What cost are you anticipating?
Dedicated Line Advise
I currently have a 20 amp dedicated line run to my small HiFi rig; amp, preamp, CDP, TT, power conditioning. I wish to add a second line using the same electrician who has worked on my house. It looks like he used 12 gauge Romex last time.
What are the key facts that I should know in case he is not familiar with doing wiring for audio systems?
I'm talking about the installation at the breaker box, e.g., keeping proper phase and preventing a ground-loop between the 2 circuits.

ptss, The cost of installing a dedicated 20amp line plus grounded outlet was $200 back in 2010. But now, it will be more complicated since I'll need to reconfigure the box; moving high-current appliances away from the audio lines. I don't know the hourly rate for labor to do that. And I'll be adding Porter Ports this time. |
lowrider57; moving hot leads from one phase to another in the panel takes no time at all for an electrician. Adding a new box takes a little more work. But what you described is really not complicated. You could actually do this yourself if you knew how. On my house it is simple. I would go outside to my meter panel. There is a large circuit breaker for my house. Yes it is that old. I will trip off that circuit breaker, de-energizing the house feed from the meter. (I actually don't have to do this, but it is safer), Then I would go into the house to the breaker panel in my house. I would locate the breaker that feeds the line described, then remove the breaker, take the lead from that breaker feed and move it to the other hot phase in the panel. reconnect the circuit breaker, turn on the main breaker and you are done. If you are doing this yourself, just take a volt meter with you and measure that the voltage is turned off before proceeding. There are two hot leads coming into your home. An A and B phase and a neutral. A is on one side of the panel and B is on the other. They both measure 120VAC with respect to the neutral. They are out of phase with each other. If you open your breaker panel, you will actually see the two phase wires connected to the breaker bus bars on either side. You will see the neutral also and a ground (which is your house ground). If you are not comfortable doing this, an electrician shouldn't charge more that an hour's labor (that is very conservative) to do this. enjoy |
