[RE-wrenches] "PV wire"

[Marco Mangelsdorf]

Is double insulated (e.g., Falcon-brand wire) considered "PV wire"?   That
is, the kind of conductor needed for ungrounded (DC) PV systems?  Any other
non-double insulated wire type considered "PV wire"?

 

And we seem to have a consensus that once the PV wire (for an ungrounded
circuit) reaches a junction box and the circuit wiring continues its merry
way in an enclosed raceway that it's OK to switch to standard, and cheaper,
THHN-2/THWN-2 conductors.

 

Yes?

 

Thanks,

marco
