I'm going to add my last dedicated line, this for digital components, and was thinking of running the romex from the service panel, inside of 3/4" copper pipe instead of the usual metal or plastic coated metal conduit. Anyone try this or have any suggestions to this end?

Be real careful. There is no standard way to protect the Romex from chaffing where the wire enters and exits. Why you might think, how could that possibly wear through the insulation? I have seen it happen. Years of tiny vibrations and movements created a short circuit electrocution Hazzard. I was surprised and lucky. Guess the code is there for a good reason!
He would need to use a copper pipe to male thread adapter. See Link below.If he used any boxes they cannot be galvanized steel. Same for the lock nut used to mechanically/electrically connect the fitting to the box. Any copper fittings would need to be soldered to the copper pipe for conductivity continuity of the conduit system.

jea48 and jk thank you for your advice and the link, much appreciated.
believe that unclestu talked 'something' similar to your inquiry about a couple of years ago...doesn't hurt to check the archives.
Stick w/ EMT-
It will serve all the goals you have stated about the copper and meet code.
the copper won't.
Happy Listening
Will do and thanks, the use of copper pipe was just a thought.
Steel EMT will provide shielding as well as copper tube at much less expense. Also fittings and connectors are available.
No. Probably worse

and include examples to show your thesis.
Copper, pipe in this case, is non-magnetic and a great/good conductor of electricity, minus the oxidation factor, I could fill the pipe with sand or something else, cotton rope for example, to kill the accompanying vibration generated by the 50/60 hz cycle generation and its a great rf shield, though I have had instances where the reflection back at/to the source has had deleterious effects on the overall performance and had to be removed or "dampened". My concern is that it could also act as an antenna of sorts, though earth grounding it, the copper pipe, should resolve at least some, if not all, of this. It also would act as a shield to the surrounding equipment and keep whatever insulation bleed-through from the ac cabling, read emi, no matter how small and seemingly insignificant, from effecting the performance of the components in close proximity to the run.
Makes sense to me, your thoughts?
95% of what you just rambled through could be achieved at less expense using EMT.

Thanks for your input. Why the attitude?
