VD & 20A Ckts

[mstrlucky74]

Have a 208v motor feed from a 1P-20a circuit. The motor is about500’ away. I’m coming up with #8’s in a single conduit…if I combine a 3 circuithomerun I’m coming up with #6’s. This is to keep the VD under 3%. Does thismake sense and if so I can’t use a 20a breaker. Correct? Thanks.

What's the motor current?

Without knowing more details, an alternative might be to run a feeder to a sub-panel near the loads, if I'm understanding your "3 circuit home run" correctly.

I believe 7 amps

I got #6 @ 7A also. OCPD would be based on 430.52 and FLA from tables in 430. It very well could be a 20A.
