This is one of the task some people look at and tend to think it would be easy to wire. It is an easy task looking at it on paper. But after the wire is pulled is where the confusion begins. If you pull the switch leg off one three-way and the feed wires on other three-way it’s much easier to keep track of your connections. The complexity comes into play when the switch leg is pulled from the same box as the feed wires (neutral & Hot). Keep your feed and switch led on opposite three-ways and things are much easier to figure. If you can wire a 4-way light switch circuit and you are not an electrician then you are one of the elite. If you need to ask a question make sure you have all your 3 wire pulled so we can get your lights going today.
