Strip to length recommended per wire nut instructions and stay within
the numbers for which the size of nut is approved (also on the box). If
that's close to upper limit I'll go to next larger size.
Generally, strip the stranded longer than the solid so have adequate
length as they wrap.
It should work fine. Sometimes stranded conductors will start to twist
away when I start to screw on a wire nut, making a less secure
connection. If the stranded conductors are bundled with solid
conductors, all straight, the solid conductors may keep the stranded
ones from twisting too soon.
There's a big difference in wire nuts. The first twist-on connectors
contained no metal. Threaded ceramic thimbles are still used. The
first ones called wire nuts had no insulation. They were springs that
would expand around the conductors as they were screwed on.
I prefer the kind where the spring has plenty of room to expand. The
connection feels very secure, and one size nut is approved for a wide
range of bundle sizes. The box should tell you if a wire nut is
approved for what you want to do.
Is antiox paste approved for copper? There are special wire nuts
approved for damp or wet locations.
I have a box of Ideal 71B, a box of Buchanan B2-1, and a box of GB
10-086. All say to hold the conductors together without twisting. Two
combine solid with stranded conductors, two say the ends of the stranded
should be slightly ahead of the solids. The Buchanans say this is
necessary only with 16-gage or smaller stranded conductors.
Holding untwisted conductors together to put on a wire nut can be
tricky, but I like the way a wire nut feels as it screws down on
conductors that haven't been pretwisted.
