NOTE: The default size of conduit connector is M20x1.5.
Note1.The above values represent constant current.
2.The so-called inductive load refers to the load with power factor of 0.4 or more (AC) and the time constant below 7ms (DC).
3.The so-called lamp load refers to the load with 10 times of surge current. 4.The so-called motor load is the load with 6 times of surge current.
