Terminal block, 6 gauge wire

[Kcmusa]

Bringing solar panel wire to box with 10 gauge wire, about 5 feet. Then I have about 30 feet to the fuse box, solar controller. I want to switch to 6 gauge wire but can’t find a terminal block that handles that size. Any recommendations.
this is for a 5th wheel RV setup.

Assuming you need two posts (for positive and negative) I have found these to be cost effective (I’m cheap).

Not their intended purpose but it gives you two posts at a hard to beat price.

Just be careful hooking things up.

What's the size of your system and the number of panels you have? If you have an MPPT controller, you can wire panels in series to get higher voltage for longer runs. I have arrays wired for 120VDC, which I can run ~135' to my combiner box, which can handle 4 gauge wire.

For example, wiring two 250W panels in series to get 60VDC at 8amps, you'd get less than 0.6V drop with a distance of 30'.
