Re: Conduit Size for 6-3 NM I would strongly advise against running 6/3 romex or UF through PVC conduit for a lot of reasons.
If you insist on doing it, you are going to want to upsize the conduit drastically to cope with the wires "unwillingness". I'd say 2". If it's just a short stub with no bends, then 1".
The proper way would be to install individual conductors correctly rated for the environment in which they will be installed (typically THHN/THWN for outdoor and buried applications.
If someone refers to herself / himself as a "guru", they probably aren't.
