Electrical – strip a neutral wire and use it to pigtail ground wires

electricalgroundingwiring

I need to ground outlets in my house and need to pigtail the ground wires. Just wondering if I can salvage the old neutral wires, strip them, and use them to pigtail to the outlet instead of cutting off extra ground wire.

Best Answer

Yes, as long as they are thick enough (thicker is always OK) and you must strip the whole wire because grounds must be green or bare, not white or any other color. If you are concerned about the ground wires shorting against screws, put tape over the screws, not over the ground wires.

From Grounding Conductors size (PDFP:

For 15A - 30A, the sizes are the same as the hot & neutral for the same size circuits:

  • 15A - 14 AWG
  • 20A - 12 AWG
  • 30A - 10 AWG

Above 30A, you get to downsize:

  • 40A - 10 AWG
  • 50A - 10 AWG
  • 60A - 10 AWG
  • 100A - 8 AWG
  • 200A - 6 AWG
