：
Ambient temperature
：
30
℃
.
AC loss less than 3%
，
DC loss less than 1%
，
The length of the AC power cables are no longer
than 50 m and the length of the DC power cables are no longer than 30 m.
Currents listed in the table are based on the 208V system (Line-to-line voltage).
The size of neutral lines should be 1.5~1.7 times the value listed above when the predominant
load is non-linear.
