There is no twist-on connector listed for 8 #12 so your best best is to use a small ground bar kit. It's definitely better than trying to splice that many wires under a twist-on connector anyway, even if you could do it.

I agree w/ Peter d about a bar.

But if you insist on using wire nuts, you could use a couple of the Dryconn blues with a jumper between them (IIRC those max out at 4 or 5 #12s per unit).

That or an 8 port WAGO:

afaik, the largest wire nut is rated for 5 #12s. Some are rated for 5 #10s, tho there is no translation for if or how many #12s it could hold.
 
I would go with the 2-5 wire splices jumpered together. Just use the correct wire nuts.

There are all kinds of options.

Wire nuts and terminal strips are probably the simplest.

Wire nuts are probably the fastest solution.

These are $2-3 each. I think you can get two wires on each side so you would only need two of them and a small piece of DIN rail to mount them on.

Actually, I never gave it a thought. Are wire nuts suitable for outdoor connections?

I believe only those listed for it, such as DryConn.

I don't think the WAGO are, just wondering if anyone can enlighten with specific info.

Looking for something better than a Buchanan splice filled with Noalox, which isn't listed but which I personally trust a whole lot more than a wirenut with slippery goop inside.

Even twist on connectors probably have similar rating. I have been looking a little but found nothing yet on WAGO site, but wonder if one doesn't need to look in the UL white book.

I would guess either is rated for use in wet/damp location enclosures, but not in submersible applications.
