I’ll try my best to explain and use some modified diagrams.
I recently moved into a new house and will be upgrading all of the switches in the house to Inovelli Red Series Switches and Dimmers (as soon as they ship) with GE Add on switches for 3-4 way switches. The garage is from the 1960s, but the rest of the house was rebuilt in 2000. For all areas not related to the garage, there is a neutral in the box and I’ll be good.
In the garage, there are not neutrals in the box. However, in some of the 2+ gang switch boxes, there is a mix of new and old lighing circuits.
The image below is an example of what some of these look like. The purple rectangle represents a 2 gang box.
For the light that does not have a neutral to the switches, can I “borrow” the neutral from the light that does have a neutral? It would look something like this: where I run the blue wire in the diagram and then use the black traveler as a neutral.
Will this work?
Is this “allowed”?
