I’m installing two new ceiling fans below an existing ceiling that cannot be disturbed because it’s decorative, so I’m framing a new drop ceiling cavity consisting of 2x4s to run 14/3 cable and set the two fan junction boxes with steel brackets.
Can I run the cable loosely in this space, connecting only at the boxes, or does this wiring have to be secured somehow? I'm in Kansas and NEC applies.
If you can get to the areas, and not running cable through a cavity, the wire needs to be anchored. Since you said you are framing in a new ceiling you need to follow the code for new construction. Staple the wire 8 inches from the box minimum. and every 4 1/2 feet.
Your choice of cable should be rated for the breaker that services it. #14 for a 15 amp breaker, #12 for a 20 amp breaker. The reference from another member to 12/3 cable is good advice. The 12/3 will give wire to power the fan and a light separately. A good idea even if the new fan does not have a light, the wire is there for the future. The 12/3 can be used with a 15 or 20 amp breaker.
