The pump has a built-in over current fuse and protection, temperature protection and basic

overvoltage protection. It does not need additional thermal protection switch. Connection leads

should be capable of carrying rated power and properly fused. Ground lead connection is

essential for safety. It should be connected first. Grounding is only meant for pump safety. Pipes

should be grounded separately.
