Exactly. That's my question.
Time for dedicated outlets!
I would like some advice on what exactly to tell my electrician to be sure I get what I need. Is just saying that I want two separate dedicated lines to the listening room sufficient or are there other key fraises that should be included in my description of the work I would like done?

I misspoke (wrote)? 10-3 would be three conductor with ground. 10-2 is sufficient. Please check this out from Vince Galbo @ MSB..... http://www.msbtechnology.com/faq/how-to-wire-your-house-for-good-power/ |
@cerberus79, Run a 12/3 romex that is a neutral with two lines and a ground. This will give you two dedicated 20 amp cicuits with one run.No, that would be 2 separate 120V circuits. A 3 wire 120/240V multiwire branch circuit. Two separate 120V circuits with a shared/common neutral conductor. A 120V dedicated branch circuit is a branch circuit with a dedicated, Hot conductor Neutral conductor Equipment grounding conductor. A true dedicated circuit does not share a raceway, conduct, or cable assembly, with any other circuits. Multiwire branch circuits are not recommended for feeding audio equipment. Especially where audio equipment is connected together by signal wire interconnects. It also should be mentioned the 2 circuits of the 120/240V 3 wire multiwire branch circuit must be connected to a 2 pole breaker, per NEC. Only the imbalanced load, of a 3 wire multiwire branch circuit will return on the shared neutral conductor back to the source, the electrical panel. The balanced load of the 3 wire circuit is in series with the two hot ungrounded conductors. Example: If the connected load on L1 to neutral is 5 amps and the connected load on L2 to neutral is 5 amps, zero amps will return on the neutral conductor of the branch circuit back to the source. The two loads are in series with one another, essentially being fed by 240V. So say Digital equipment is fed from one of the separate 120V circuit outlets and the analog is fed from the other separate 120V circuit outlet, Only the imbalanced load of the digital equipment and analog equipment will return on the neutral conductor. The balanced 120V loads, of the two connected loads, will be in series with one another. Do you really want the digital hash going back out on the power cord/s of the digital equipment coupled to the power transformer/s of the analog equipment? Here is a very good video on how a multiwire branch circuit works. https://www.youtube.com/watch?v=eVamt9IdQd8 . |
Jea48, The NEC does not clearly define that and it is left as a design perrogative. It is understood that a dedicated circuit is one where only one appliance will use that circuit. A neutral can be shared but only one appliance per breaker. Some elect to run a neutral for each as a design choice. In either case the neutral is run back to the panel and attached to the neutral bar where all the other neutrals are. |
