Q32. Thermal imaging infrared cameras can be used to help find which of the following system operational issues?

Intensity of solar insolation to determine power output

Battery state of charge in a multimode system

Blind spot fault in a source circuit

Loose PV input circuit terminations in a combiner box

Q33. An installer is hired to troubleshoot a 10-year-old roottop system with open-circuitvoltage of 300V. The ground-fault detection (GFD) device has tripped. The insulation on the exposed source circuit cables has deterlorated with multiple cracks and has no flexibility. Which concern is the MOST likely safely issue when servicing this array?

Insulation has become an electrical conductor since it has changed its composition.

Cracked insulation has allowed water intrusion that resulted in oxidation of the copper conductors.

Ungrounded conductors are conducing current event the ground-fault device has activated.

Short-circuit current is present at the PV source-circuit terminals of the disconnect device because of electrical leakage.

Q34. Which of the following is an NEC requirement regarding access for large-scale PV electric power production facilities?

Field-applied hazard markings must be installed, and access to the supply station is to be restricted by fencing or other adequate means.

All fencing and associated gates must have ac and dc current and voltage exposure labvels and must be electrically isolated from the solar facility.

Arc flash warning labels must be field-applied by the installer at all access points for qualified persons and at the point of the utility interconnection directory.

Access to remote isolating equipment for servicing is allowed for individual other than qualified persons when the equipment is enclosed within a secure structure.

Q35. An installer is using 1/2 in lag boits to secure roof-monitoring hardware to rafters through a roof deck. Which of the following should the installer predrill?

A pilot hole one-half the length of the bolt

A pilot hole one-fourth the length of the bolt

A 1/8 in, pilot hole through the roof into the rafter

A 5/16 in pilot hole through the roof into the rafter

Q36. A PV array with 58 in. X 38 in modules in portrait orientation is to be mounted at a 35 tiit angle on a shingle roof that has a 5:12 pitch. Assuming the support leg is attached to the top of the modules and is perpendicular to its face, what is the length of the support leg for the modules?

12.73 in.

18.25 in.

24.24 in.

40.50 in.

Q37. A customer has a 200A service with a 200A rated panel and 200A main breaker located on the street side of the house. There is a 100A breaker located at the opposite end of busbar feeding a 125A subpanel in the backyard. The customer would like to place the inverter the backyard and use the 125 subpanel. Which MAXIMUM inverter(s) output circuit current could be installed?

30A

32A

40A

42A

Q38. A residential PV system uses two 120.240Vac utility-interactive inverters with a sealed lead-acid battery energy backup for protected loads. The MOST important protected load consideration when operating in the backup mode is that:

The protected loads must have automatic restart function.

All protected loads are connected in multiwire branch circuits.

The peak current from the sealed lead- acid batteries must not exceed peak demand currents.

The stand-alone system configuration can adequately supply current to all protected load branch circuit.

Q39. Which electrical connection requires the use of a torque device to complete the connection per NEC requirements?

Crimp-on log to the battery cable

Screw terminals on an ac receptacle outlet

Underground direct-burial twist-on wire connector

Soldered splices in a conduit body

Q40. Which of the following tests measures axial uplift whenperforming load testing of driven-pile foundation members

Resistance to horizontal movement

Resistance to downward (Sinking force

Resistance to twisting

Resistance to withdraw (pull-out) force

Q41. An 8KWsc roof-mounted array is placed on a school building. The inverter is located within 1 ft, of the array boundary and has an integrated ac-and dc-disconnecting switch. The system is to be connected to a 400A load center, protected by a 400A main breaker. Which of the following MUST be included to meet NEC requirements?

A rapid shutdown initiationdevice operating contractor within 1 ft, of the array to de-energize the dc subarrays

A readily accessible dc disconnect with rapid shutdown initiation device permanently labeled

An ac-disconnect label with the location of the rooftop dc-disconnect switch.

A readily accessible ac-disconnecting switch, who location is identified on the system directory

Q42. According to the NEC, where on a residential PV system MUST the labeling describing the type of rapid shutdown be located?

On the rapid shutdown initiation device.

On or no more than 1 m (3. 3 ft) from the service disconnecting meant

At point on the residence designated by the AKJ and fire marshal

A close as practicable to the PV array requiring rapid shutdown

Q43. When running horizontal 1-1/4 in, electrical metallic tubing (EMT) with compression fittings, what is the MAXIMUM permissible distance between condult supports?

3 ft

10 ft

14 ft

20 ft

Q44. A commercial 600v carport-mounted PV system is installed with rigid running under the parking lot to an inverter pad located at the edge of the parking lot. At what depth below the parkinglot base MUST condult be buried?

12 in.

18 in.

24 in.

36 in.

Q45. Which of the following should a PV installer do during dc insulation resistance testing?

Wait until is raining and all wiring is damp to conduct the test.

Close ac and dc disconnects and have the system running for at least 5 minutes before testing.

Remove surge suppression equipment from the circuit being tested.

Connect the megohmmeters’s negative terminal to the dc circuit insulation

Q46. A7KW/ 14 KWh multimode systemhas been installed at a residence, ac-couple with the customer’s existing
6.7kwh ac PV system. The system providers uninterrupted power to a protect loads subpanel, which is connected to a refrigerator, Microwave, 1.0 ton are conditioner, three lightning circuit, and the 6.7kwac PV system. One month later, the homeowner moves additional circuits to the protected loads subpanel, substantially increasing the loads.
