I have a mechanically held contactor that is being used for a building automation system along with two wattstopper TS400 overrides wired in parallel (not a true 3-way). The TS400 switches require an unswitched hot and a switched hot. The unswitched hots will tap into the incoming hot (from panel) in the contactor. The switched hot needs to tap off of the switched wire coming off of the contactor. A ground wire also goes to each switch and the load (a row of lights) will get a switched hot, a neutral, and a ground. The TS400 switches are located at opposite ends with the row of lights in between and the contactor is located near one of the TS400 switches.
To save running a tap wire all the way back to the contactor through the lighting load from the opposite switch, is it ok to tap off of the switched hot in the last light in the row or do I have to tap off of the switched hot at the contactor.
This isn't an issue with the nearest TS400 switch because I can make a short run to tap both the unswitched hot and the switched hot.
The purpose of this scenario is to allow two switches to be able to turn on lights if they were turned off by the building automation system.
Also, is this a clean way of wiring these types of switches or is it best to run seperate runs between the contactor and the TS400 switches and then out to the lighting load?
I appreciate any feedback. Thanks.
