Metallics MWNWGR1410 – Frequently Asked Questions
1) What wire sizes does the Metallics MWNWGR1410 grounding wire connector take?
The MWNWGR1410 is a green winged wire connector made for grounding splices in the 14 to 10 AWG range, so it covers the common #14, #12 and #10 copper branch-circuit ground conductors you find in residential and light commercial boxes.
2) Why is this wire nut green instead of the usual red or blue?
Green is the color convention for equipment grounding conductors, and the MWNWGR1410 is a green connector made specifically for ground splices. Using it on grounds keeps the box readable for the next electrician or inspector, who can tell at a glance which splice is the ground without pulling conductors apart.
3) Can I use this green wire connector on aluminum ground wire?
The MWNWGR1410 is specified for 14 to 10 AWG grounding conductors in a twist-on splice; for aluminum or aluminum-to-copper connections you want a connector rated for that combination rather than a standard twist-on ground nut. For copper grounds in that size range it is the right part.
4) Does the Metallics MWNWGR1410 need a tool to install?
No tool needed. It is a winged connector, so the two wings give you enough purchase to twist it down on the conductors by hand, which is why electricians favor winged nuts for deep boxes and overhead work where a plier swing is awkward.
5) How many ground wires can the MWNWGR1410 hold?
Capacity on a twist-on connector is set by total conductor fill, not a fixed wire count, and the MWNWGR1410 is built for combinations within the 14 to 10 AWG grounding range. A typical use is two or three #12 or #14 grounds pigtailed together in a device box. Keep the conductors bottomed out in the connector so no bare copper shows below the skirt.
6) Is there only one version of the Metallics MWNWGR1410 to order?
One configuration, model MWNWGR1410, the green 14 to 10 AWG winged ground connector. There is no size or color choice to specify on it, so an MRO or multi-family buyer standardizing ground splices across a facility is ordering a single part number.
