Manufacturer's seem to recommend that electrical connections with wire
nuts
be wrapped with electrical tape to complete the job. But I have seen this
done in only a small handful of cases. What do y'all recommend?

Thanks guys for all your comments. Some good reasoning for both methods. I
guess the best is to follow the manufacturer's instructions. None of the
packages at Lowe's instruct to wrap in tape although I did see that on at
least one manufacturer's website.

Here's another question on making these connections. I have read that there
should be a good mechanical connection of the wires first, then twist the
wire nut onto the wires. ie: twist the wires together, then twist the wire
nut on. Those packages at Lowe's had instructions just to insert the
untwisted wires straight into the wire nut, then twist the wire nut. In
fact, this manufacturer's site says to do so
http://www.nelcoproducts.com/wire_nuts_d.html. So is it necessary to twist
the wires first? Maybe this defeats the design of the wire nut? I had an
awful time the other night connecting some light gage stranded fixture wires
to much heavier solid hard copper wires for a pendant light fixture; it was
virtually impossible to twist those together and get a good mechanical joint
before using the wire nuts.
