Sal in New York asks about Wiring 3-Way Switches
Question on wiring, there are three switches in a 3 gang box. The switches control a ceiling fan (bathroom), a shower light and the last switch a main bathroom light. The black wires are connected to the switches, the white are all connected, the ground are all connected. There is a black wire that connects to the top screw pig tailed to each switch. Then from this box a 12/3 wire goes to a GFI outlet that has black and red connected to one GFI screw and a white to another screw. In the three gang box the original switch the red and black (pigtail) are connected together. Is this a correct way? As I am relocating the GFI and main 3 gang box to a four gang box. The four gang box will have the three switches and a GFI outlet. Do I still need the 12/3 wire as I note how it is now connected?
This electrical wiring question came from Sal, a Handyman, in Stony Point, New York.
Hi Sal, Great Question!
Yes, the 12/3 wire that goes to the GFCI outlet should be wired the same way inside the new 4 gang box.
All of the wiring remains the same, only the wiring will be contained inside one 4 gang box, therefore make sure to carefully mark the wires to ensure the same connections as originally found, and make sure the size of the new 4 gang box will have the space for all the wires.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
