Power cable length

The length of the standard power cable provided in the design of the pump.

Ideally, the length of this cable should not be less than the maximum immersion depth — this will ensure maximum ease of connection: the connection point of the cable to the mains will be above the water (in the best case, even outside the well), and you will not have to worry about insulation. At the same time, for several reasons, many pumps are equipped with rather short cords — about 1.5-2 m, and not long cables; in such cases, it is necessary to use special waterproof equipment.
