• D. To regulate the pump's speed

Answer 1

Answer:

B. To prevent water ingress into the motor

The cable gland in a submersible pump serves a crucial role in ensuring the longevity and proper functioning of the pump. Its primary function is to prevent water ingress into the motor, which is essential for maintaining the integrity and performance of the pump. Without this protection, water could enter the motor housing, leading to potential electrical failures and damage. Therefore, the cable gland acts as a seal, safeguarding the motor from external water exposure.
