Dedicated Circuit

So from what I’m told by the electrician because I have 100amp service there is no way to separate the “phase”. So presently I have a dedicated 20amp circuit for my Krell Digital Vanguard. Because it’s a duplex plug I could just plug my Furman PC into that other plug for my sources. Just wondered if there was any benefit to either separated or all on that 20amp circuit?

Hi jea48
electrician said that with 100amp service everything on the electrical panel is on the same “phase”. While I have a dedicated circuit it still is subject to influences of the rest of the house.
I don’t know if this is accurate or true. Need to do some research on this.

@ jea48,
Thanks very much, I really appreciate the detailed response and learned a great deal. So when my electrician installed the 20amp circuit breaker it is in fact right below two other 20amp breakers for the air conditioning units 20amp breakers,(two of them).
So should this be moved to the other leg or down further with separation between them? I think when these guys work they like to keep things all together nice and neat.

jea48,
so I just looked at the breaker panel again. The dedicated circuit is right below my mini-split air conditioning breakers which are dual 30amp. Haven’t used the air yet this year (chilly New England) so not sure If it will generate any noise.
If it does, bummer, have to get electrician back here. Tried to do my homework but should have talked to you first :-(
thanks for your expertise!
