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.

No clue about electrical requirements in Singapore but check this out. Surge protection, regulation, isolation and breakers included.
