What is the requirement regarding electrical connections for pumps?

1. Must be placed outside the tank

2. Should be waterproof

3. Can be placed inside the tank

4. Must be placed in the tank

The correct answer is: Must be placed outside the tank

The requirement regarding electrical connections for pumps emphasizes that they must be placed outside the tank. This is crucial for safety and operational reliability. Having electrical connections located outside of the tank helps prevent any potential electrical hazards that may arise from water exposure or leakage, which could lead to short circuits or electrical shock. Placing connections outside also makes maintenance and repairs easier because it allows for safer access to the electrical components without the risk of water contact. In many applications, this practice is in line with safety standards and electrical codes, which are designed to minimize risks associated with moisture and electrical systems. The other options do not align with safety and installation best practices. For instance, waterproofing connections is important, but it doesn't address the primary safety concern of placement. Similarly, placing connections inside the tank or burying them under water would pose significant risks and is generally not permitted by electrical codes. Thus, the emphasis on outside placement supports both safety and compliance in residential contracting practices.
