Is this as simple as screw green(120v) wire to box, black to black, red to orange and cap the other green? There is that white wire in there confusing me. I'm not clear on the whole neutral, or to hot wire thing.
Thanks for any help.
oh yea it's conduit in there. |

It looks like you are trying to replace a single pole switch with some sort of smart switch, an IR detector or timer perhaps?
A single phase smart device needs power (Black (hot) White (neutral) with Red being the switched output. Green is safety ground. From your picture is looks like there are two greens labeled 277V and 120V. Looks like the device is designed to work on 3-Phase and single phase power.
It would be helpful knowing what it is you are trying to do and the device you are adding. If this is a commercial building you should not be doing the work yourself unless you are a licensed electrician.

Ignore the white wire. It appears to be connected correctly.
Turn off power prior to working on the devices for safety reasons and to avoid damage to the component you are installing.
So, connect appropriate green and insulate the other, then red to red, and black to black.
Conduit is required in residential building over three stories by Code, and in some localities even for single story buildings.

It is a motion sensor switch that is on a timer. You can over ride the motion detector by pushing the button for on/off. I'm putting one in my garage because everyone leaves the light on and it drives me crazy. I'm also going to put one in the laundry area in my basement because there are no windows and the wife has her hands full when she goes in there. Conduit is code here unless you do the work yourself, then you can use greenfield or romex. Sorry about the delay I posted this right before I left for work this morn. Thanks for verifying John G. |

That's kind of odd. Looks like this particular device gets it's power from HOT and GND, rather than HOT and NEUTRAL. I have no idea what the codes are on usage of the ground wire, but isn't it never to be used as a current-carrying conductor? Maybe there are exceptions for low-powered devices like smart switches? |

said by tschmidt  :From your picture is looks like there are two greens labeled 277V and 120V. Looks like the device is designed to work on 3-Phase and single phase power. Its a single-phase device and works on single-phase only. Its designed to work on two different voltages. As we know, 277V is very common for the lighting systems in commercial buildings.
A lot of lighting switch-type devices must use their connection from hot to ground to supply a little bit of power. I have seen this on many pilot-light and night light type snap switches. Must play some havoc when you have them on a GFCI breaker. I wonder if its UL listed? |
