Re: new home wiring questions

Ethernet and speaker level signals are generally not affected by A/C
interference. Ethernet runs at too high of a frequency and is balanced
(common mode rejection if you want to look it up on Google). The A/C
induction for speaker level signals will be impossible to hear, there just
isn't enough signal leakage to drive the speaker. (But, this is not true for
line level or mic level audio signals where you might get interference. Or
you might get interference in your audio components or from ground loops.
You should try to run lighting on a separate power phase.).

Also, if you run other signals on your Cat6 (particularly unbalanced
signals) you may have some interference in which case you should try to keep
the cable 12 inches away from A/C and if the cables have to cross they
should do so perpendicular to each other. If you use conduit, you should put
the A/C in the conduit.
