Question about Cooper Wiring Devices Electrical Supplies
Two "cooper wiring devices" "390-6107XX-EG1D" occupancy sensors in a circuit at the top and bottom of a stairway.which are generating huge amounts of noise in the AM radio band. All the time its "ON" (has turned on the lights) the AM radio generates nothing but noise. (I have tested by removing all other items from the circuit. Even when they are the only thing in the circuit, when they are "on' they still makes noise. Both are grounded to metal conduit. Is there anyway to stop the static?

Correct, assuming red and black are connected to the breakers in the breaker panel, and white is connected to the neutral/ground buss bar in the breaker panel.

Testimonial: "I guess they didn't bother to check the instructions. I Just went ahead and wired it the way I thought it should be wired and everything worked fine"
SOURCE: i just bought a switch
The key seems to be that you changed wiring in the ceiling box.
I suggest you make a drawing of the wires before and after. Track the route that the Hot wire takes.
The key question is this: Does Hot wire from breaker box arrive in the ceiling box first? Or does it arrive in wall box first?
I think Hot from breaker arrives in wall box first. And from there Hot wire goes to ceiling box ... and from ceiling box the hot wire goes to other plugs in room. If this is true, you will be one wire short for installing fan control switch.
I always make a drawing of existing wires before starting, so I can put it back the way it was. It sounds like you got a good handle on which wire goes where.
We used to solve the one-wire-short problem by making a simple project bigger. Figure out which direction ceiling joist run. See if you can slide fish line from fan ceiling box over to wall. If that works. Over at the wall, chop small hole in ceiling so you can feed wire up to fish line. Pull wire over to ceiling box. Next, staple other end of wire along ceiling over to location above wall box. Chop another small hole so you can feed wire down to wall box. And then install beautiful crown molding to hide the mess, and paint the room so you need new furniture.

Use only incandescent light bulbs on those and test again.
