Check with your electrical supply store. There's an adapter block ( I don't
know what it's called) available that takes up 2 spaces on the ground bar
and has a larger lug on it.

But, as another poster mentioned, #4 should fit. Try running the screw
almost all the way out. #4 wire fit my CH panel, but it took some effort to
get it in there.

I have a siemens panel, and I got some #4 stranded copper wire to
connect to the ground rods, and water pipes. But when I go to connect
it to the ground/neutral bar, it is too big(just a little too big) to
fit in the slots. Is there another peice that is supposed to be for
this, or do I need to go back and get solid #4 for the ground wire (and
will solid #4 fit).

Thanks!
