SUMMARY
The wire size requirements for a 380V three-phase Fan Coil Unit and Air Handler Unit are determined by their respective power ratings and circuit lengths. The Fan Coil Unit operates at 3.7kW with a circuit length of 70 meters, while the Air Handler Unit operates at 5.5kW with a circuit length of 24 meters. Full load amperage and recommended breaker sizes for these units can be found in their submittals, and wire size specifications are governed by electrical code, specifically referenced in the provided link to Armstrong Supply's wire chart.
