I cannot picture a situation where I'd ever have two different gauges of

secure,,,then as a final precaution, tape it all up
Just about all the lights in a house has 2 sizes of wire. Usually a 14
feeding the light and one much smaller that comes with the light.
If you have to use tape, you are doing something wrong.
I DO NOT have to use tape. The connection is just fine without it. I
do it as a precaution and many of the electricians take that same
precaution as well. Because I now triple check the integrity I use the
tape more as a precaution to prevent a short in the event a wire nut
cracked and the shell portion would fall off.
That said some people say that if one has a poor connection it would be
better to just let the wire fall out rather than be held in place by tape.
AFAIK there is no definitive answer
