So the only thing of real value here is a 10 gauge wire to ensure there's plenty of unimpeded impulse power for all the frequency demands. Even if you run a hair dryer it's still gonna spread throughout the panel and contaminate component. Maybe a sub panel would be a lot better. Or maybe buying a new dog as long as he doesn't bark all the time.
Single plug dedicated circuit?
I guess if you truly want to do a dedicated circuit wouldn't you have to be allowed to only plug-in one device. If you plug two items into the outlet isn't one item going to contaminate the other item with noise from the first item?
So a multi branch circuit would be sharing 4 items.
I guess it gets down to sharing and Best to share with one but tolerable and acceptable to share with 4 components plugged into the quad outlet?
So how many people are only using one component per circuit breaker which is the truly finest way to receive a pure signal, at least if you ignore what occurred before the current reached the circuit breaker.
