I believe you're looking for something called a "cable gland".  You
want it liquid-tight or watertight or waterproof or whatever the
manufacturer calls it.  Try searching for "cable gland liquid".

I think this one will fit 2/0 cable:

If you've got a Fastenal nearby, check it out.  If they don't have it
in stock they'll order it for local pickup, no shipping costs.  I have
a strange and probably unhealthy fascination with that store.

Digikey has a bunch of cable glands.  No idea how to sort out which one
you need, sorry.  They have live online help, though, and it's actually
helpful.  Mouser seems to have cable glands and live online help too.

Perhaps an actual electrical supply place will have some cable glands
in stock.  Check your yellow pages.  Bring along a small chunk of your
2/0 so you can show it to them.

Online electrical supply places like Graybar.com will have cable
glands, too.

I just had a thought.  Hang on.... yes, my PFC-20 has a couple of cable
glands on it.  Nice aluminum ones, too.  Brand name of APPLETON.  Web
site <http://www.appletonelec.com>... they call it a "liquidtight
strain relief".  Part number CG-62100 should fit 2/0.
