What size PVC will the UMC wand fit through?

Hi guys,
Changed my mind on the wall mounted box for my semi-permanent UMC setup. Going to put the Nema 14-50 outlet on the inside of the garage, then run the wand thru a hole with PVC. I don't pickup the car till later this week, and my guy is coming tomorrow to run the electrical. What size hole/PVC do I need? 2 inch?
Thanks

I need the UMC wand to fit through the hole. I don't think wire size matters as it will be smaller than the wand head.
