. Use copper supply wires. Use the electric wires over the rating voltage 300 .
Total operating current of the indoor unit
F0 = 15 A or less *2
F0 = 20 A or less *2
F0 = 30 A or less *2
Apply to IEC61000-3-3 about max. permissive system impedance.
*1 The Ground-fault interrupter should support inverter circuit.
The Ground-fault interrupter should combine using of local switch or wiring breaker.
*2 Please take the larger of F1 or F2 as the value for F0.
F1 = Total operating maximum current of the indoor units × 1.2
F2 = {V1 × (Quantity of Type1)/C} + {V1 × (Quantity of Type2)/C} + {V1 × (Quantity of Type3)/C} + {V1 × (Quantity of Type4)} + {V1 × (Quantity of Others)/C}
