Do they make MC4 connectors for wires larger than 10 AWG?

What about for 8 gauge wire or 6 gauge wire? Any MC4's ?

Or what about just trimming off a few strands to get 8 gauge wire to fit in a 10 gauge MC4 sleeve?

Why you need more flow area than a #10? You making crazy long runs? Running low voltage? If absolutely necessary I'd splice a #10 to something bigger rather than trimming strands out of a larger bundle, but I'm curious why you need to do that? Sounds like it might be $$ being spent on wire that might be able to be designed around for lower expense.

Typically the MC4 connectors are used at the individual panels and possibly at the input to a DC combiner.
It would be a rare situation where the wire attached to an MC4 would either carry current from multiple strings or panels in parallel or run a long distance.
I would expect the larger wire size to be on the output side or a combiner or fused disconnect, where you could use either a different connector or no connector at all (hard wired to terminals.)
Building a combiner for three or more panels in parallel using MC4 wye connections does not make a lot of sense, since you will require per-string fuses anyway.
