Question 1
A discussion centres on Implement Ventilation, Containment, and Clearances for ESS. Which
heading best describes its subject?

A. Install Electrical Equipment (8%)
B. Install Raceways (7%)
C. Install System Monitoring, Control, and Communication Hardware (3%)
D. Install Battery Equipment (7%)

Correct Answer: D
Full Explanation: Install Battery Equipment (7%) is the most direct match because its subject
matter includes Implement Ventilation, Containment, and Clearances for ESS. By contrast, Install
System Monitoring, Control, and Communication Hardware (3%) concerns Mount Data Loggers,
Sensors, and Communication Gateways. The relevant distinction is the specific focus of the
discussion, rather than a broad similarity between topics.



Question 2
Which ordered set of topics best matches the following discussion points?
1. Ensure Clearances and Accessibility Requirements per Code
2. Pull, Terminate, and Secure DC Wiring

A. 1: Install DC PV System Conductors (8%); 2: Install Electrical Equipment (8%)
B. 1: Install DC PV System Conductors (8%); 2: Install DC PV System Conductors (8%)
C. 1: Install Electrical Equipment (8%); 2: Install Electrical Equipment (8%)
D. 1: Install Electrical Equipment (8%); 2: Install DC PV System Conductors (8%)

Correct Answer: D
Full Explanation: The correct associations are 1 with Install Electrical Equipment (8%) (Ensure
Clearances and Accessibility Requirements per Code); 2 with Install DC PV System Conductors
(8%) (Pull, Terminate, and Secure DC Wiring). Exchanging these topics changes the subject of one
or more concerns rather than preserving their distinct meanings.

Question 3
A discussion centres on Assemble Racking, Torque Tubes, and Structural Modules. Which
heading best describes its subject?

A. Install Ground-Mounted Structure (5%)
B. Install Grounding and Bonding (10%)
C. Install PV Modules (8%)
D. Install Battery Equipment (7%)

Correct Answer: A
Full Explanation: Install Ground-Mounted Structure (5%) is the most direct match because its
subject matter includes Assemble Racking, Torque Tubes, and Structural Modules. By contrast,
Install Grounding and Bonding (10%) concerns Install Equipment Grounding Conductors (EGC) and
Grounding Electrode Systems (GES). The relevant distinction is the specific focus of the
discussion, rather than a broad similarity between topics.



Question 4
A task combines Install Grounding and Bonding (10%) with Install System Monitoring, Control,
and Communication Hardware (3%), but the current discussion only considers Execute WEEB,
Lug, and Structural Bonding Connections. Which concern would supply the missing focus?

A. Pull, Terminate, and Secure DC Wiring
B. Terminate Data Lines (Ethernet, RS-485, Cellular Antennas)
C. Implement Ventilation, Containment, and Clearances for ESS
D. Manage Voltage Drops, Ampacity, and Temperature Corrections

Correct Answer: B
Full Explanation: The existing discussion concerns Install Grounding and Bonding (10%),
specifically Execute WEEB, Lug, and Structural Bonding Connections. To add the second focus,
Install System Monitoring, Control, and Communication Hardware (3%), the relevant material is
Terminate Data Lines (Ethernet, RS-485, Cellular Antennas). Adding more material from the first
topic would not address the missing second concern.

Question 5
Which answer gives the correct topic for each numbered focus, without exchanging their roles?
1. Connect Subpanels, Switchboards, and Inverter AC Outputs
2. Route and Terminate AC Interconnection Conductors
3. Manage Module-Level Electronics (Optimizers and Microinverters)
4. Execute Proper Wire Management and Connector Mating

A. 1: Install DC PV System Conductors (8%); 2: Install PV Modules (8%); 3: Install AC PV System
Conductors (8%); 4: Install AC PV System Conductors (8%)
B. 1: Install AC PV System Conductors (8%); 2: Install AC PV System Conductors (8%); 3: Install PV
Modules (8%); 4: Install DC PV System Conductors (8%)
C. 1: Install AC PV System Conductors (8%); 2: Install DC PV System Conductors (8%); 3: Install
PV Modules (8%); 4: Install AC PV System Conductors (8%)
D. 1: Install AC PV System Conductors (8%); 2: Install AC PV System Conductors (8%); 3: Install
DC PV System Conductors (8%); 4: Install PV Modules (8%)

Correct Answer: B
Full Explanation: The correct associations are 1 with Install AC PV System Conductors (8%)
(Connect Subpanels, Switchboards, and Inverter AC Outputs); 2 with Install AC PV System
Conductors (8%) (Route and Terminate AC Interconnection Conductors); 3 with Install PV Modules
(8%) (Manage Module-Level Electronics (Optimizers and Microinverters)); 4 with Install DC PV
System Conductors (8%) (Execute Proper Wire Management and Connector Mating). Exchanging
these topics changes the subject of one or more concerns rather than preserving their distinct
meanings.



Question 6
Several different issues need to be distinguished. Which answer identifies their topics in the
order shown?
1. Manage Module-Level Electronics (Optimizers and Microinverters)
2. Position and Secure Energy Storage Systems (ESS) and Enclosures

A. 1: Install PV Modules (8%); 2: Install Battery Equipment (7%)
B. 1: Install Battery Equipment (7%); 2: Install PV Modules (8%)
C. 1: Install PV Modules (8%); 2: Install PV Modules (8%)
D. 1: Install Battery Equipment (7%); 2: Install Battery Equipment (7%)

Correct Answer: A
Full Explanation: The correct associations are 1 with Install PV Modules (8%) (Manage
Module-Level Electronics (Optimizers and Microinverters)); 2 with Install Battery Equipment (7%)
(Position and Secure Energy Storage Systems (ESS) and Enclosures). Exchanging these topics
changes the subject of one or more concerns rather than preserving their distinct meanings.
