New Subpanel?

The distance from main panel is around 75 feet but when you wire around all the obstacle is around 110 feet. There is not enough room for more circuit breakers in the main. I didn't know that is best to use the same LINE (L1)or for all audio equipments.

Thanks

Is interesting so you suggesting an isolation transformer. So the output power would be pure so I don't need to worry about power condition which in turn save me some money on the power condition or power cords which it will pay for the isolation transfer. What is the type of isolation transformer you suggesting. I do have room for the transformer.

thanks

Lak can you provide the link to Xantech Extreme transformer. I will go with the conduit route. Please add more suggestions.

Thanks

I used to work for electrical company. So I know all the basic of installing the subpanel. The subpanel will be 120/240 with 60 amp feeds and 4 dedicated circuit to the room with #10 wire with hubbel hospital grade plug. I am still debating Romex vs conduit. Is there any benefit to use conduit? Even thought I calculated all the load to be around 2300 watts which is a 20 amp circuit would do. As for the panel I would take your recommendation of the Square D Panel I prefer the bolt breaker which cost a little more :)

My audio systems list:

1. Mcintosh MC2000 Amp (2)
2. Mcintosh C2200 Preamp
3. Mcintosh MCD1000 Transport
4. Mcintosh MDA1000 DAC
5. B&W 802D Speakers

In the future I would add a plasma or LCD TV and make it into home theater for my other half.


Thanks again

Thank for the link to transformer. I know most of the basic of the installation of the panel and line. Can you please fill me with the benefit of the isolation transformer.

Thanks

Rocky

Thanks Jea,

I might start with the subpanel first and leave enough main feeder wires for future upgrade if I decide to add the isolation transformer later on when save enough dought.
So in theory is the transformer will keep the secondary voltage constant and clean. No power conditioner is needed for the audio systems.

I always believe in BIGGER gauge wire and conduit. I usually used one size bigger. The conduit is 1-1/4" and the wire size is #4 copper wire since I already have one big roll in the basement. I think is a 500 feet roll so it might be enough for the ground wire :). I will use the PS-1000 for the digital end.

Thanks again for all your help to make this project come true.

Do I need any surge protector if I install the isolation transformer?
