The capacity of ELB, MCCB X[A] = 1.25 X 1.1 X ∑Ai
Decide the capacity of ELB and MCCB by below formula.
Decide the power cable specication and maximum length within 10% power drop among indoor units.

∑Ai : Sum of Rating currents of each indoor unit.
❈
Refer to each installation manual about the rating current of indoor unit.

Calculation
- Installing with 1 sort wire
❈
If the terminal input pressure of the indoor unit goes down by more than 10%, install the thicker wire.
- Installing with 2 dierent sort wire
