How hard is this cable pull?

[hillbilly1]

Shouldn’t be hard, I’ve done longer runs that size by myself using a small handheld Greenlee tugger. Will the wire be on reels? Or laid out on the floor? One guy on the feed end, the rest pulling.

And thats only for 240 three phase not 208 right?

You need to have minimum EGC size for the feeder but the nuetral issue on 208 isn't reducing size it's whether it's a CCC or not in pipe.

You could shrink the ground and neutral, might save some $$
If its a 200A feeder you only need a #6 EGC

You could, but green wires give a warm feeling to those that require them and larger green wires give an extra dose of that good feeling.

And I have reduced the neutral to a #1/0 but some don't approve of that an prefer a full size as many 240V deltas are eventually converted to a 208 or I am not sure why really,

There is never a practical reason not to reduce a neutral and is always allowed by code. There were some rare cases on 208V three phase systems that harmonics from non linear loads could overload a neutral but that hasn't been an issue for decades. There are often job specs or local amendments that don't allow it.

I'd add that a open wye (two phases and a neutral from a 4-wire 3-phase wye) the neutral has to be full size 220.61(C)(1) and that neutral with 120 deg phase angles will carry more current than a truely 'single phase' 3-wire 120/240 circuit 180 deg phase angles. Nothing special about 208 though its the phase angles of open wye.
