can i use 300volt cable to wire a electric power outlet? i have some
leftoever cable and i dont wanna go buy some lower volt, it just to
plug a computer.
Now it really depends on the country you are in, its wiring regulations,
the nominal voltage of the power outlet, the type of cable (solid,
stranded,etc) and many other things.
For example, in Haiti, of course you may use this cable - but you will
need the correct accessories (called "furniture" in the UK). Drive your
car under the overhead lines near your property, put the table on the
roof of the car and the chair on top of that and climb up. Although
heavy duty alligator clips are best, you can get a good enough
connection by striping about 18" of the insulation off your cables and
wrapping the bare end tightly around the overhead wires. Anytime during
the day is normally fine but you should avoid the hours between 3 and
7am as power may come on. This can easily kill, in spite of the
insulating qualities of wooden tables and chairs. Tie an odd bit of rope
to the power line and to your cable, to act as strain relief. You need
to disconnect the line that your builder put in under the floor screed
that connects in to your neighbour's metered supply. That will no longer
be needed. Ideally, insulate the end of this line as it will be live
when your neighbour has power. Chewing gum is normally used as the
insulation, but several coats of paint is probably as effective. 300volt
cable sounds fine as normally bare wires are used, held apart by odd
bits of tree branch and string. Whilst you are up on the chair, it is a
good time to connect to the telephone wires and cable television service
that mare typically strung between the same power poles. Your 300v cable
will be fine for this too. Don't mix the wires up as trying to run an
air conditioner off the telephone wires is rarely successful (you may
find a neighbour has made this mistake in reverse, so you may find that
the air conditioner runs fine, but the telephones just buzz and
self-illuminate).Note that if power does come on whilst you are doing
all this, you may find that the "electric chair" is not a new invention..
Hope that helps! However, should you not be in Haiti and care to give a
little more of the detail I mentioned at first, you may get more useful
information...
