9-2-2. Cross section area of Wire for Main Power and ON/OFF capacities
1. Bear in mind ambient conditions (ambient temperature, direct sunlight, rain water, etc.) when proceeding with the wiring and connections.
2. The wire size is the minimum value for metal conduit wiring. The power cord size should be 1 rank thicker consideration of voltage drops.
Make sure the power-supply voltage does not drop more than 10%.
3. Specific wiring requirements should adhere to the wiring regulations of the region.
4. Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed flexible cord (design 60245 IEC57). For
example, use wiring such as YZW.
5. Install an earth line longer than power cables.

C: Multiple of tripping current at tripping time 0.01 s
Please pick up “C” from the tripping characteristic of the breaker.
<Example of “F2” calculation>
Condition PLFY-P·VBM-E × 4 + PEFY-P·VMA-E × 1, C = 8 (refer to right sample chart)
F2 = 19.8 × 4/8 + 38 × 1/8
= 14.65
→ 16 A breaker (Tripping current = 8 × 16 A at 0.01 s)
* 5
Current sensitivity is calculated using the following formula.
G1 = V2 × (Quantity of Type1) + V2 × (Quantity of Type2) + V2 × (Quantity of Type3) + ··· + V2 × (Quantity of Type15) +
V3 × (Wire length[km])
<Example of "G1" calculation>
When connecting 3 units of the SEZ-KD respectively to a branch box with a wire that is 20 m long and 1.5 mm² in diameter, then con -
necting the branch box and PEFY-VMA to a single breaker with a wire that is 100 m long in total and 2.5 mm² in diameter.
G1 = 2.4 × 3 + 3 + 1.6 + 48 × 0.02 × 3 + 56 × 0.1
= 20.28
