Hello, all. I was in Cedar Rapids, IA recently (I don't reside there) traveling along Rt. 100 (Collins Rd) in northeast of downtown. I noticed utility poles with a single cross arm accommodating 4 medium voltage (MV) line wires. This clearly wasn't the usual 3-phase MV distribution with 3 wires on the cross arm with the neutral attached to the pole below the cross arm. I later examined Google satellite images along this part of Collins Rd and it appears one of the 4 wires may be the neutral (not the same insulator as the other 3 wires but on some poles they were the same) but no indication if it's earthed at regular intervals. If any of you folks have further info it would be appreciated and instructive. Just never saw this arrangement before. Sincerely,
