I missed the 1/2" requirement in my last reply - this is the corrected

Can you get the 6-3 cable through the required cable connector, is
the big question. If you can fit the 6-3 into the connector that
threads into the 1/2" knockout, you are gold.

WRONG. The big question is whether the required cable connector is listed for use with 6-3
cable. If the connector is not listed for use with 6-3 cable, it's a Code violation to use it for
that, whether the cable fits or not.
Well, you show me a 1/2 inch romex connector that will take a 6/3 cable that
isn't listed for use with 6/3 and you may have a point. The POINT is,
there is no romex connector that WILL accept a 6/3 AND fit a 1/2" hole - listed or not..
