Question Stranded wire to solid wire connection?

Great forum, tons of information. Thanks.
Looked around for a while and haven't found anyone expounding on an acceptible/correct way to connect stranded wire to solid wire? (light guage, 18-14).

I know that you are not supposed to use wire nuts(although I have, and haven't had any problems). I am sure that if you weren't careful, it would be very easy to cut through some of the strands, thus weakening the connection and possibly creating a fire hazard.

Would it be acceptible to tin or coat the copper strands with solder prior to using a wire nut? Or, better to use crimp connector to convert/connect different wire types? Or. any special connectors designed to specifically for this purpose?

Any info will be greatly appreciated

I use wire nuts. What makes you think they are not acceptable? Use the proper size and they work fine.

All I've used is wire nuts.

But, I thought that I had read somewhere(probably on a fixture box) that the stranded wires should not be connected with wire nuts. So, I thought I would try to find out if there were some code accepted way that it had to be done.

I guess I will just keep on using wire nuts until I hear differently.

Wire nuts are acceptable if they are listed for stranded wire. If you look at the package of wirenuts, or the manufacturer datasheet, it will tell you the different combinations of wire which are acceptable. In some cases you will have _different_ allowed wire combinations for stranded wire.

I've had no problems joining small stranded fixture wires to 12 and 14 ga solid wire using wirenuts.
