which or both was the usual point of entry. I thought this a little misleading. Can anyone confirm, one or two if the question does not specifically state that one or both entrances are the usual point of entry?
