[Elecraft] [OT] NEC wire size requirements

[Clay Autery]

You are correct... it is new construction add-on to existing...

FYI, when using twisted-pair, each pair essentially functions as 4
parallel wires for cross-section...  So I had to upsize to 1" RWS FMC to
accomodate 2 x 6AWG twisted pairs and not violate the 40% fill limit.

Conduit is NOT required in my locale.  It is being used for shielding
only... although it is UL Listed and installed per code.
