What wire to use instead of Romex

@jea48 

They are not on the same Leg, Line. One is on Leg, Line 1, and the other is on Leg, Line 2. He’s not an electrician. Keep looking. 

I suspected that every other spot on the s-shaped bus bar was the same leg since my 240 outlet runs off of two consecutive spots and yes, I have another estimate scheduled in about two weeks by someone I know to be a capable electrician. 

Why are you wanting to feed the two new dedicated branch circuits from the bottom panel? I would use the Top panel instead. There is one spare space available. 

Great idea to use a single pole tandem breaker. Placing it in the top panel also saves me a couple of feet of run.

Save the top left side for a Type 2 SPD

I’ve been thinking about how to address the risk of a surge. I’ll ask the electrician about installing one. I should definitely have some protection for my power amp.

As long as the TV and other things are not connected to the audio equipment with wire interconnects. 

The only thing running between them will be an optical cable from my TV to my DAC - complete electrical isolation.

Once again, your advice is invaluable!  Thanks!

I would also recommend moving the 1 pole 15 amp breaker over to the space on the left next to the 2 pole 100 amp breaker, that feeds the sub-panel in the condo. Install the 20 20 tandem breaker in the right hand space. 

Reason? It moves the Tandem breaker at least one space over away from the 2 pole 100 amp feeder breaker for condo sub-panel. Therein from the Electromagnetic fields surrounding the breaker caused by the load current running through it. The greater the load current the stronger the electromagnetic fields around it. 

(FYI, speaking of the single pole 15 amp circuit breaker. I don’t think that’s a Square D Homeline breaker. The lug the branch circuit wire terminates in does not look right. When you pick up the Homeline 20 20 Tandem breaker,  pick up a single pole 15 amp Homeline breaker.

One more thing. Have the electrician install two wall  outlet boxes. One for each dedicated branch circuit.  Do not install both branch circuits in a common 2 gang box...

What type of branch circuit wiring have you settled on having installed for the two dedicated branch circuits?
