I am currently wiring my detached garage. The garage is in the backyard about 12' from the house. There is a porch light attached to the house with a switch just inside the back door(Original.Gif). My current plan is to change the existing regular switch to a 3way switch, run a 14.3 cable from the switch box, down to under the house, out the side of the house and into the ground, over to the garage, up and into the wall, to a 4way switch and then another 14.3 cable to a second 3way switch(Planned.Gif). I would like to add a second light after the second 3way switch(Modified Plan.Gif).
My questions are 1) Will all three switches turn on/off Both lights? and 2) Is there something about this wiring that could be dangerous or against code?
Thak you in advance for your help.
