Subject: Re: [motm] OT: clean power in basement studio

Thanks for all the helpful info - this list is great! :)

So far I understand the following: assuming I have separate ckts for
the studio, it doesn't matter which "phase" they are on (which side of
the panel). So far so good.

Now this is a little more complicated.

Ok, I have one twisted copper ground wire from my panel to the city
side of my water line, and another similar copper wire (from the panel)
connected to a rod buried in the ground just under the service
entrance. Does this count as one common ground point?

And the thing to do here would be to disconnect the neutral ground and
connect signal ground to earth ground, yes?

And as for MOVs - those are the cheap surge protection devices in yer
typical plug strip? What exactly is the problem with these? My whole
studio is infested with them! :(

Thanks again,
