I finally have a 16sqmm (6AWG) dedicated line, and I thought why not add some proper copper plumbing for a shield…
I made it from separate 16sqmm wires, so that the L and N are tightly twisted together with a screwdriver, and the ground wire is loosely bound around that.
An incision was made to the ground wire to solder the ground end of the copper pipe, right next to the grounding bus.
I plan to not install a socket, but instead hardwire the ends of my power cords to the legs of the line.
A photo of your handiwork would be much appreciated.
Got the photos working now.
When I ran my 10AWG stranded for all my audio crap. It had to be put into Flexible Armoured Conduit (AC) because it was run along the walls and floor of our Garage. Inside were the usual 3 insulated conductors for L/N/GND. But the 12AWG Romex was the standard 12/2 wrapped in flexible AC conduit for all the computer crap & Plasma TV. Both are home run back to the breaker panel on their our dedicated 20A breakers.
The Copper you did is a nice touch. 6AWG…that’s hard core !
Yeah, I thought why not run 6AWG, I bought 20 meters for 190€. (So a three-legged line makes for 28,5€/m…) Had over half leftovers and constructed a ready-to-install twisted line for my friend as a Christmas present.
I am just “worried” that the solder layer applied to the ground incision point that extends only somewhat along the pipe’s edge is compromised compared to melting some all the way around its rim?
Actually of course, RF impedance would be okay with even a more point-like connection, but it should ideally be a smooth-surface, metal-to-metal connection. Welding the copper with some argon TIG would burn the house down 
With the 16sqmm shieded line straight from the panel, with gear’s power cords soldered straight to the ends of the line, I’ve noticed overall greater grunt and punch to the sound. More heft and perhaps clarity.
My modded Electrocompaniet is in the repair so can only say with a meager receiver but it’s a definitive change to the better.
