Ideas for connecting #6 wire to 10# outdoor pv wire

[andykee]

I was wondering if anyone had any ideas other than a j-box, compression/cable gland and insulated lug for a connection between a #6 and #10 wire on a very long pv run. MC4's run between 8-14 gauge so I think that's out.

Wire nut? (outdoor type?) I don't know how to avoid the j-box and cable gland. Pretty much all NEC wiring methods require a box for splices. I was trained to use Buchanan splice caps but they are not actually rated for outdoors.

Are both wires PV wire? (i.e. would you not need a box to transition anyway?)

I do feel your frustration.

If the cable is rated for cable tray and he puts it in cable tray...

approved methods shall be permitted to be located within a
cable tray, provided they are accessible. Splices shall be
permitted to project above the side rails where not subject
to physical damage.
