A job I'm working on I have a men's and women's bathroom next to each other. The lighting in them are both run off the same 120v circuit. Plans call for the roof top exhaust fan that exhausts both bathrooms to turn on when either one of the lights are turned on in either bathroom. The exhaust fan is also run off the same 120v circuit as the lights. What would be the best way to accomplish this? Can't think of any way to do this without back feeding one bathroom when the other is turned on. Unless there is such a thing as a contactor with two separate coils in it? Bathroom light switches are also fed from a line voltage occ sensor in the ceiling of each bathroom.
