Yes it will supply loads with three wires on 240, but it may also kill the user of a metal cased tool if the neutral breaks or corrodes in two as aluminum will if the insulation is breached. Also an aluminum neutral connection overstressed by a shorted cord can sometimes go open. And I've seen both happenings kill the tool users, more than once. I wasn't there. I had to investigate why and explain it to the survivors and their insurance companies. Sometimes to a jury. So I'm more than a little picky about that fourth wire.
After 4/0 wire common wire sizes are 250 MCM, 300 MCM, 350 MCM, up to 4000 MCM usually in 50 MCM steps... 250,000 circular mils cross section. M for 1000, CM for circular mils cross section. A circular mil is a wire .001" diameter having an area of pi/4 mil squared. So a solid conductor 250,000 CM would be 0.500" diameter. A stranded conductor is larger because of the air spaces between the strands. Circular mils are a little more logical than wire gauges (different for iron than copper, and different for different countries), but are a short hand ignoring the pi/4 factor by simply squaring the diameter.
After doing a 4/0 wiring job, I set my limits at 0, hire someone else for the larger sizes, they take tools I don't have and muscles too.
