I do have to admitt to a special case for me to tape a wire nut. Wiring
up motors where there is a lot of viberation I sometimes did tape up the
wire nuts. Two reasons. They may viberrate losses, but mainly because
being in close contact with the metal junction box it may take longer
for it to wear through. Tha this the only time I ever taped any in
thousands I installed when working.

That is another case where 2 different sizes of wires may be used. Often
the motor wires would be smaller than the feeder wires on those motors.

Just lay the wires next to each other and screw the nut on, then give it
a good tug.


On motors I generally like the vibration proof MARR type connectors
with the setscrews because you can only twist and untwist the internal
wires so many times until they get too short. The set-screw type can
be reconnected MANY times without damaging the wire. The 2SHD and 2SHP
type
