I am planning to install recessed light in ceiling of my 2nd floor condominium. Here are some facts.
There is truss framing (picture attached) in the ceiling, between my ceiling and the upstairs unit's floor.
There is fiberglass insulation in ceiling.
I live in New Jersey and I don't think there is local code in addition to NEC.
I am planning to cut holes in ceiling for can lights and pull the power source from existing switch which currently controls receptacle. I am thinking to change wiring inside the receptacle to make it always hot and then I will connect my recessed lights to existing switch.
I have some questions.
Given truss type of framing in ceiling, can I just run the cables from one can to other can in straight line or I have to run the cable only parallel or perpendicular to framing ?
Is it OK to run Romex cables through fiberglass insulation ?
NEC requires that Romex cable has to be supported to framing members, within ceiling or walls, every 8 inches (I don't remember exact distance) with staples. - How can support it when I don't have access to the ceiling or walls ? I would have to tear apart lot of ceiling and wall to satisfy NEC requirement.
