Dedicated 20 amp circuit - Electrician laughed!

LOL.....   after so many miles of garbage quality transmission lines and grunge being put into the lines you think cleaning up the last few feet is going to make a difference?  REALLY?

Luckily. I have an electrical background as it was my major at my vocational high school I attended, and so I have no fear with most DIY electrical work. What prompted me to install a dedicated 20 amp circuit for my system was the lousy 15 amp existing circuit available in my living room. This circuit ran everything in the room of course, the tv, fans, plugged in table lamps, etc....everytime I’d play my system rather loud, I’d notice the lights dimming noticeably while plugged into the existing 15 amp circuit. This to me was annoying and unacceptable. So I gathered all necessary supplies (12 gauge romex, a handi-box, audioquest NRG copper receptacle, and a new 20 amp circuit breaker) and I got to work! It took me about 4 hours time to complete (about a 40 foot run, due to proximity of panel to room), but well worth the effort and the cost savings of doing it myself. I can say that there are no more dimming lights, and I can honestly say that I noticed that the system seems quieter, a darker back ground so to speak. I added to this by utilizing an audioquest niagara 1200 power conditioner as well as AQ thunder power cord for amp, and the NRG X-3 cords for sources. To me it was all a worthy cause, and actually a fun project. One thing to add about the AQ NRG receptacle is that it grips the power cord prong like a gorilla...you need to be Hercules to remove the plug now...unlike the cheap ass receptacles that are loose....

" Pretty much. Every service requires a grounding electrode. You can add a second one but it must be connected to the first one by a wire. At the end of the day, within a single electrical service, all of your ground wires and all of your neutrals are connected to the same ground at the service"

Thank you.  I have long thought it a little crazy to have a separate ground on the dedicated line.

As a person who worked his way through college by working out of IBEW 175, and whose Dad was it's one time president, I must state that anyone who runs a separate ground rod from his dedicated circuit is asking for a charge of negligent homicide to be added to his resume.  This is dangerous, totally against all electrical codes, and totally ignorant of how A/C electricity works.  Ask you local building inspector for a permit for this, and he will visit your property regularly, forever.

I use my clothes washer circuit.  It allows the amps to charge up without the ebbs of other power draining sources.  Of course, now that the electronics have taken over my laundry room, I can watch the garage lights on the circuit with the washer dim with each reversal of the agitator.
