Question 1
Match each numbered concern to its subject area. Which answer preserves all of the
associations?
1. Fire code requirements (setbacks, rapid shutdown, pathways, smoke ventilation)
2. Architectural, structural, and electrical drawing verification
A. 1: 1 Project Plan and Specification Review; 2: 1 Project Plan and Specification Review
B. 1: 2 Permits, Codes, and Regulatory Compliance; 2: 2 Permits, Codes, and Regulatory
Compliance
C. 1: 2 Permits, Codes, and Regulatory Compliance; 2: 1 Project Plan and Specification Review
D. 1: 1 Project Plan and Specification Review; 2: 2 Permits, Codes, and Regulatory Compliance
Correct Answer: C
Full Explanation: The correct associations are 1 with 2 Permits, Codes, and Regulatory
Compliance (Fire code requirements (setbacks, rapid shutdown, pathways, smoke ventilation)); 2
with 1 Project Plan and Specification Review (Architectural, structural, and electrical drawing
verification). Exchanging these topics changes the subject of one or more concerns rather than
preserving their distinct meanings.
Question 2
Keep these concerns distinct. Which sequence of topics correctly matches the numbered
descriptions?
1. voltage drop, conduit fill, conductor sizing, and short-circuit current ratings
2. 2 Racking, Mounting Systems, and Modules
A. 1: Calculation verification; 2: Structural and Mechanical Inspection
B. 1: Calculation verification; 2: Calculation verification
C. 1: Structural and Mechanical Inspection; 2: Calculation verification
D. 1: Structural and Mechanical Inspection; 2: Structural and Mechanical Inspection
Correct Answer: A
Full Explanation: The correct associations are 1 with Calculation verification (voltage drop,
conduit fill, conductor sizing, and short-circuit current ratings); 2 with Structural and Mechanical
Inspection (2 Racking, Mounting Systems, and Modules). Exchanging these topics changes the
subject of one or more concerns rather than preserving their distinct meanings.

Question 3
Both 2 ESS Electrical Protection and Disconnects and 1 Battery and Storage Hardware
Integration need attention. Work has so far concentrated on Overcurrent protection and BMS
(Battery Management System) integration. Which topic-specific addition is still needed?
A. Overcurrent protection and BMS (Battery Management System) integration
B. DC and AC disconnects specific to energy storage systems
C. Separation distances from ignition sources, living spaces, and egress paths
D. Module, racking, and enclosure continuous bonding paths
Correct Answer: C
Full Explanation: The existing discussion concerns 2 ESS Electrical Protection and Disconnects,
specifically Overcurrent protection and BMS (Battery Management System) integration. To add
the second focus, 1 Battery and Storage Hardware Integration, the relevant material is Separation
distances from ignition sources, living spaces, and egress paths. Adding more material from the
first topic would not address the missing second concern.
Question 4
A task combines 1 Inverters and Power Conversion Equipment with Grounding and Bonding
Inspection, but the current discussion only considers Grid-tied, off-grid, and hybrid inverter
settings and operational verification. Which concern would supply the missing focus?
A. 1 Equipment Grounding and Bonding (EGC)
B. Inverter placement, mounting security, and environmental clearances
C. Fall protection systems and personal protective equipment (PPE)
D. Grid-tied, off-grid, and hybrid inverter settings and operational verification
Correct Answer: A
Full Explanation: The existing discussion concerns 1 Inverters and Power Conversion
Equipment, specifically Grid-tied, off-grid, and hybrid inverter settings and operational
verification. To add the second focus, Grounding and Bonding Inspection, the relevant material is
1 Equipment Grounding and Bonding (EGC). Adding more material from the first topic would not
address the missing second concern.

Question 5
A task combines 1 Worker and Public Safety Verification with 2 DC Combiner Boxes,
Disconnects, and Overcurrent Protection, but the current discussion only considers Fall
protection systems and personal protective equipment (PPE). Which concern would supply the
missing focus?
A. DC wire management, support intervals, and abrasion protection
B. DC and AC disconnects specific to energy storage systems
C. Enclosure ratings (NEMA/IP types) and environmental protection
D. AC overcurrent protection device (OCPD) sizing and selection
Correct Answer: C
Full Explanation: The existing discussion concerns 1 Worker and Public Safety Verification,
specifically Fall protection systems and personal protective equipment (PPE). To add the second
focus, 2 DC Combiner Boxes, Disconnects, and Overcurrent Protection, the relevant material is
Enclosure ratings (NEMA/IP types) and environmental protection. Adding more material from the
first topic would not address the missing second concern.
Question 6
Which paired description correctly distinguishes 2 AC Disconnects, Combiners, and
Interconnection Panels from 2 Racking, Mounting Systems, and Modules?
A. 1: Utility interconnection metering equipment, production meters, and disconnect
accessibility; 2: Utility interconnection metering equipment, production meters, and
disconnect accessibility
B. 1: Module securement, clamping pressure, placement, and clamp orientation; 2: Module
securement, clamping pressure, placement, and clamp orientation
C. 1: Module securement, clamping pressure, placement, and clamp orientation; 2: Utility
interconnection metering equipment, production meters, and disconnect accessibility
D. 1: Utility interconnection metering equipment, production meters, and disconnect
accessibility; 2: Module securement, clamping pressure, placement, and clamp orientation
Correct Answer: D
Full Explanation: The first topic, 2 AC Disconnects, Combiners, and Interconnection Panels,
includes Utility interconnection metering equipment, production meters, and disconnect
accessibility. The second, 2 Racking, Mounting Systems, and Modules, includes Module
securement, clamping pressure, placement, and clamp orientation. Reversing the two or
repeating the same discussion point for both would lose the distinction required by the question.
