Metallics PT4012V Ground Pigtail 12" #12 Solid Insulated Copper (Box 500)

The PT4012V is a 12 inch ground pigtail made from #12 solid insulated copper. Every piece in the box is the same length and gauge, so you pull one out, land it on the ground screw, and splice the other end into your grounding bundle without cutting and stripping wire on the ladder.

A #12 solid copper conductor is the common pigtail size for 20 amp branch circuits wired in 12 AWG, and it is also acceptable on 15 amp 14 AWG circuits since it is larger than the minimum required equipment grounding conductor there. The PT4012V is #12 solid, so it splices directly to the solid ground wires in standard NM cable without a reducing connector. For larger feeders, step up to a pigtail sized for that circuit instead.

They ship 500 pieces to a box. That is a bulk quantity aimed at rough-in and trim-out crews doing device boxes by the hundred, not a small counter pack. Packaging is a box, not a bag or reel.

The PT4012V is supplied as an insulated copper pigtail wire only, 12 inches of #12 solid. If your box or device requires a 10-32 green grounding screw, order that separately. Many metal boxes already have the tapped 10-32 hole for it.

Labor. On a multi-family or commercial rough-in with hundreds of device boxes, cutting and stripping a ground lead at every box adds up. A box of 500 pre-cut 12 inch #12 solid pigtails gives every box the same length lead, which keeps splices consistent for inspection and keeps scrap off the floor. The trade-off is that you are locked to 12 inches, so if you need longer leads for deep 4-11/16 boxes with extension rings, cut your own or spec a longer pigtail.

Insulated. The PT4012V is an insulated #12 solid copper pigtail, so it is the choice where your inspector or spec calls for a jacketed equipment grounding conductor rather than bare wire. If your job runs bare ground throughout, you want a bare copper pigtail instead.

Yes. It is a solid #12 conductor, which is the size most twist-on wire connectors and push-in style connectors are rated to accept, and solid wire is the easier of the two to land in a push-in port. Check the connector's own combination rating for how many #12 solid conductors it takes before you bundle four or five grounds under one nut.
