I want to put a Cat5E low volatage phone line in a box about 2 inches or so
from a high
voltage duplex plug box in a kitchen. Is there a problem with this? Is
there a certain distance that they have to be separated?

Also, I want to join two pieces of Cat5E for the purposes of voice, not
data. Which type of silicone filled splice connectors works best. I have
tried some before that just do not work very well. I would like to butt
splice all eight conductors. Do I do 1 conductor from each side of the
splice per connector?

That will be fine. If the high and low voltage cables are parallel for more
than a few feet keep them separated by a foot for 110VAC and 2 feet for
220VAC. They can run closer for a few feet to go up inside a wall to the
junction boxes with no ill effect.

If the lines will only be used for voice, any gel-filled crimp connector
will work. If the splice is indoors you can even use unfilled crimps.
However, the preferred method is to use a 110 or 66 style punch down block.

Just match them up color for color and all will be well.

Do you realize that "high voltage" is considered over 69kv? "Medium voltage"
is anything over 1k to 69kv.
Most people use the term "line voltage" to describe 120-240v systems.

If your using Cat 5 for voice then use any connector you like. I prefer to
use crimp connections but that is just me. You will get satisfactory
performance with wirenuts if you want to use them.
