It is required to install 10 split of 18000 BTU c / u of 220V with a 7.7 A consumption with a power of 1600 Watts per split, the service in the area is single-phase two-wire (FN) 127 V. The question is the following. Will the 16000W total load of the 10 split support the 3-wire single-phase service (some know it as two-phase) or will a three-phase service be required? Will it be necessary to contemplate a transformer? This is contemplating the pure load of climates missing the 2000w load that was installed, Thank you for your support
