I have a hallway I want to light when you walk into it. Bought a motion detector light switch. It has four wires. Hot (black), Neutral (white), Switched (red) and Ground(green). Inside the box there is only one black wire and one white wire. I KNOW the wiring is "Interrupt". Which means hot goes to the lamp. From the lamp it goes to a switch. From the switch it goes back to the box and joins with the neutral. There is no ground. And though technically it's a neutral switched side, is there any way I can use this detector?
