Dedicated line problem

I had my house installed with one dedicated line running to my entertainment center when I built it. In the breaker box there is one circut dedicated for the entertainment center.

I have a full Isoclean setup $$$ running out of this line. When I turn on/off a ceiling fan/light I can hear a loud popping sound coming from my speakers. Should this happen or did the install go wrong?

What can I do to fix this problem if there is one?
IS the ceiling fan taped off the dedicated line?
The system is in the living room and I can go into the bedroom and turn on/off the ceiling fan and hear the noise through the speakers.
Hello Glory,
I had a similar situation in my home/system. I tried everything to get rid of it (drove me nuts), and finally determined a bad earth ground was the major culprit. I dug up the ground rod by the meter base, and found the thing in a very rusted condition, and the clamps attaching the ground wire had deteriated. I removed the ground clamp, vigorously power wire-brushed the area, used a new and better ground clamp, and then covered that section with automotive undercoating to preserve the connection.
It seems the probelem can appear also when extremely dry conditions occur, causing a less-than-perfect grounding. A good soaking with a sprinkler can help.

I don't know if this will help you, but it sure helped in my instance.
Good luck,
Understood that the system is in the living room. Understood that the ceiling fan is in the bedroom. What Apachefl is asking is 'are you sure that the circuit that powers the ceiling fan is NOT taken from (taped from) the living room circuit'?

Understood that you built the house. Do you have a relationship with the wiring installer? He could likely answer this question. If not, what I would do, first, is take down enough of the ceiling fan that I could temporarily install the 'broadcast end' of a circuit tester and then take the 'finder end' and go back to the service panel and find which of the breakers is feeding this circuit. There may be more sophisticated (easier to hook up) circuit testers, but this is the only type the I have used. This may answer this question.

In houses that have a 'production wiring job', it has been my experience that there are many 'shortcuts' that may be taken to make the job 'easier'. IF, and that may be a big if, the ceiling fan fan 'fed' from your dedicated circuit, what you are experiencing would certainly be a likely outcome.

The other thing that I would suggest from my experience (I completely re-wired our home and installed new service panels), is to carefully check and make sure that your ground system is clean, tight and well earthed with adequate ground rods coupled together.

How old is the house?

You might want to replace the wall switch. Spend at least $5 for a new spec grade switch. Good chance the existing switch is a cheapo 79 cent residential grade.

Here is something else you could try if the problem still exists after replacing the switch. You could add a resistor and a capacitor in series, paralleled across the switch contacts.

The best way to dedicate a circuit(s) for a home system would be a seperate sub panel with all the dedicated outlets connected to it. No other lighting fans or dishwasers just outlets. Any problems you know where the source is
lol I have the exact same problem. The electrician thought I was batshit out of my mind for asking for a dedicated line to the den and the bedroom and I am wondering if he just lied to me and didn't do it.

Simple way to check.

The electrician should have identified the breaker/s for the dedicated branch circuits on the index label on the inside of electrical panel cover door.
Turn off the breaker/s and check your home for any other de-energized
receptacle outlets or lights.
If your ceiling fan is wired to a switch that controls the speed of the fan, you might want to try replacing that switch with a regular single pole switch that doesn't have a speed control. I had the same problem that was corrected with a 29 cent single pole switch.
No speed control for the fan off the wall.
