Solution for Adding a Fixture to Existing 3-Way Switches

[ad#block]Electrical Question: I have three way switches at the top and bottom of my stairs. There is a light at the top of the stairs controlled by the switches and I wish to add a light at the bottom. A 14/2 runs first to the light at the top (hot and neutral from the breaker), then a 14/2 runs to the switch at the top (hot supply and switched hot back to the light), and a 14/3 runs between the switches (travelers and switched return). It would be very difficult to run a new 14/2 (switched hot and neutral) from the light upstairs to the light downstairs, but it is easy to run a 14/2 from the downstairs light to the switch box downstairs.I want to know if it is acceptable to connect the hot switched from the downstairs 3 way to the light and run a separate neutral to the breaker box, or another nearby circuit’s neutral.

Skill level: electrical engineer and homeowner, but not an electrician. I know how to not burn the house down, but don’t know the electrical code.

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

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 that I use to easily Detect 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.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
