Metallics PT40J – Frequently Asked Questions
1) What wire size and length is the Metallics PT40J ground pigtail?
The PT40J is a 7 inch ground pigtail made from #12 solid insulated copper with green insulation, terminated with a zinc-plated steel ground screw. Part number is PT40J.
2) Will a #12 ground pigtail work for bonding a metal box on a 20 amp circuit?
Yes. The PT40J uses #12 solid copper, which is the same size as the branch circuit conductors on a typical 20 amp #12 run, so it bonds a metal outlet or switch box into the equipment ground without undersizing the jumper. The green insulation identifies it as the grounding conductor.
3) Does the Metallics PT40J come with the ground screw already attached?
It does. The pigtail is supplied with a zinc-plated steel ground screw on the end, so you thread it straight into the tapped 10-32 ground hole in the box and splice the free end into the ground wires. No separate screw to buy.
4) How many ground pigtails come in a jar of Metallics PT40J?
They ship 100 to a jar. That is the pack type for the PT40J, so a single order quantity gets an electrician enough pigtails for a full rough-in or panel job rather than a handful.
5) Should I use a ground pigtail or a separate green ground screw and loose wire?
A pigtail like the PT40J saves a step: the green #12 conductor is already attached to the screw, so there is one part to grab and one screw to drive instead of cutting a jumper and fishing a loose screw out of the bottom of a pouch. Loose green screws make sense when you want to set the jumper length yourself; the pigtail is fixed at 7 inches, which is enough to reach a wire nut in a standard device box.
6) Is 7 inches of pigtail long enough to reach the ground splice in a standard box?
For a single-gang metal device box, 7 inches gives you enough tail to come off the screw at the back of the box and reach a wire nut with the incoming grounds. In a deep multi-gang box or a 4-11/16 square with a lot of conductors you may want to plan the splice closer to the screw, since the length is fixed at 7 inches.
7) Why is the ground screw on the PT40J zinc plated steel instead of copper?
The screw is zinc-plated steel for thread strength and corrosion resistance in the tapped hole of a steel box, while the conductor itself is solid copper. The copper carries the fault current; the plated steel screw holds the mechanical connection to the enclosure.
