Combining wire in junction box

[Bluedog225]

For my temp setup, I’m going to keep it a 2 string. I’ll need to combine three 10 awg in a junction box.

No fuses or breakers.

Is it ok to simply wire nut them together? I wouldn’t hesitate with alternating current but wanted to check if that was ok with DC?

10 awg thhn, “solar panel” wire, 20 amps and around 130 volts.

Thanks

Yes
It doesn't matter if it's AC or DC.
Unless you are trying to disconnect under load.

Great. Thanks Tim.

I use these sealed butt connectors and skip the box.

That’s handy. I didn’t know such a thing existed. Thanks!

I wonder if there are any issues with lever connectors. I’ve not used many but they seem handy.

Below is a test of the clamping force of lever nuts on 16AWG wire. The lever nuts performed well.

Below is a test of wire nuts vs. lever nuts, both hung from a vibratory tool. Surprisingly, the wire nuts performed as well as the lever nuts.

Are the lever nuts compatible with the coarsely stranded wire?

Good question. It looks like yes.
