I'm looking at 210.70 and don't see a requirement for 3 way switches in a residential hallway. Is it somewhere else or is there not a requirement?
And, technically, that switch need not even be in that room, nor by a door.The same with other types of rooms as well, you could have a living room with 4 entrances and all that the NEC requires is one wall switch controlled lighting outlet.
I always put three ways in hallways but I inherited a job that is already roughed in and rocked and no threes to be found.
You could fish in a dead end 3 way if attic above or simply do without.I always put three ways in hallways but I inherited a job that is already roughed in and rocked and no threes to be found.
Only location requirement that I'm aware of for three ways is 210.70(2)(c) but that is for more than six steps. 210.70 covers the whole issue.
Are dimming switches required in residential. Is there a code stating some sort of requirement if there is?

Some state and local energy codes require it, but nothing in the NEC.Are dimming switches required in residential. Is there a code stating some sort of requirement if there is?
