Metallics MWNWR1810 – Frequently Asked Questions
1) Can I use the Metallics MWNWR1810 connector on aluminum wire?
The MWNWR1810 is a standard twist-on winged connector for the 18 to 10 AWG range. Aluminum and copper-to-aluminum splices call for a connector specifically listed for that use, so if you are working an aluminum branch circuit, source a connector marked for aluminum rather than using this one.
2) What is the difference between a winged wire connector and a plain twist-on wire nut?
A winged connector like the Metallics MWNWR1810 has molded side wings that give you leverage to twist it down by hand, which matters when you are making up a lot of splices in a panel or a box overhead. A plain twist-on has no wings and is usually driven with pliers or a nut driver. Electrically they do the same job; the wings are about install speed and hand fatigue.
3) What does the red color mean on the Metallics MWNWR1810 wire connector?
Color codes the size range on twist-on connectors, and red is the larger of the common residential sizes. On the MWNWR1810 that red body corresponds to the 18 to 10 AWG range. If you are stocking a box for a job, the color is what your crew will grab by sight, so keeping the reds for heavier splices and smaller colors for lighter ones keeps the make-up consistent.
