Dedicated Circuit with Two Prong Plug?

Thanks Stanwal. My electrical knowledge is limited, but from other threads on the subject, I've gathered that most folks have either a single dedicated line plus conditioner, or multiple dedicted lines with no conditioner...lots of in-between too.

There seems to be an issue regarding ground potential that can produce hum with multiple lines. For example, the different circuits using different guage wire, recepatacle/breaker ratings, and/or grounding techniques.

So, I'm wiring three lines with 20 amp breakers, 20 amp receptacles, and 10 guage wire. I'll then decide whether or not to use my conditioner somewhere. Anyway, that still leaves me wondering if my two prong tuner upsets something?

I don't see any problem at all using a 2-prong device with your conditioner and other devices that have 3-prongs. As Stan indicated there may be better results in terms of hum and noise using one orientation rather than the other.

You can assess that either by trial and error, or with a polarity direction finder as he mentioned, or, if you have a voltmeter, by measuring the ac voltage between the tuner chassis and ac neutral (the wider of the two parallel prongs on the outlets of the conditioner). Whichever orientation gives the lowest reading will ordinarily be best. That reading MUST be taken, though, with no interconnect cables connected from the tuner to any other components, just with its ac power cord connected. Otherwise the reading will be meaningless.

As you've probably read, the key to avoiding the problems you mentioned with ground potential differences between multiple dedicated lines, if you are using single-ended interconnects, is to use interconnects which are both high quality (specifically with respect to having low shield resistance), and as short as possible. Components with balanced interfaces are much less susceptible to that kind of problem.

Thanks Al...good info.

Kennythekey: If you are running more than one dedicated line make sure that they are on the same leg in the breaker box, otherwise you may have different ground levels. Don

Thanks Don. Same leg?...as in the same line into the panel box?
