Dedicated line question

Sorry the question I
is focused purely on electrical draw. I’m aware of all the preferences around noise etc. this is just my lack of knowledge of electrical. I’m guessing if nothing else is ever drawing current on the other outlets and I’m supposed to have a dedicated line that from a pure power pull perspective it’s no different ?

Yes. If its on the same circuit as another item then it is not a dedicated line, is it? It's a shared line.

OP, you are thinking correctly.  In that sense, same draw as long as you don't plug anything else in.

What you are talking is not a dedicated line, which by definition is one breaker one wire one outlet. You can have multiple gangs in the outlet. But the minute you start stringing it to others it is no longer dedicated.

Party line. You want a crank with that?
