[RE-wrenches] double-insulated PV wire

[Marco Mangelsdorf]

Note that this also assumes that the conductor whips from the modules ARE
ALSO double insulated if they're to be used with TL inverters.  Some mods
have 'em, some do not.

Good point.  If one can position transition boxes close enough to the
modules, you can use only the leads from the modules, avoiding the need to
buy any PV wire.  It is surprisingly easy to do.  See:

double-insulated wire has to be used from the module series string to the
first enclosure and enclosed raceway where the transition to standard
THHN/THWN wire can be made.
