,1. When diagnosing or planning work, which statement is most accurate about Water
well pump systems include pumps, motors, drop cables, controls, piping, and
associated equipment.. Which answer best applies to the underlying ES-10J water well
pump installer concept in this situation?
A. Drop cables must be suitable for the environment and protected against damage..
B. Pump selection should match well conditions, required flow, head, and system pressure..
C. Water well pump systems include pumps, motors, drop cables, controls, piping, and
associated equipment..
D. Motors require suitable voltage, protection, cooling, and connections..
Correct answer: C
Rationale: The correct choice directly states the governing principle: Water well pump systems
include pumps, motors, drop cables, controls, piping, and associated equipment.. The
alternatives address related topics but do not directly answer the issue being tested.
2. Which statement most accurately explains the principle involved when Pump
selection should match well conditions, required flow, head, and system pressure..
Which answer best applies to the underlying ES-10J water well pump installer concept
in this situation?
A. Pump selection should match well conditions, required flow, head, and system pressure..
B. Motors require suitable voltage, protection, cooling, and connections..
C. Drop cables must be suitable for the environment and protected against damage..
,D. Pump controls may include pressure switches, control boxes, disconnects, or other
equipment..
Correct answer: A
Rationale: The correct choice directly states the governing principle: Pump selection should
match well conditions, required flow, head, and system pressure.. The alternatives address
related topics but do not directly answer the issue being tested.
3. During a service situation, which option best describes why Motors require suitable
voltage, protection, cooling, and connections.. Which answer best applies to the
underlying ES-10J water well pump installer concept in this situation?
A. Drop cables must be suitable for the environment and protected against damage..
B. Pressure systems require appropriate tanks, controls, relief provisions, and piping..
C. Motors require suitable voltage, protection, cooling, and connections..
D. Pump controls may include pressure switches, control boxes, disconnects, or other
equipment..
Correct answer: C
Rationale: The correct choice directly states the governing principle: Motors require suitable
voltage, protection, cooling, and connections.. The alternatives address related topics but do
not directly answer the issue being tested.
4. A technician is evaluating a condition; which response is most appropriate because
Drop cables must be suitable for the environment and protected against damage..
, Which answer best applies to the underlying ES-10J water well pump installer concept
in this situation?
A. Pressure systems require appropriate tanks, controls, relief provisions, and piping..
B. Grounding and bonding provide intended electrical fault paths and shock protection..
C. Pump controls may include pressure switches, control boxes, disconnects, or other
equipment..
D. Drop cables must be suitable for the environment and protected against damage..
Correct answer: D
Rationale: The correct choice directly states the governing principle: Drop cables must be
suitable for the environment and protected against damage.. The alternatives address related
topics but do not directly answer the issue being tested.
5. Which choice correctly identifies the main reason that Pump controls may include
pressure switches, control boxes, disconnects, or other equipment.. Which answer best
applies to the underlying ES-10J water well pump installer concept in this situation?
A. Pump controls may include pressure switches, control boxes, disconnects, or other
equipment..
B. Testing should verify electrical performance, pressure, flow, and system operation as
applicable..
C. Grounding and bonding provide intended electrical fault paths and shock protection..
D. Pressure systems require appropriate tanks, controls, relief provisions, and piping..
