Video was exceptional. 3 way switches I had had the dark screw on the same side as one of the brass screws. Mistakenly thought the lone screw was the common. In the wiring book I was using that was how the 3 way switch was diagramed.

Made the change putting the power and load on the dark screw and switches work as expected. Discovered only the 4 way switch was grounded. Corrected situation and now all 3 are grounded. Again, thanks for this useful video.

Great video. Good description. I was wondering about the white commons in my circuit. You answered that right off.

I use my inpact on the 2nd lowest torque setting by rapidly pressing the button. Faster than using a robby handheld screwdriver.

perfect, this is just what I needed -thanks

Neutrals are used in a 3 way switch system, they return current to the panel. I hope that what you meant to say was that they just dont have a place on the switch. But that is the case with all switches in a house.

Also you wore from 14-2, if used 14-3 can I use the blk and cap the first red?

[bigislandtinyfootprinteduc]

Do you need to use 14-2 going to lights?

I wired all 14-3

One question how about the light in the middle how do you wire the four way switch thanks

[bigislandtinyfootprinteduc]

So throwing two four ways between?.. doesn’t change does it..?

[nicks]

Is this method (Power to one end and other end to light) preferred over the (Power to light fixture) method for four way switch systems? Why?

What if I want to install a three way dimmer switch where a four way switch is now I have two black and two red wires and the white are in the box together I have a red wire going to a dark screw and a black wire going to a dark screw and the other two wires black and red each go to the common screw

Cut around your insulation to your wires before you pull through makes the job easier. Easier to cut also when putting wires back in the box.
