no other wiring close to cable ..hi AK,
Will the 15 mtr cables path be exposed to high external electrical noise/fields.?
ie: laid alongside other existing wiring .?
Will it be a twisted pair or screened cable.?
Indoors or Outdoors.
what is the best twisted or screened ?hi,
A twisted cable is two conductors which are twisted at approx 5 turns per inch, along their full length.
This helps to reduce the electrical noise picked up by the cable from external electrical sources.
Screened cable can be a single conductor with an overall braided copper screen along it full length.
or twin conductors with braided screening.
You should consider if the wiring is out doors, the possibility of a lightning strike close by.
thanks alot erichi,
I would use twisted pairs, look at this diagram.
It will give some protection against over voltages and electrical noise.
It is almost impossible to protect against a direct strike, the keep the wiring out of trees etc.
