Electric Wiring for AFCI in a Home

Brian in Michigan asks: Can residential circuits dedicated to lighting with AFCI light switches share neutrals with other dedicated lighting circuits with AFCI light switches?


Install New Wiring for AFCI
Electrical Question: Can circuits dedicated to lighting with AFCI light switches share neutrals with other dedicated lighting circuits?

Can residential circuits dedicated to lighting with AFCI light switches share neutrals with other dedicated lighting circuits with AFCI light switches?
Note: I want to avoid using AFCI breakers at the Service Panel.
I’ve learned circuits containing any GFCI’s cannot share neutrals with other circuits, but cannot find this answer pertaining to AFCI circuits. This will determine whether I can run 3 wire cable or have to do like my outlets and run separate 2 wire cables for every circuit.

This electrical wiring question came from Brian, a Homeowner in Walker, Michigan.

Dave’s Reply:
Thanks for your electrical wiring question Brian.

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.
