Any electricians available? Wire size question...

View attachment 1715042075 if you want only 220 service you can get by with only 3 wires (you can omit the neutral)..

Why anyone would do this over the price of one more wire does not make sense. It aways seems like a lot when the trench is dug, 2-10 years from now you forgot all aboout it
