Choosing between 3 pin and 2 pin cords often depends on the specific appliance and its power requirements. Ni-San Cords recommends 2 pin cords for low-wattage devices that do not require grounding, as this can reduce costs and space. For office equipment, industrial machines, and major home appliances, 3 pin cords are essential to ensure both user safety and device longevity. https://medium.com/@contactnisancords/3-pin-power-cord-manufacturers-in-maharashtra-ni-san-cords-0e5178adcba1
