John, Actually I did see an 84. It was in new construction. They ended up putting two circuits on each breaker. The lights in the owners office and the vending machines shared a breaker and kept tripping. The panel was single phase 120 / 240 volt supplied from a three phase 120 / 240 volt service. The prints showed a transformer and the contractor actually charged the customer for it. Low bidders and cheap customers make life interesting. Alan--
