Probably overkill but I can't hurt anything but your wallet. Be sure to use conduit large enough to accommodate all three conductors (L1. L2, Ground). If the path has many 90's and 45's that will make pulling harder too. You probably want 1.5 or 2.0 inch conduit.

What size breaker did you use in main panel that feeds your sub panel? That is the key to me. I id my own but used the GE Subpanel just like your Connecticut Electric. I love Connecticut Electric when I can afford it
But I digress, I used a GE 60 amp Breaker that feeds my subpanel; so I can use all of the 30 & 20 amps with no issues. It is highly unlikely I ever trip the 60 amps breaker without 1st tripping the 50 or 20 amp on subpanel. Besides at Home Depot the 60 amp was the highest I could find
