Southwire says low probability of jam. I just don’t believe it. This is 480 volts. 250 amps. Probably don’t need the neutral. For my conduit extruder line.
Last time I priced aluminum, since it had to be larger, the cost was similar. That was at Home Depot though.

I try to contract that out if possible. I do find that the jam probably on the southwire wire fill calculator is helpful as it gives a likihood of wires getting stuck. Just curious what are you powering that needs 4/0 copper? That's a lot of power. If this is this 120/208 is moving to 277/480 a possibility? (And if this is 480V, I'm really curious about what you're hooking up) And do you really need a neutral? One note is that aluminum is a fair bit easier to pull and has similar ampacity at the larger sizes. Plus it's a lot cheaper.

I will have two sweeps and at least 2 LBs. As much as I hate to, I really think I should use larger conduit. I really hate it when I have trouble pulling larger cables in too small of a conduit.
