C: Multiple of tripping current at tripping time 0.01s
Please pick up ˝C˝ from the tripping characteristic of the breaker.
<Example of ˝F2˝ calculation>
Condition PEFY-VMS × 4 + PEFY-VMA × 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 Type16)
+ V3 × (Wire length[km])
G1 Current sensitivity

Notes:
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
