Metallics MWNR1810 – Frequently Asked Questions
1) What wire sizes does the Metallics MWNR1810 red wire connector take?
The MWNR1810 is rated for 18 through 10 AWG conductors, which covers the usual range from low-voltage control and fixture wire up through 10 AWG branch circuit conductors. Red is the color code Metallics uses for this size range, so if you are matching what is already in a junction box, a red twist-on nut generally indicates this larger wire range rather than the smaller blue or orange sizes.
2) Can I use a red 18-10 wire nut to splice 12 AWG and 14 AWG conductors together in the same connection?
Yes. The Metallics MWNR1810 accepts any combination within the 18 to 10 AWG range, so mixed 12 and 14 AWG splices are within its rating. Keep the total conductor count within what the nut will physically seat on, and strip to a consistent length so all strands twist up into the spring.
3) Is the red Metallics wire connector the right size for two 10 AWG conductors, or do I need a larger nut?
10 AWG is the top of the MWNR1810's range, so a two-wire 10 AWG splice is at the upper end of what this red connector is built for. For heavier combinations, more than a couple of 10 AWG conductors, or anything above 10 AWG, step up to a larger connector instead of forcing this one.
4) What is the Metallics part number for the red 18-10 twist-on wire connector?
Order it as Metallics MWNR1810. That is the manufacturer part number for the red 18 to 10 AWG twist-on wire connector, and it is the number to quote when a drawing or BOM calls out a red wire nut in that size range.
