50 amps through #8 cord is pushing it pretty hard.
50 amps on 8 cord 240 is only rated for 40 amps continuous, before heat become a big problem. If you'll see over 40 amps continuous, or the run is long, go with 6 gauge instead. I have a 15 ft run from sub panel to a 32 amp continuous load wired by a licensed electrician to a NEMA 15-40 outlet in 8 ga copper wire. I see a voltage drop from 245 to 239-240V in that 15 ft run when the EVSE for recharging the 24 kw battery on the electrical car kicks in.
Not happy with that loss and attendant heat, I will probably rewire it with 6 gauge through the conduit.
