Background: John, a Homeowner from Forrest hills, NY
Thanks for your electrical question John.
When installing wire in underground PVC conduit use THWN, not THHN.
Please see the link below to calculate the wire size for running the circuit 300 feet so you can factor in voltage drop.
I have provided the following links that lead to fully detailed information on this website that will assist you with your electrical question:
