Replace panel or add subpanel?


Gentlefolks,I am in discussions with a builder for finishing the basement, including a dedicated listening room. For the most part, he seems to get audiophile requirements (e.g, running a dedicated line). He proposes installing a subpanel and running everything for the room off that. But if there are problems with the old panel, won’t I create a problem of garbage-in-garbage-out? Wouldn’t I be better off replacing the old panel with a new panel? Much thanks,

I think your electrician is giving you the more economic solution with a sub panel vs. a complete replacement.

If you already want to replace the main panel anyway, say to clean up code violations and/or breakers being used for more than 1 run, then sure.

OTOH, if your listening room was 60' away, and you wanted to run 4 or more independent circuits then a sub panel would be a really good idea.

Also, never underestimate what you may discover and have to pay for with a complete replacement. :-)

The sub panel is a great idea for convenience’s sake. You can run a 60 Amp circuit with 1 cable, and then have short runs to the room, giving you a number of dedicated outlets. If your listening room is far from the main panel, this is going to be a great, flexible solution, and may be cheaper than attempting to run multiple lines. Also, all your grounds will end at the same single reference point int he subpanel.

It may also be a good idea to update your panel. :)

And, if you want to go totally nuts, you can even put balanced, isolated power before the subpanel. :)

Best,
