Your One Bullet Point Solution; Electrical Upgrade
THOUGHTS in regard to two options electrician is offering? Both 200A Both will have some form of surge protection at panel Eaton CH Panel with space for an Eaton surge protection -The Eaton panel has uses silver plated copper bus bar connection -Breakers seem to be mounted directly onto neutral Square D with QO breakers -The Square D has a tin plated copper bus bar -breakers seem to be wired in My electrician plans on replacing the ground bars with copper. Again, if there are noise problems I will probably add an isolation transformer and sub-panel. QUESTION: So a load center can have more than one surge protection device? i.e. covering entire panel, and additional covering the circuits for the HT/audio room? The Siemens unit recommended by drlisz seems to do both entire panel and two circuits. Is that the same case with others, like the Eaton panel surge protector? |
TODAY is panel install day! It took longer than I wanted to coordinate the electrician and city inspector, as well as power co. to handle the cut over. Oh, well. This afternoon is the inspection, and tomorrow is the cut over! This should be fascinating to see if, subjectively, there is any difference in the system's sound. Frankly, in the long run, it doesn't matter so much, as it is one of dozens of ways to influence the sound quality, and I will keep finding more of them. You work with what you have in that regard, and build from there. I just pray it's not noisy power lines... If so, I'll have to consider adding an isolation transformer. I'm not going to put up with noisy power. Power cords should sound even better! ;) |
“The main advantage of a dedicated line is not the ability to provide more current. Our systems do not require anywhere near even a 15A draw let alone 20A. What we want is clean.“ For not-so-efficient systems that require lots of current, you could see a few volts of drop in longer lines during dynamic peaks. How would this affect the performance of an amplifier? Would it be better to size the line as large as reasonably possible to keep the voltage as close to 120V at all times? |
mkgus For not-so-efficient systems that require lots of current, you could see a few volts of drop in longer lines during dynamic peaks.Quite so! How would this affect the performance of an amplifier? Would it be better to size the line as large as reasonably possible to keep the voltage as close to 120V at all times?Yes. Derating the wire is accepted practice. NEC specifies only the minimum standards for electrical safety and performance. |
