I didn't really know were to post this, because It is a code question and what you guys do out in the field.
When is it required to use 3 way switches in rooms? Does every entry into the room need a switch for the light?
I am looking at a 8500sft house and the prints do not have any electrical on them. I am trying to mark the print for the electrical. Lots of the rooms have three to four ways to enter. Would you guys install 3or4 way switches at every entry point?
