How to Upgrade Home Electrical Wiring

Electrical Question: I am redoing part of my house and found some older NM cable.

  • The cable is 2 x 12 gauge and a much smaller ground wire.
  • I am wondering if it is permissible to use the thinner ground wire to add 3 wire outlets or if a heavier gauge ground wire has to be run.

Thanks for your electrical question Eric.

  • Installing 3-Wire Outlets
    • It is OK to use the existing ground wire for 3 wire outlets, however if you are redoing this part of the home you may consider upgrading the electrical wring, especially if the walls are open.
    • Inquire with your local building department and see what is involved with the extent of your project, and what will be required to be included with the upgrade.
