Question: I noticed that 12-2 NMB now has yellow sheathing. I have some older 12-2 NMB that has white sheathing. Can I use the white in new construction or do I have to use the yellow?

This electrical question came from: Keith, a Contractor from Port Townsend WA.

Dave’s Reply:
Thanks for your electrical question Keith.

The Standard Types of Home Electrical Cables
Keith, a standard for identifying which wire size or gauge of electrical cable that is used for house wiring has been adopted for the Romex type NMB Cable. Your local building authority may not allow you to install cable that does not conform to the new standard, however you may want to ask them directly since they will be inspecting your wiring project.

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.

    Can I replace the 16/2 braided wire on a whole house fan motor with a 14/2 or 12/2 nm wire? The existing wire does not have a ground wire and the unit is all metal. Thanks!

    • Dave Rongey says:

      Hi Douglas,
      As long as the wire size is the same or larger, 14/2 would be fine and easier to work with than 12/2.
      Attaching the ground wire to the metal frame or ground screw in the connection box if there is one available would be good.
      Dave
