Max wire size?

Hello Eric, Thank you for your question. You may use wire size 14-10 for torque 32-35, wire size 8 for torque 36-40, wire size 6-4 for torque 41-45, and wire size 3-2/0 for torque 45-50. Regards, Eaton

I used number 6 - 3 wire plus ground and it was a very tight fit. I came in from the bottom thru a conduit.
