@dassauerkraut@shortstacksran.ch I'd just have A and B to start and leave the 3rd phase empty of breakers. Then when I get the 3 phase service installed I'll have C phase. That's another issue tho, last time we priced getting 3 phase they wanted 20K to add cross bars and 2 wires for a half mile. Since now we will have two locations needing three phase maybe they will subsidize it a bit more, or I can split the cost with my friend because he wants 3 phase there too.
