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.

Thus, conduit-clad whips in the OSE case can utilizer LFMC to keep redundancy for both exterior, interior, and appliance wiring.

1. Heat pump: feed with 10 Romex, can do 10 ga in LFNC for whip
2. PV: THHN multistrand + LFMC required, as wiring inside walls must be metallic.
3. On-Demand water heater - hard wire with 6 ga Romex directly through wall with heater-as-junction box
4. Minitank heater - 20A hard wire (because plugs are special) into regular box, wire coming out directly from wall into minitank-as-junction box
5. Dishwasher - use 15A plug, which is a common part.
