yeah i can see one of few worst mess but this set up i did ran into few time but have to look out on one box on upper right corner it have 3 phase power there for central air conding it was common during late 60 to early 70's but now days it is history now because hard to deal with 4 wire delta service only few place in major citys still have that for resdentail service now but i heard some rumours but i dont have any fact some area might go with true 3 phase wye serice but keep in mind i just heard rumors that all

merci marc
