How to connect the explosion-proof motor
Check the clearance and creepage distance after the junction box is installed: 380/660V minimum clearance 10mm, creepage distance minimum 18mm. The minimum electrical clearance of 1140V is 18mm, and the creepage distance is a minimum of 30mm.
The incoming line of the junction box is sealed by pressing the rubber ring. The weakness of this structure is the aging of the rubber ring, the elastic failure, and the cable and the rubber ring are inconsistent.
For the junction box of the double outlet, the unused outlet should be blocked with a metal seal of not less than 2mm. The outer diameter of the metal seal should be similar to the inner diameter of the outlet of the inlet and outlet device to ensure the pressure plate or compression nut. Evenly press the seal to achieve a reliable seal.
