Question from the field:

Quote
We are installing Cat 5E cable to connect an emergency speaker system for Lehman Brothers. They are having us run this four pair conductor around these 40,000
sq. ft floors. They are having us use three pairs for power. This is supposed to adjust the voltage drop, one pair for voice.

I know its low voltage but having these pairs twisted in parallel, just don't sit easy with me.

Am I wrong?
