Yes the miners use 208-240VAC.
Why do folks keep asking about 120v when they are clearly spec'ed for 208-240? Hell, it's even stamped on the PSU, can't they read?
As for where you got the idea that 2x 120v outlets might = 240v, that's one I've never heard before.... huh
If you are in North America you need a L6-15 or L6-20 outlet at the wall. A L6-20 duplex outlet (2 sockets) fused for 20A and L6-15 ends on the cords would be perfect as it protects the miner by having both power inlets protected by 1 fuse/breaker - no chance of blowing one feed while the other tries to stay alive... The C13 end is correct but frankly 18ga wire is too small, I prefer at least 16ga with 14ga cords being ideal.
