New Subpanel?

I second the copper lugs and bus bars. But if you're going to spend the extra money, look into the Siemens Sentron panels and breakers. If you're familiar with the industry, then you probably heard that Siemens is preferred over Square D. Many union shops that construct panelboards from scratch use Siemens guts.

I agree with Lak in regards to the size of the transformer, 5KVA.

Note the 5KVA Xentek Extreme for $1595.00 used.

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

Can you please fill me in with the benefit of the isolation transformer.

With an isolation transformer like the Topaz or the Xentech Extreme:
>Low capacitance coupling between the primary to secondary windings of the transformer.
>Electrostatic shielding between the primary and secondary windings.
In a nutshell, all the crap, EMI noise, RFI, and anything else you can think of on your AC mains will not cross over to the secondary of the transformer. The secondary is isolated from the primary.

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.
