Putting in a dedicated power line. 2 receptacles ok?

in your breaker box you have two sides or rows of breakers. By having them on opposite sides the ground is then not interacting with each other which reduces noise.

I think you got some bad advice if your video is connected to the audio system.

@jea48 
I think theo may be misquoting the electrician. I believe he has a line for his video setup on one leg, audio setup is wired to the other leg.

That's why I said ground and neutral is common. The video line and audio line use the same ground. There is no separate ground for each line.

Yes my terminology was incorrect. And I do have 2 circuits on different legs, sides , whatever it is called. And it has worked well for a number of years. After all these years I can’t quote my electrician verbatim. But as mentioned, maybe the simplest way o explain is Audio is a 20 amp circuit on the left side of the breaker box and video is 20 amp on the right side of the box.

sorry for any confusion

Told ya, clear as mud.. LOL

As long as it works. Who the heck cares?

Both Line 1 (L1) and Line 2 (L2) alternate down each side of the panel. That’s how 240V load(s) can be fed from a 2 pole breaker.
Example:

Left side... Right Side
L1 .................. L1
L2 .................. L2
L1 .................. L1
L2 .................. L2


With that said the electrician may very well have fed the two 120V branch circuits from both Line 1 and Line 2. Easy way to check is with a multimeter. If both the circuits are fed from opposite Lines, legs, measuring from the hot contact (smaller slot) of a receptacle connected to one of the branch circuits to the hot contact of a receptacle connected to the other branch circuit you will measure 240V nominal. If both circuits are fed from the same Line,leg, you will measure 0 nominal volts.

You say an electrician installed the two circuits a number of years ago. Do you remember if the electrician installed Romex? Did he install two Romex cables or maybe only one?

IF only one Romex cable he installed a 120/240V 3 wire multiwire branch circuit. If that is the case you have two separate 120V circuits that share a common neutral conductor. The Romex cable will have 3 insulated conductors + a bare equipment grounding conductor.

If it is a multiwire branch circuit both hot separate circuit conductors must be fed from breakers fed from L1 and L2.

No worries, that's how I interpreted your post. And yes, as long as it works.
