Dedicated Lines - Sub panel or no?


Hi folks,

In a few months time I will be moving to a new home, where a spare bedroom and an understanding wife will enable me to enjoy the luxury of a dedicated listening room.

The first thing that comes to mind is installing 4 dedicated 20A lines. The breaker panel is on the ground floor, the room is on the 3rd.

I'm wondering which is better:

-to run all four lines from the breaker box all the way to the wall outlets,

-or install a sub-panel (is that the right term?) in the room, and use a single, very heavy guage line from the breaker box to the subpanel, then run 4 short lengths of 10 or 12 gauge from the subpanel to the outlets.

Thanks in advance for your advice

Kind Regards
Mick

Hi Zargon,

That helps a great deal,thank you. With your kind permission, I would like to follow your schematics once I get started on renovating my new home.

By the way, your home, system and the view look fabulous.

Kind regards

Mick,

Thanks, I spent a year and a half getting my system to this point and have a long list of things I still want to accomplish.

Please do get your installation specifics reviewed by a local licensed electrician, as codes do vary.

Also, AGON member "jea48" is an expert in this area, and was very helpful in advising me on my iso configuration. I hope he doesn't mind me mentioning that to you.
We installed an Equi=tech wall panel next to our rooms. We then run 10 dedicated lines of JPS In-wall cable to each room and used Oyaide R-1 receptacles. From the Equi=tech, there are copper lines running to (2) 3/4" copper rods in the ground. We spent about $30k on our electrical system and it shows.
No electrical system is worth $30K.

I put in a 4KVA iso, a 125va iso, a subpanel, and 6 dedicated lines, and 6 Porter Ports for under $1K.

Here is one link of very very many to supply houses with steep discounts on iso tranformers. It is best to find one local to avoid shipping these heavy beasts.
