Conduit

It is best practice to run invididual THHN wires inside conduit. Thus it appears that for part degeneracy, one may strip THHN wires from Romex [1], and run them inside conduit. This can apply to hardwired plugs if one doesn't have multistrand THHN wire - where stiff wire is ok if conduit length is short, such as a hardwire whip. This could free one from having to source 14, 12, 10, and 6 ga multistrand wires - and enabpling one to make hardwire whips from the same Romex used in other wiring. This makes a good case for electrical part degeneracy with the Seed Eco-Home.
